.\nCDATA_CONTENT may contain any characters. The function of cdata is to forbid the validator to parse CDATA_CONTENT, so even it has some characters that can be parsed as tag (no matter valid or invalid), you should treat it as regular characters.\n\n \nExample 1:\n\nInput: code = \"This is the first line \"\nOutput: true\nExplanation: \nThe code is wrapped in a closed tag : and . \nThe TAG_NAME is valid, the TAG_CONTENT consists of some characters and cdata. \nAlthough CDATA_CONTENT has an unmatched start tag with invalid TAG_NAME, it should be considered as plain text, not parsed as a tag.\nSo TAG_CONTENT is valid, and then the code is valid. Thus return true.\n\nExample 2:\n\nInput: code = \">> ![cdata[]] ]>]]>>]\"\nOutput: true\nExplanation:\nWe first separate the code into : start_tag|tag_content|end_tag.\nstart_tag -> \"\"\nend_tag -> \"\"\ntag_content could also be separated into : text1|cdata|text2.\ntext1 -> \">> ![cdata[]] \"\ncdata -> \"]>\", where the CDATA_CONTENT is \"]>\"\ntext2 -> \"]]>>]\"\nThe reason why start_tag is NOT \">>\" is because of the rule 6.\nThe reason why cdata is NOT \"]>]]>\" is because of the rule 7.\n\nExample 3:\n\nInput: code = \" \"\nOutput: false\nExplanation: Unbalanced. If \"\" is closed, then \"\" must be unmatched, and vice versa.\n\n \nConstraints:\n\n1 <= code.length <= 500\ncode consists of English letters, digits, '<', '>', '/', '!', '[', ']', '.', and ' '.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(code = \"abc\") == True\n assert candidate(code = \"\") == True\n assert candidate(code = \"\") == True\n assert candidate(code = \"\") == False\n assert candidate(code = \"This is the first line \") == False\n assert candidate(code = \"\") == True\n assert candidate(code = \"\") == False\n assert candidate(code = \" 123 \") == False\n assert candidate(code = \"\") == False\n assert candidate(code = \" \") == False\n assert candidate(code = \"text \") == True\n assert candidate(code = \" ]]>\") == True\n assert candidate(code = \"abcdef\") == True\n assert candidate(code = \"sometext \") == True\n assert candidate(code = \"\") == False\n assert candidate(code = \"sometext \") == False\n assert candidate(code = \"\") == True\n assert candidate(code = \"sometext \") == False\n assert candidate(code = \"\") == False\n assert candidate(code = \"\") == True\n assert candidate(code = \"\") == True\n assert candidate(code = \"\") == False\n assert candidate(code = \"]]> \") == True\n assert candidate(code = \"contentcontent]]>content \") == False\n assert candidate(code = \" here]]> ]]> many

Your task is to perform a flood fill on the image starting from the pixel image[sr][sc].\nTo perform a flood fill:\n\nBegin with the starting pixel and change its color to color.\nPerform the same process for each pixel that is directly adjacent (pixels that share a side with the original pixel, either horizontally or vertically) and shares the same color as the starting pixel.\nKeep repeating this process by checking neighboring pixels of the updated pixels and modifying their color if it matches the original color of the starting pixel.\nThe process stops when there are no more adjacent pixels of the original color to update.\n\nReturn the modified image after performing the flood fill.\n \nExample 1:\n\nInput: image = [[1,1,1],[1,1,0],[1,0,1]], sr = 1, sc = 1, color = 2\nOutput: [[2,2,2],[2,2,0],[2,0,1]]\nExplanation:\n\nFrom the center of the image with position (sr, sc) = (1, 1) (i.e., the red pixel), all pixels connected by a path of the same color as the starting pixel (i.e., the blue pixels) are colored with the new color.\nNote the bottom corner is not colored 2, because it is not horizontally or vertically connected to the starting pixel.\n\nExample 2:\n\nInput: image = [[0,0,0],[0,0,0]], sr = 0, sc = 0, color = 0\nOutput: [[0,0,0],[0,0,0]]\nExplanation:\nThe starting pixel is already colored with 0, which is the same as the target color. Therefore, no changes are made to the image.\n\n \nConstraints:\n\nm == image.length\nn == image[i].length\n1 <= m, n <= 50\n0 <= image[i][j], color < 216\n0 <= sr < m\n0 <= sc < n\n\n",

The indices of the asteriod in the array represent their relative position in space.\nFor each asteroid, the absolute value represents its size, and the sign represents its direction (positive meaning right, negative meaning left). Each asteroid moves at the same speed.\nFind out the state of the asteroids after all collisions. If two asteroids meet, the smaller one will explode. If both are the same size, both will explode. Two asteroids moving in the same direction will never meet.\n \nExample 1:\n\nInput: asteroids = [5,10,-5]\nOutput: [5,10]\nExplanation: The 10 and -5 collide resulting in 10.

-{"question_id": 736, "task_id": "parse-lisp-expression", "difficulty": "Hard", "problem_description": "You are given a string expression representing a Lisp-like expression to return the integer value of.\nThe syntax for these expressions is given as follows.\n\nAn expression is either an integer, let expression, add expression, mult expression, or an assigned variable. Expressions always evaluate to a single integer.\n(An integer could be positive or negative.)\nA let expression takes the form \"(let v1 e1 v2 e2 ... vn en expr)\", where let is always the string \"let\", then there are one or more pairs of alternating variables and expressions, meaning that the first variable v1 is assigned the value of the expression e1, the second variable v2 is assigned the value of the expression e2, and so on sequentially; and then the value of this let expression is the value of the expression expr.\nAn add expression takes the form \"(add e1 e2)\" where add is always the string \"add\", there are always two expressions e1, e2 and the result is the addition of the evaluation of e1 and the evaluation of e2.\nA mult expression takes the form \"(mult e1 e2)\" where mult is always the string \"mult\", there are always two expressions e1, e2 and the result is the multiplication of the evaluation of e1 and the evaluation of e2.\nFor this question, we will use a smaller subset of variable names. A variable starts with a lowercase letter, then zero or more lowercase letters or digits. Additionally, for your convenience, the names \"add\", \"let\", and \"mult\" are protected and will never be used as variable names.\nFinally, there is the concept of scope. When an expression of a variable name is evaluated, within the context of that evaluation, the innermost scope (in terms of parentheses) is checked first for the value of that variable, and then outer scopes are checked sequentially. It is guaranteed that every expression is legal. Please see the examples for more details on the scope.\n\n \nExample 1:\n\nInput: expression = \"(let x 2 (mult x (let x 3 y 4 (add x y))))\"\nOutput: 14\nExplanation: In the expression (add x y), when checking for the value of the variable x,\nwe check from the innermost scope to the outermost in the context of the variable we are trying to evaluate.\nSince x = 3 is found first, the value of x is 3.\n\nExample 2:\n\nInput: expression = \"(let x 3 x 2 x)\"\nOutput: 2\nExplanation: Assignment in let statements is processed sequentially.\n\nExample 3:\n\nInput: expression = \"(let x 1 y 2 x (add x y) (add x y))\"\nOutput: 5\nExplanation: The first (add x y) evaluates as 3, and is assigned to x.\nThe second (add x y) evaluates as 3+2 = 5.\n\n \nConstraints:\n\n1 <= expression.length <= 2000\nThere are no leading or trailing spaces in expression.\nAll tokens are separated by a single space in expression.\nThe answer and all intermediate calculations of that answer are guaranteed to fit in a 32-bit integer.\nThe expression is guaranteed to be legal and evaluate to an integer.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

integers.\n\n0 means the cell is empty, so you can pass through,\n1 means the cell contains a cherry that you can pick up and pass through, or\n-1 means the cell contains a thorn that blocks your way.\n\nReturn the maximum number of cherries you can collect by following the rules below:\n\nStarting at the position (0, 0) and reaching (n - 1, n - 1) by moving right or down through valid path cells (cells with value 0 or 1).\nAfter reaching (n - 1, n - 1), returning to (0, 0) by moving left or up through valid path cells.\nWhen passing through a path cell containing a cherry, you pick it up, and the cell becomes an empty cell 0.\nIf there is no valid path between (0, 0) and (n - 1, n - 1), then no cherries can be collected.\n\n \nExample 1:\n\n\nInput: grid =

-{"question_id": 748, "task_id": "shortest-completing-word", "difficulty": "Easy", "problem_description": "Given a string licensePlate and an array of strings words, find the shortest completing word in words.\nA completing word is a word that contains all the letters in licensePlate. Ignore numbers and spaces in licensePlate, and treat letters as case insensitive. If a letter appears more than once in licensePlate, then it must appear in the word the same number of times or more.\nFor example, if licensePlate = \"aBc 12c\", then it contains letters 'a', 'b' (ignoring case), and 'c' twice. Possible completing words are \"abccdef\", \"caaacab\", and \"cbca\".\nReturn the shortest completing word in words. It is guaranteed an answer exists. If there are multiple shortest completing words, return the first one that occurs in words.\n \nExample 1:\n\nInput: licensePlate = \"1s3 PSt\", words = [\"step\",\"steps\",\"stripe\",\"stepple\"]\nOutput: \"steps\"\nExplanation: licensePlate contains letters 's', 'p', 's' (ignoring case), and 't'.\n\"step\" contains 't' and 'p', but only contains 1 's'.\n\"steps\" contains 't', 'p', and both 's' characters.\n\"stripe\" is missing an 's'.\n\"stepple\" is missing an 's'.\nSince \"steps\" is the only word containing all the letters, that is the answer.\n\nExample 2:\n\nInput: licensePlate = \"1s3 456\", words = [\"looks\",\"pest\",\"stew\",\"show\"]\nOutput: \"pest\"\nExplanation: licensePlate only contains the letter 's'. All the words contain 's', but among these \"pest\", \"stew\", and \"show\" are shortest. The answer is \"pest\" because it is the word that appears earliest of the 3.\n\n \nConstraints:\n\n1 <= licensePlate.length <= 7\nlicensePlate contains digits, letters (uppercase or lowercase), or space ' '.\n1 <= words.length <= 1000\n1 <= words[i].length <= 15\nwords[i] consists of lower case English letters.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n

-{"question_id": 749, "task_id": "contain-virus", "difficulty": "Hard", "problem_description": "A virus is spreading rapidly, and your task is to quarantine the infected area by installing walls.\nThe world is modeled as an m x n binary grid isInfected, where isInfected[i][j] == 0 represents uninfected cells, and isInfected[i][j] == 1 represents cells contaminated with the virus. A wall (and only one wall) can be installed between any two 4-directionally adjacent cells, on the shared boundary.\nEvery night, the virus spreads to all neighboring cells in all four directions unless blocked by a wall. Resources are limited. Each day, you can install walls around only one region (i.e., the affected area (continuous block of infected cells) that threatens the most uninfected cells the following night). There will never be a tie.\nReturn the number of walls used to quarantine all the infected regions. If the world will become fully infected, return the number of walls used.\n \nExample 1:\n\n\nInput: isInfected = [[0,1,0,0,0,0,0,1],[0,1,0,0,0,0,0,1],[0,0,0,0,0,0,0,1],[0,0,0,0,0,0,0,0]]\nOutput: 10\nExplanation: There are 2 contaminated regions.\nOn the first day, add 5 walls to quarantine the viral region on the left. The board after the virus spreads is:\n\nOn the second day, add 5 walls to quarantine the viral region on the right. The virus is fully contained.\n\n\nExample 2:\n\n\nInput: isInfected = [[1,1,1],[1,0,1],[1,1,1]]\nOutput: 4\nExplanation: Even though there is only one cell saved, there are 4 walls built.\nNotice that walls are only built on the shared boundary of two different cells.\n\nExample 3:\n\nInput: isInfected = [[1,1,1,0,0,0,0,0,0],[1,0,1,0,1,1,1,1,1],[1,1,1,0,0,0,0,0,0]]\nOutput: 13\nExplanation: The region on the left only builds two new walls.\n\n \nConstraints:\n\nm == isInfected.length\nn == isInfected[i].length\n1 <= m, n <= 50\nisInfected[i][j] is either 0 or 1.\nThere is always a contiguous viral region throughout the described process that will infect strictly more uncontaminated squares in the next round.\n\n", "canonical_tests": {"language": "python", "source": "def

-{"question_id": 752, "task_id": "open-the-lock", "difficulty": "Medium", "problem_description": "You have a lock in front of you with 4 circular wheels. Each wheel has 10 slots: '0', '1', '2', '3', '4', '5', '6', '7', '8', '9'. The wheels can rotate freely and wrap around: for example we can turn '9' to be '0', or '0' to be '9'. Each move consists of turning one wheel one slot.\nThe lock initially starts at '0000', a string representing the state of the 4 wheels.\nYou are given a list of deadends dead ends, meaning if the lock displays any of these codes, the wheels of the lock will stop turning and you will be unable to open it.\nGiven a target representing the value of the wheels that will unlock the lock, return the minimum total number of turns required to open the lock, or -1 if it is impossible.\n \nExample 1:\n\nInput: deadends = [\"0201\",\"0101\",\"0102\",\"1212\",\"2002\"], target = \"0202\"\nOutput: 6\nExplanation: \nA sequence of valid moves would be \"0000\" -> \"1000\" -> \"1100\" -> \"1200\" -> \"1201\" -> \"1202\" -> \"0202\".\nNote that a sequence like \"0000\" -> \"0001\" -> \"0002\" -> \"0102\" -> \"0202\" would be invalid,\nbecause the wheels of the lock become stuck after the display becomes the dead end \"0102\".\n\nExample 2:\n\nInput: deadends = [\"8888\"], target = \"0009\"\nOutput: 1\nExplanation: We can turn the last wheel in reverse to move from \"0000\" -> \"0009\".\n\nExample 3:\n\nInput: deadends = [\"8887\",\"8889\",\"8878\",\"8898\",\"8788\",\"8988\",\"7888\",\"9888\"], target = \"8888\"\nOutput: -1\nExplanation: We cannot reach the target without getting stuck.\n\n \nConstraints:\n\n1 <= deadends.length <= 500\ndeadends[i].length == 4\ntarget.length == 4\ntarget will not be in the list deadends.\ntarget and deadends[i] consist of digits only.\n\n", "canonical_tests": {"language":

Two strings are consecutive if the last character of the first string is exactly one index before the first character of the second string.\nReturn the lexicographically largest resulting string possible after applying the mentioned operations on the string.\n \nExample 1:\n\nInput: s = \"11011000\"\nOutput: \"11100100\"\nExplanation: The strings \"10\" [occuring at s[1]] and \"1100\" [at s[3]] are swapped.\nThis is the lexicographically largest string possible after some number of swaps.\n\nExample 2:\n\nInput: s = \"10\"\nOutput: \"10\"\n\n \nConstraints:\n\n1 <= s.length <= 50\ns[i]

At time t, the depth of the water everywhere is t. You can swim from a square to another 4-directionally adjacent square if and only if the elevation of both squares individually are at most t. You can swim infinite distances in zero time. Of course, you must stay within the boundaries of the grid during your swim.\nReturn the least time until you can reach the bottom right square (n - 1, n - 1) if you start at the top left square (0, 0).\n \nExample 1:\n\n\nInput: grid = [[0,2],[1,3]]\nOutput: 3\nExplanation:\nAt time 0, you are in grid location (0, 0).\nYou cannot go anywhere else because 4-directionally adjacent neighbors have a higher elevation than t = 0.\nYou cannot reach point (1, 1) until time 3.\nWhen the depth of water is 3, we can swim anywhere inside the grid.\n\nExample 2:\n\n\nInput: grid =

-{"question_id": 785, "task_id": "is-graph-bipartite", "difficulty": "Medium", "problem_description": "There is an undirected graph with n nodes, where each node is numbered between 0 and n - 1. You are given a 2D array graph, where graph[u] is an array of nodes that node u is adjacent to. More formally, for each v in graph[u], there is an undirected edge between node u and node v. The graph has the following properties:\n\nThere are no self-edges (graph[u] does not contain u).\nThere are no parallel edges (graph[u] does not contain duplicate values).\nIf v is in graph[u], then u is in graph[v] (the graph is undirected).\nThe graph may not be connected, meaning there may be two nodes u and v such that there is no path between them.\n\nA graph is bipartite if the nodes can be partitioned into two independent sets A and B such that every edge in the graph connects a node in set A and a node in set B.\nReturn true if and only if it is bipartite.\n \nExample 1:\n\n\nInput: graph = [[1,2,3],[0,2],[0,1,3],[0,2]]\nOutput: false\nExplanation: There is no way to partition the nodes into two independent sets such that every edge connects a node in one and a node in the other.\nExample 2:\n\n\nInput: graph = [[1,3],[0,2],[1,3],[0,2]]\nOutput: true\nExplanation: We can partition the nodes into two sets: {0, 2} and {1, 3}.\n \nConstraints:\n\ngraph.length == n\n1 <= n <= 100\n0 <= graph[u].length < n\n0 <= graph[u][i] <= n - 1\ngraph[u] does not contain u.\nAll the values of graph[u] are unique.\nIf graph[u] contains v, then graph[v] contains u.\n\n",

You start at the point [0, 0], and you are given a destination point target = [xtarget, ytarget] that you are trying to get to. There are several ghosts on the map with their starting positions given as a 2D array ghosts, where ghosts[i] = [xi, yi] represents the starting position of the ith ghost. All inputs are integral coordinates.\nEach turn, you and all the ghosts may independently choose to either move 1 unit in any of the four cardinal directions: north, east, south, or west, or stay still.

-{"question_id": 798, "task_id": "smallest-rotation-with-highest-score", "difficulty": "Hard", "problem_description": "You are given an array nums. You can rotate it by a non-negative integer k so that the array becomes [nums[k], nums[k + 1], ... nums[nums.length - 1], nums[0], nums[1], ..., nums[k-1]]. Afterward, any entries that are less than or equal to their index are worth one point.\n\nFor example, if we have nums = [2,4,1,3,0], and we rotate by k = 2, it becomes [1,3,0,2,4]. This is worth 3 points because 1 > 0 [no points], 3 > 1 [no points], 0 <= 2 [one point], 2 <= 3 [one point], 4 <= 4 [one point].\n\nReturn the rotation index k that corresponds to the highest score we can achieve if we rotated nums by it. If there are multiple answers, return the smallest such index k.\n \nExample 1:\n\nInput: nums = [2,3,1,4,0]\nOutput: 3\nExplanation: Scores for each k are listed below: \nk = 0, nums = [2,3,1,4,0], score 2\nk = 1, nums = [3,1,4,0,2], score 3\nk = 2, nums = [1,4,0,2,3], score 3\nk = 3, nums = [4,0,2,3,1], score 4\nk = 4, nums = [0,2,3,1,4], score 3\nSo we should choose k = 3, which has the highest score.\n\nExample 2:\n\nInput: nums = [1,3,0,2,4]\nOutput: 0\nExplanation: nums will always have 3 points no matter how it shifts.\nSo we will choose the smallest k, which is 0.\n\n

-{"question_id": 803, "task_id": "bricks-falling-when-hit", "difficulty": "Hard", "problem_description": "You are given an m x n binary grid, where each 1 represents a brick and 0 represents an empty space. A brick is stable if:\n\nIt is directly connected to the top of the grid, or\nAt least one other brick in its four adjacent cells is stable.\n\nYou are also given an array hits, which is a sequence of erasures we want to apply. Each time we want to erase the brick at the location hits[i] = (rowi, coli). The brick on that location (if it exists) will disappear. Some other bricks may no longer be stable because of that erasure and will fall. Once a brick falls, it is immediately erased from the grid (i.e., it does not land on other stable bricks).\nReturn an array result, where each result[i] is the number of bricks that will fall after the ith erasure is applied.\nNote that an erasure may refer to a location with no brick, and if it does, no bricks drop.\n \nExample 1:\n\nInput: grid = [[1,0,0,0],[1,1,1,0]], hits = [[1,0]]\nOutput: [2]\nExplanation: Starting with the grid:\n[[1,0,0,0],\n [1,1,1,0]]\nWe erase the underlined brick at (1,0), resulting in the grid:\n[[1,0,0,0],\n [0,1,1,0]]\nThe two underlined bricks are no longer stable as they are no longer connected to the top nor adjacent to another stable brick, so they will fall. The resulting grid is:\n[[1,0,0,0],\n [0,0,0,0]]\nHence the result is [2].\n\nExample 2:\n\nInput: grid = [[1,0,0,0],[1,1,0,0]], hits = [[1,1],[1,0]]\nOutput: [0,0]\nExplanation: Starting with the grid:\n[[1,0,0,0],\n [1,1,0,0]]\nWe erase the underlined brick at (1,1), resulting in the grid:\n[[1,0,0,0],\n [1,0,0,0]]\nAll remaining bricks are still stable, so no bricks fall. The grid remains the same:\n[[1,0,0,0],\n [1,0,0,0]]\nNext, we erase the underlined brick at (1,0), resulting in the grid:\n[[1,0,0,0],\n [0,0,0,0]]\nOnce again, all remaining bricks are still stable, so no bricks fall.\nHence the result is [0,0].\n\n \nConstraints:\n\nm == grid.length\nn == grid[i].length\n1 <= m, n <= 200\ngrid[i][j] is 0 or 1.\n1 <= hits.length <= 4 * 104\nhits[i].length == 2\n0

Specifically, widths[0] is the width of 'a', widths[1] is the width of 'b', and so on.\nYou are trying to write s across several lines, where each line is no longer than 100 pixels. Starting at the beginning of s, write as many letters on the first line such that the total width does not exceed 100 pixels. Then, from where you stopped in s, continue writing as many letters as you can on the second line.

You are given a 0-indexed n x n integer matrix grid where grid[r][c] represents the height of the building located in the block at row r and column c.\nA city's skyline is the outer contour formed by all the building when viewing the side of the city from a distance. The skyline from each cardinal direction north, east, south, and west may be different.\nWe are allowed to increase the height of any number of buildings by any amount (the amount can be different per building). The height of a 0-height building can also be increased. However, increasing the height of a building should not affect the city's skyline from any cardinal direction.\nReturn the maximum total sum that the height of the buildings can be increased by without changing the city's skyline from any cardinal direction.\n \nExample 1:\n\n\nInput: grid = [[3,0,8,4],[2,4,5,7],[9,2,6,3],[0,3,1,0]]\nOutput: 35\nExplanation: The building heights are shown in the center of the above image.\nThe skylines when viewed from each cardinal direction are drawn in red.\nThe grid after increasing the height of buildings without affecting skylines is:\ngridNew = [ [8, 4, 8, 7],\n [7, 4, 7, 7],\n [9, 4, 8, 7],\n [3, 3, 3, 3] ]\n\nExample 2:\n\nInput: grid = [[0,0,0],[0,0,0],[0,0,0]]\nOutput: 0\nExplanation: Increasing the height of any building will result in the skyline changing.\n\n \nConstraints:\n\nn == grid.length\nn == grid[r].length\n2 <= n <= 50\n0 <= grid[r][c] <= 100\n\n", "canonical_tests": {"language": "python", "source": "def

-{"question_id": 811, "task_id": "subdomain-visit-count", "difficulty": "Medium", "problem_description": "A website domain \"discuss.leetcode.com\" consists of various subdomains. At the top level, we have \"com\", at the next level, we have \"leetcode.com\" and at the lowest level, \"discuss.leetcode.com\". When we visit a domain like \"discuss.leetcode.com\", we will also visit the parent domains \"leetcode.com\" and \"com\" implicitly.\nA count-paired domain is a domain that has one of the two formats \"rep d1.d2.d3\" or \"rep d1.d2\" where rep is the number of visits to the domain and d1.d2.d3 is the domain itself.\n\nFor example, \"9001 discuss.leetcode.com\" is a count-paired domain that indicates that discuss.leetcode.com was visited 9001 times.\n\nGiven an array of count-paired domains cpdomains, return an array of the count-paired domains of each subdomain in the input. You may return the answer in any order.\n \nExample 1:\n\nInput: cpdomains = [\"9001 discuss.leetcode.com\"]\nOutput: [\"9001 leetcode.com\",\"9001 discuss.leetcode.com\",\"9001 com\"]\nExplanation: We only have one website domain: \"discuss.leetcode.com\".\nAs discussed above, the subdomain \"leetcode.com\" and \"com\" will also be visited. So they will all be visited 9001 times.\n\nExample 2:\n\nInput: cpdomains = [\"900 google.mail.com\", \"50 yahoo.com\", \"1 intel.mail.com\", \"5 wiki.org\"]\nOutput: [\"901 mail.com\",\"50 yahoo.com\",\"900 google.mail.com\",\"5 wiki.org\",\"5 org\",\"1 intel.mail.com\",\"951 com\"]\nExplanation: We will visit \"google.mail.com\" 900 times, \"yahoo.com\" 50 times, \"intel.mail.com\" once and \"wiki.org\" 5 times.\nFor the subdomains, we will visit \"mail.com\" 900 + 1 = 901 times, \"com\" 900 + 50 + 1 = 951 times, and \"org\" 5 times.\n\n \nConstraints:\n\n1 <= cpdomain.length <= 100\n1 <= cpdomain[i].length <= 100\ncpdomain[i] follows either the \"repi d1i.d2i.d3i\" format or the \"repi d1i.d2i\" format.\nrepi is an integer in the range [1, 104].\nd1i, d2i, and d3i consist of lowercase English letters.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(cpdomains = ['1 x.y.z', '2 y.z', '3 z']) == ['1 x.y.z', '3 y.z', '6 z']\n

-{"question_id": 813, "task_id": "largest-sum-of-averages", "difficulty": "Medium", "problem_description": "You are given an integer array nums and an integer k. You can partition the array into at most k non-empty adjacent subarrays. The score of a partition is the sum of the averages of each subarray.\nNote that the partition must use every integer in nums, and that the score is not necessarily an integer.\nReturn the maximum score you can achieve of all the possible partitions. Answers within 10-6 of the actual answer will be accepted.\n \nExample 1:\n\nInput: nums = [9,1,2,3,9], k = 3\nOutput: 20.00000\nExplanation: \nThe best choice is to partition nums into [9], [1, 2, 3], [9]. The answer is 9 + (1 + 2 + 3) / 3 + 9 = 20.\nWe could have also partitioned nums into [9, 1], [2], [3, 9], for example.\nThat partition would lead to a score of 5 + 2 + 6 = 13, which is worse.\n\nExample 2:\n\nInput: nums = [1,2,3,4,5,6,7], k = 4\nOutput: 20.50000\n\n \nConstraints:\n\n1 <= nums.length <= 100\n1 <= nums[i] <= 104\n1 <= k <= nums.length\n\n", "canonical_tests":

Initially, each card is placed on a table such that the front number is facing up and the other is facing down. You may flip over any number of cards (possibly zero).\nAfter flipping the cards, an integer is considered good if it is facing down on some card and not facing up on any card.\nReturn the minimum possible good integer after flipping the cards. If there are no good integers, return 0.\n \nExample 1:\n\nInput: fronts = [1,2,4,4,7], backs = [1,3,4,1,3]\nOutput: 2\nExplanation:\nIf we flip the second card, the face up numbers are [1,3,4,4,7] and the face down are [1,2,4,1,3].\n2 is the minimum good integer as it appears facing down but not facing up.\nIt can be shown that 2 is the minimum possible good integer obtainable after flipping some cards.\n\nExample 2:\n\nInput: fronts = [1], backs = [1]\nOutput: 0\nExplanation:\nThere are no good integers no matter how we flip the cards, so we return 0.\n\n \nConstraints:\n\nn ==

Each word consists of lowercase and uppercase letters only.\nWe would like to convert the sentence to \"Goat Latin\" (a made-up language similar to Pig Latin.) The rules of Goat Latin are as follows:\n\nIf a word begins with a vowel ('a', 'e', 'i', 'o', or 'u'), append \"ma\" to the end of the word.\n\n\t\nFor example, the word \"apple\" becomes \"applema\".\n\n\nIf a word begins with a consonant (i.e., not a vowel), remove the first letter and append it to the end, then add \"ma\".\n\t\nFor example, the word \"goat\" becomes \"oatgma\".\n\n\nAdd one letter 'a' to the end of each word per its word index in the sentence, starting with 1.\n\t\nFor example, the first word gets \"a\" added to the end, the second word gets \"aa\" added to the end, and so on.\n\n\n\nReturn the final sentence representing the conversion from sentence to Goat Latin.\n \nExample 1:\nInput: sentence = \"I speak Goat Latin\"\nOutput: \"Imaa

-{"question_id": 831, "task_id": "masking-personal-information", "difficulty": "Medium", "problem_description": "You are given a personal information string s, representing either an email address or a phone number. Return the masked personal information using the below rules.\nEmail address:\nAn email address is:\n\nA name consisting of uppercase and lowercase English letters, followed by\nThe '@' symbol, followed by\nThe domain consisting of uppercase and lowercase English letters with a dot '.' somewhere in the middle (not the first or last character).\n\nTo mask an email:\n\nThe uppercase letters in the name and domain must be converted to lowercase letters.\nThe middle letters of the name (i.e., all but the first and last letters) must be replaced by 5 asterisks \"*****\".\n\nPhone number:\nA phone number is formatted as follows:\n\nThe phone number contains 10-13 digits.\nThe last 10 digits make up the local number.\nThe remaining 0-3 digits, in the beginning, make up the country code.\nSeparation characters from the set {'+', '-', '(', ')', ' '} separate the above digits in some way.\n\nTo mask a phone number:\n\nRemove all separation characters.\nThe masked phone number should have the form:\n\t\n\"***-***-XXXX\" if the country code has 0 digits.\n\"+*-***-***-XXXX\" if the country code has 1 digit.\n\"+**-***-***-XXXX\" if the country code has 2 digits.\n\"+***-***-***-XXXX\" if the country code has 3 digits.\n\n\n\"XXXX\" is the last 4 digits of the local number.\n\n \nExample 1:\n\nInput: s = \"LeetCode@LeetCode.com\"\nOutput:

\"AB@qq.com\"\nOutput: \"a*****b@qq.com\"\nExplanation: s is an email address.\nThe name and domain are converted to lowercase, and the middle of the name is replaced by 5 asterisks.\nNote that even though \"ab\" is 2 characters, it still must have 5 asterisks in the middle.\n\nExample 3:\n\nInput: s = \"1(234)567-890\"\nOutput: \"***-***-7890\"\nExplanation: s is a phone number.\nThere are 10 digits, so the local number is 10 digits and the country code is 0 digits.\nThus, the resulting masked number is \"***-***-7890\".\n\n \nConstraints:\n\ns is either a valid email or a phone

resulting image.\nTo flip an image horizontally means that each row of the image is reversed.\n\nFor example, flipping [1,1,0] horizontally results in [0,1,1].\n\nTo invert an image means that each 0 is replaced by 1, and each 1 is replaced by 0.\n\nFor example, inverting [0,1,1] results in [1,0,0].\n\n \nExample 1:\n\nInput: image = [[1,1,0],[1,0,1],[0,0,0]]\nOutput: [[1,0,0],[0,1,0],[1,1,1]]\nExplanation: First reverse each row: [[0,1,1],[1,0,1],[0,0,0]].\nThen, invert the image: [[1,0,0],[0,1,0],[1,1,1]]\n\nExample 2:\n\nInput: image = [[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]]\nOutput: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\nExplanation: First reverse each row: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]].\nThen invert the image:

The replacement operations are given as three 0-indexed parallel arrays, indices, sources, and targets, all of length k.\nTo complete the ith replacement operation:\n\nCheck if the substring sources[i] occurs at index indices[i] in the original string s.\nIf it does not occur, do nothing.\nOtherwise if it does occur, replace that substring with targets[i].\n\nFor example, if s = \"abcd\", indices[i] = 0, sources[i] = \"ab\", and targets[i] = \"eee\", then the result of this replacement will be \"eeecd\".\nAll replacement operations must occur simultaneously, meaning the replacement operations should not affect the indexing of each other. The testcases will be generated such that the replacements will not overlap.\n\nFor example, a testcase with s = \"abc\", indices = [0, 1], and sources = [\"ab\",\"bc\"] will not be generated because the \"ab\" and \"bc\" replacements overlap.\n\nReturn the resulting string after performing all replacement operations on s.\nA substring is a contiguous sequence of characters in a string.\n \nExample 1:\n\n\nInput: s = \"abcd\", indices = [0, 2], sources = [\"a\", \"cd\"], targets = [\"eee\", \"ffff\"]\nOutput: \"eeebffff\"\nExplanation:\n\"a\" occurs at index 0 in s, so we replace it with \"eee\".\n\"cd\" occurs at index 2 in s, so we replace it with \"ffff\".\n\nExample 2:\n\n\nInput: s = \"abcd\", indices = [0, 2], sources = [\"ab\",\"ec\"], targets = [\"eee\",\"ffff\"]\nOutput: \"eeecd\"\nExplanation:\n\"ab\" occurs at index 0 in s, so we replace it with \"eee\".\n\"ec\" does not occur at index 2 in s, so we do nothing.\n\n \nConstraints:\n\n1 <= s.length <= 1000\nk == indices.length == sources.length == targets.length\n1 <= k <= 100\n0 <= indexes[i] < s.length\n1 <= sources[i].length, targets[i].length <= 50\ns consists of only lowercase English

A binary matrix has only 0s and 1s as values.\nWe translate one image however we choose by sliding all the 1 bits left, right, up, and/or down any number of units. We then place it on top of the other image. We can then calculate the overlap by counting the number of positions that have a 1 in both images.\nNote also that a translation does not include any kind of rotation. Any 1 bits that are translated outside of the matrix borders are erased.\nReturn the largest possible overlap.\n \nExample 1:\n\n\nInput: img1 = [[1,1,0],[0,1,0],[0,1,0]], img2 = [[0,0,0],[0,1,1],[0,0,1]]\nOutput: 3\nExplanation: We translate img1 to right by 1 unit and down by 1 unit.\n\nThe number of positions that have a 1 in both images is 3 (shown in red).\n\n\nExample

Notice that \"tars\" and \"arts\" are in the same group even though they are not similar. Formally, each group is such that a word is in the group if and only if it is similar to at least one other word in the group.\nWe are given a list strs of strings where every string in strs is an anagram of every other string in strs. How many groups are there?\n \nExample 1:\n\nInput: strs = [\"tars\",\"rats\",\"arts\",\"star\"]\nOutput: 2\n\nExample 2:\n\nInput: strs = [\"omv\",\"ovm\"]\nOutput: 1\n\n \nConstraints:\n\n1 <= strs.length <= 300\n1 <= strs[i].length <= 300\nstrs[i] consists of lowercase letters only.\nAll words in strs have the same length and are anagrams of each other.\n\n", "canonical_tests":

a person sitting in the ith seat, and seats[i] = 0 represents that the ith seat is empty (0-indexed).\nThere is at least one empty seat, and at least one person sitting.\nAlex wants to sit in the seat such that the distance between him and the closest person to him is maximized. \nReturn that maximum distance to the closest person.\n \nExample 1:\n\n\nInput: seats = [1,0,0,0,1,0,1]\nOutput: 2\nExplanation: \nIf Alex sits in the second open seat (i.e. seats[2]), then the closest person has distance 2.\nIf Alex sits in any other open seat, the closest person has distance 1.\nThus, the maximum distance to the closest person is 2.\n\nExample 2:\n\nInput: seats = [1,0,0,0]\nOutput: 3\nExplanation: \nIf Alex sits in the last seat (i.e. seats[3]), the closest person is 3 seats away.\nThis is the maximum distance possible, so the answer is 3.\n\nExample 3:\n\nInput: seats = [0,1]\nOutput: 1\n\n \nConstraints:\n\n2 <= seats.length <= 2 * 104\nseats[i] is 0 or 1.\nAt least one

Each rectangle[i] = [xi1, yi1, xi2, yi2] denotes the ith rectangle where (xi1, yi1) are the coordinates of the bottom-left corner, and (xi2, yi2) are the coordinates of the top-right corner.\nCalculate the total area covered by all rectangles in the plane. Any area covered by two or more rectangles should only be counted once.\nReturn the total area. Since the answer may be too large, return it modulo 109 + 7.\n \nExample 1:\n\n\nInput: rectangles = [[0,0,2,2],[1,0,2,3],[1,0,3,1]]\nOutput: 6\nExplanation: A total area of 6 is covered by all three rectangles, as illustrated in the picture.\nFrom (1,1) to (2,2), the green and red rectangles overlap.\nFrom (1,0) to (2,3), all three rectangles overlap.\n\nExample 2:\n\nInput: rectangles =

The speed of the car fleet is the minimum speed of any car in the fleet.\nIf a car catches up to a car fleet at the mile target, it will still be considered as part of the car fleet.\nReturn the number of car fleets that will arrive at the destination.\n \nExample 1:\n\nInput: target = 12, position = [10,8,0,5,3], speed = [2,4,1,1,3]\nOutput: 3\nExplanation:\n\nThe cars starting at 10 (speed 2) and 8 (speed 4) become a fleet, meeting each other at 12. The fleet forms at target.\nThe car starting at 0 (speed 1) does not catch up to any other car, so it is a fleet by itself.\nThe cars starting at 5 (speed 1) and 3 (speed 3) become a fleet, meeting each other at 6. The fleet moves at speed 1 until it reaches target.\n\n\nExample 2:\n\nInput: target = 10, position = [3], speed = [3]\nOutput: 1\nExplanation:\nThere is only one car, hence there is only one fleet.\nExample 3:\n\nInput: target = 100, position = [0,2,4], speed = [4,2,1]\nOutput: 1\nExplanation:\n\nThe cars starting at 0 (speed 4) and 2 (speed 2) become a fleet, meeting each other at 4. The car starting at 4 (speed 1) travels to 5.\nThen, the fleet at 4 (speed 2) and the car at position 5 (speed 1) become one fleet, meeting each other at 6. The fleet moves at speed 1 until it reaches target.\n\n\n \nConstraints:\n\nn == position.length == speed.length\n1 <= n <= 105\n0 < target <= 106\n0 <= position[i] < target\nAll the values of

-{"question_id": 860, "task_id": "lemonade-change", "difficulty": "Easy", "problem_description": "At a lemonade stand, each lemonade costs $5. Customers are standing in a queue to buy from you and order one at a time (in the order specified by bills). Each customer will only buy one lemonade and pay with either a $5, $10, or $20 bill. You must provide the correct change to each customer so that the net transaction is that the customer pays $5.\nNote that you do not have any change in hand at first.\nGiven an integer array bills where bills[i] is the bill the ith customer pays, return true if you can provide every customer with the correct change, or false otherwise.\n \nExample 1:\n\nInput: bills = [5,5,5,10,20]\nOutput: true\nExplanation: \nFrom the first 3 customers, we collect three $5 bills in order.\nFrom the fourth customer, we collect a $10 bill and give back a $5.\nFrom the fifth customer, we give a $10 bill and a $5 bill.\nSince all customers got correct change, we output true.\n\nExample 2:\n\nInput: bills = [5,5,10,10,20]\nOutput: false\nExplanation: \nFrom the first two customers in order, we collect two $5 bills.\nFor the next two customers in order, we collect a $10 bill and give back a $5 bill.\nFor the last customer, we can not give the change of $15 back because we only have two $10 bills.\nSince not every customer received the correct change, the answer is false.\n\n \nConstraints:\n\n1 <= bills.length <= 105\nbills[i] is either 5, 10, or 20.\n\n", "canonical_tests":

The gas stations are represented as an array stations where stations[i] = [positioni, fueli] indicates that the ith gas station is positioni miles east of the starting position and has fueli liters of gas.\nThe car starts with an infinite tank of gas, which initially has startFuel liters of fuel in it. It uses one liter of gas per one mile that it drives. When the car reaches a gas station, it may stop and refuel, transferring all the gas from the station into the car.\nReturn the minimum number of refueling stops the car must make in order to reach its destination. If it cannot reach the destination, return -1.\nNote that if the car reaches a gas station with 0 fuel left, the car can still refuel there. If the car reaches the destination with 0 fuel left, it is still considered to have arrived.\n \nExample 1:\n\nInput: target = 1, startFuel = 1, stations = []\nOutput: 0\nExplanation: We can reach the target without refueling.\n\nExample 2:\n\nInput: target = 100, startFuel = 1, stations = [[10,100]]\nOutput: -1\nExplanation: We can not reach the target (or even the first gas station).\n\nExample 3:\n\nInput: target = 100, startFuel = 10, stations = [[10,60],[20,30],[30,30],[60,40]]\nOutput: 2\nExplanation: We start with 10 liters of fuel.\nWe drive to position 10, expending 10 liters of fuel. We refuel from 0 liters to 60 liters of gas.\nThen, we drive from position 10 to position 60 (expending 50 liters of fuel),\nand refuel from 10 liters to 50 liters of gas. We then drive to and reach the target.\nWe made 2 refueling stops along the way, so we return 2.\n\n \nConstraints:\n\n1 <= target, startFuel <= 109\n0 <= stations.length <= 500\n1 <= positioni <

-{"question_id": 874, "task_id": "walking-robot-simulation", "difficulty": "Medium", "problem_description": "A robot on an infinite XY-plane starts at point (0, 0) facing north. The robot receives an array of integers commands, which represents a sequence of moves that it needs to execute. There are only three possible types of instructions the robot can receive:\n\n-2: Turn left 90 degrees.\n-1: Turn right 90 degrees.\n1 <= k <= 9: Move forward k units, one unit at a time.\n\nSome of the grid squares are obstacles. The ith obstacle is at grid point obstacles[i] = (xi, yi). If the robot runs into an obstacle, it will stay in its current location (on the block adjacent to the obstacle) and move onto the next command.\nReturn the maximum squared Euclidean distance that the robot reaches at any point in its path (i.e. if the distance is 5, return 25).\nNote:\n\nThere can be an obstacle at (0, 0). If this happens, the robot will ignore the obstacle until it has moved off the origin. However, it will be unable to return to (0, 0) due to the obstacle.\nNorth means +Y direction.\nEast means +X direction.\nSouth means -Y direction.\nWest means -X direction.\n\n \nExample 1:\n\nInput: commands = [4,-1,3], obstacles = []\nOutput: 25\nExplanation: \nThe robot starts at (0, 0):\n\nMove north 4 units to (0, 4).\nTurn right.\nMove east 3 units to (3, 4).\n\nThe furthest point the robot ever gets from the origin is (3, 4), which squared is 32 + 42 = 25 units away.\n\nExample 2:\n\nInput: commands = [4,-1,4,-2,4], obstacles = [[2,4]]\nOutput: 65\nExplanation:\nThe robot starts at (0, 0):\n\nMove north 4 units to (0, 4).\nTurn right.\nMove east 1 unit and get blocked by the obstacle at (2, 4), robot is at (1, 4).\nTurn left.\nMove north 4 units to (1, 8).\n\nThe furthest point the robot ever gets from the origin is (1, 8), which squared is 12 + 82 = 65 units away.\n\nExample 3:\n\nInput: commands = [6,-1,-1,6], obstacles = [[0,0]]\nOutput: 36\nExplanation:\nThe robot starts at (0, 0):\n\nMove north 6 units to (0, 6).\nTurn right.\nTurn right.\nMove south 5 units and get blocked by the obstacle at (0,0), robot is at (0, 1).\n\nThe furthest point the robot ever gets from the origin is (0, 6), which squared is 62 = 36 units away.\n\n \nConstraints:\n\n1 <= commands.length <= 104\ncommands[i] is either -2, -1, or an integer in the range [1, 9].\n0 <= obstacles.length <= 104\n-3 * 104 <= xi, yi <= 3 * 104\nThe answer is guaranteed to be less than 231.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(commands = [5, -2,

-{"question_id": 877, "task_id": "stone-game", "difficulty": "Medium", "problem_description": "Alice and Bob play a game with piles of stones. There are an even number of piles arranged in a row, and each pile has a positive integer number of stones piles[i].\nThe objective of the game is to end with the most stones. The total number of stones across all the piles is odd, so there are no ties.\nAlice and Bob take turns, with Alice starting first. Each turn, a player takes the entire pile of stones either from the beginning or from the end of the row. This continues until there are no more piles left, at which point the person with the most stones wins.\nAssuming Alice and Bob play optimally, return true if Alice wins the game, or false if Bob wins.\n \nExample 1:\n\nInput: piles = [5,3,4,5]\nOutput: true\nExplanation: \nAlice starts first, and can only take the first 5 or the last 5.\nSay she takes the first 5, so that the row becomes [3, 4, 5].\nIf Bob takes 3, then the board is [4, 5], and Alice takes 5 to win with 10 points.\nIf Bob takes the last 5, then the board is [3, 4], and Alice takes 4 to win with 9 points.\nThis demonstrated that taking the first 5 was a winning move for Alice, so we return true.\n\nExample 2:\n\nInput: piles = [3,7,2,3]\nOutput: true\n\n \nConstraints:\n\n2 <= piles.length <= 500\npiles.length is even.\n1 <= piles[i] <= 500\nsum(piles[i]) is odd.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(piles = [15, 30, 5, 10, 20,

The ith crime generates a profit[i] and requires group[i] members to participate in it. If a member participates in one crime, that member can't participate in another crime.\nLet's call a profitable scheme any subset of these crimes that generates at least minProfit profit, and the total number of members participating in that subset of crimes is at most n.\nReturn the number of schemes that can be chosen. Since the answer may be very large, return it modulo 109 + 7.\n \nExample 1:\n\nInput: n = 5, minProfit = 3, group = [2,2], profit = [2,3]\nOutput: 2\nExplanation: To make a profit of at least 3, the group could either commit crimes 0 and 1, or just crime 1.\nIn total, there are 2 schemes.\nExample 2:\n\nInput: n = 10, minProfit = 5, group = [2,3,5], profit = [6,7,8]\nOutput: 7\nExplanation: To make a profit of at least 5, the group could commit any crimes, as long as they commit one.\nThere are 7 possible schemes: (0), (1), (2), (0,1), (0,2), (1,2), and (0,1,2).\n \nConstraints:\n\n1 <= n

You decide to subdivide each edge in the graph into a chain of nodes, with the number of new nodes varying between each edge.\nThe graph is given as a 2D array of edges where edges[i] = [ui, vi, cnti] indicates that there is an edge between nodes ui and vi in the original graph, and cnti is the total number of new nodes that you will subdivide the edge into. Note that cnti == 0 means you will not subdivide the edge.\nTo subdivide the edge [ui, vi], replace it with (cnti + 1) new edges and cnti new nodes. The new nodes are x1, x2, ..., xcnti, and the new edges are [ui, x1], [x1, x2], [x2, x3], ..., [xcnti-1, xcnti], [xcnti, vi].\nIn this new graph, you want to know how many nodes are reachable from the node 0, where a node is reachable if the distance is maxMoves or less.\nGiven the original graph and maxMoves, return the number of nodes that are reachable from node 0 in the new graph.\n \nExample 1:\n\n\nInput: edges = [[0,1,10],[0,2,1],[1,2,2]], maxMoves = 6, n = 3\nOutput: 13\nExplanation: The edge subdivisions are shown in the image above.\nThe nodes that are reachable are highlighted in yellow.\n\nExample 2:\n\nInput: edges = [[0,1,4],[1,2,6],[0,2,8],[1,3,1]], maxMoves = 10, n = 4\nOutput: 23\n\nExample 3:\n\nInput: edges = [[1,2,4],[1,4,5],[1,3,1],[2,3,4],[3,4,5]], maxMoves = 17, n = 5\nOutput: 1\nExplanation: Node 0 is disconnected from the rest of the graph, so only node 0 is reachable.\n\n \nConstraints:\n\n0 <= edges.length <= min(n * (n - 1) / 2, 104)\nedges[i].length == 3\n0 <= ui < vi < n\nThere are no multiple edges in the graph.\n0 <= cnti <= 104\n0 <= maxMoves <= 109\n1 <= n <= 3000\n\n", "canonical_tests": {"language": "python", "source": "def

You may return the answer in any order.\nA word matches the pattern if there exists a permutation of letters p so that after replacing every letter x in the pattern with p(x), we get the desired word.\nRecall that a permutation of letters is a bijection from letters to letters: every letter maps to another letter, and no two letters map to the same letter.\n \nExample 1:\n\nInput: words = [\"abc\",\"deq\",\"mee\",\"aqq\",\"dkd\",\"ccc\"], pattern = \"abb\"\nOutput: [\"mee\",\"aqq\"]\nExplanation: \"mee\" matches the pattern because there is a permutation {a -> m, b -> e, ...}. \n\"ccc\" does not match the pattern because {a -> c, b -> c, ...} is not a permutation, since a and b map to the same letter.\n\nExample 2:\n\nInput: words = [\"a\",\"b\",\"c\"], pattern = \"a\"\nOutput: [\"a\",\"b\",\"c\"]\n\n \nConstraints:\n\n1 <= pattern.length <= 20\n1 <= words.length <= 50\nwords[i].length == pattern.length\npattern and words[i] are lowercase English

can swap any two even indexed characters or any two odd indexed characters of a string words[i].\nTwo strings words[i] and words[j] are special-equivalent if after any number of moves, words[i] == words[j].\n\nFor example, words[i] = \"zzxy\" and words[j] = \"xyzz\" are special-equivalent because we may make the moves \"zzxy\" -> \"xzzy\" -> \"xyzz\".\n\nA group of special-equivalent strings from words is a non-empty subset of words such that:\n\nEvery pair of strings in the group are special equivalent, and\nThe group is the largest size possible (i.e., there is not a string words[i] not in the group such that words[i] is special-equivalent to every string in the group).\n\nReturn the number of groups of special-equivalent strings from words.\n \nExample 1:\n\nInput: words = [\"abcd\",\"cdab\",\"cbad\",\"xyzz\",\"zzxy\",\"zzyx\"]\nOutput: 3\nExplanation: \nOne group is [\"abcd\", \"cdab\", \"cbad\"], since they are all pairwise special equivalent, and none of the other strings is all pairwise special equivalent to these.\nThe other two groups are [\"xyzz\", \"zzxy\"] and [\"zzyx\"].\nNote that in particular, \"zzxy\" is not special equivalent to \"zzyx\".\n\nExample

-{"question_id": 904, "task_id": "fruit-into-baskets", "difficulty": "Medium", "problem_description": "You are visiting a farm that has a single row of fruit trees arranged from left to right. The trees are represented by an integer array fruits where fruits[i] is the type of fruit the ith tree produces.\nYou want to collect as much fruit as possible. However, the owner has some strict rules that you must follow:\n\nYou only have two baskets, and each basket can only hold a single type of fruit. There is no limit on the amount of fruit each basket can hold.\nStarting from any tree of your choice, you must pick exactly one fruit from every tree (including the start tree) while moving to the right. The picked fruits must fit in one of your baskets.\nOnce you reach a tree with fruit that cannot fit in your baskets, you must stop.\n\nGiven the integer array fruits, return the maximum number of fruits you can pick.\n \nExample 1:\n\nInput: fruits = [1,2,1]\nOutput: 3\nExplanation: We can pick from all 3 trees.\n\nExample 2:\n\nInput: fruits = [0,1,2,2]\nOutput: 3\nExplanation: We can pick from trees [1,2,2].\nIf we had started at the first tree, we would only pick from trees [0,1].\n\nExample 3:\n\nInput: fruits = [1,2,3,2,2]\nOutput: 4\nExplanation: We can pick from trees [2,3,2,2].\nIf we had started at the first tree, we would only pick from trees [1,2].\n\n \nConstraints:\n\n1 <= fruits.length <= 105\n0 <= fruits[i] < fruits.length\n\n", "canonical_tests":

-{"question_id": 909, "task_id": "snakes-and-ladders", "difficulty": "Medium", "problem_description": "You are given an n x n integer matrix board where the cells are labeled from 1 to n2 in a Boustrophedon style starting from the bottom left of the board (i.e. board[n - 1][0]) and alternating direction each row.\nYou start on square 1 of the board. In each move, starting from square curr, do the following:\n\nChoose a destination square next with a label in the range [curr + 1, min(curr + 6, n2)].\n\n\t\nThis choice simulates the result of a standard 6-sided die roll: i.e., there are always at most 6 destinations, regardless of the size of the board.\n\n\nIf next has a snake or ladder, you must move to the destination of that snake or ladder. Otherwise, you move to next.\nThe game ends when you reach the square n2.\n\nA board square on row r and column c has a snake or ladder if board[r][c] != -1. The destination of that snake or ladder is board[r][c]. Squares 1 and n2 are not the starting points of any snake or ladder.\nNote that you only take a snake or ladder at most once per dice roll. If the destination to a snake or ladder is the start of another snake or ladder, you do not follow the subsequent snake or ladder.\n\nFor example, suppose the board is [[-1,4],[-1,3]], and on the first move, your destination square is 2. You follow the ladder to square 3, but do not follow the subsequent ladder to 4.\n\nReturn the least number of dice rolls required to reach the square n2. If it is not possible to reach the square, return -1.\n \nExample 1:\n\n\nInput: board = [[-1,-1,-1,-1,-1,-1],[-1,-1,-1,-1,-1,-1],[-1,-1,-1,-1,-1,-1],[-1,35,-1,-1,13,-1],[-1,-1,-1,-1,-1,-1],[-1,15,-1,-1,-1,-1]]\nOutput: 4\nExplanation: \nIn the beginning, you start at square 1 (at row 5, column 0).\nYou decide to move to square 2 and must take the ladder to square 15.\nYou then decide to move to square 17 and must take the snake to square 13.\nYou then decide to move to square 14 and must take the ladder to square 35.\nYou then decide to move to square 36, ending the game.\nThis is the lowest possible number of moves to reach the last square, so return 4.\n\nExample 2:\n\nInput: board = [[-1,-1],[-1,3]]\nOutput: 1\n\n \nConstraints:\n\nn == board.length == board[i].length\n2 <= n <= 20\nboard[i][j] is either -1 or in the range [1, n2].\nThe squares labeled 1 and n2 are not

Besides lowercase letters, the email may contain one or more '.' or '+'.\n\nFor example, in \"alice@leetcode.com\", \"alice\" is the local name, and \"leetcode.com\" is the domain name.\n\nIf you add periods '.' between some characters in the local name part of an email address, mail sent there will be forwarded to the same address without dots in the local name. Note that this rule does not apply to domain names.\n\nFor example, \"alice.z@leetcode.com\" and \"alicez@leetcode.com\" forward to the same email address.\n\nIf you add a plus '+' in the local name, everything after the first plus sign will be ignored. This allows certain emails to be filtered. Note that this rule does not apply to domain names.\n\nFor example, \"m.y+name@email.com\" will be forwarded to \"my@email.com\".\n\nIt is possible to use both of these rules at the same time.\nGiven

Each log is a space-delimited string of words, where the first word is the identifier.\nThere are two types of logs:\n\nLetter-logs: All words (except the identifier) consist of lowercase English letters.\nDigit-logs: All words (except the identifier) consist of digits.\n\nReorder these logs so that:\n\nThe letter-logs come before all digit-logs.\nThe letter-logs are sorted lexicographically by their contents. If their contents are the same, then sort them lexicographically by their identifiers.\nThe digit-logs maintain their relative ordering.\n\nReturn the final order of the logs.\n \nExample 1:\n\nInput: logs = [\"dig1 8 1 5 1\",\"let1 art can\",\"dig2 3 6\",\"let2 own kit dig\",\"let3 art zero\"]\nOutput: [\"let1 art can\",\"let3 art zero\",\"let2 own kit dig\",\"dig1 8 1 5 1\",\"dig2 3

6\".\n\nExample 2:\n\nInput: logs = [\"a1 9 2 3 1\",\"g1 act car\",\"zo4 4 7\",\"ab1 off key dog\",\"a8 act zoo\"]\nOutput: [\"g1 act car\",\"a8 act zoo\",\"ab1 off key dog\",\"a1 9 2 3 1\",\"zo4 4

Each coordinate point may have at most one stone.\nA stone can be removed if it shares either the same row or the same column as another stone that has not been removed.\nGiven an array stones of length n where stones[i] = [xi, yi] represents the location of the ith stone, return the largest possible number of stones that can be removed.\n \nExample 1:\n\nInput: stones = [[0,0],[0,1],[1,0],[1,2],[2,1],[2,2]]\nOutput: 5\nExplanation: One way to remove 5 stones is as follows:\n1. Remove stone [2,2] because it shares the same row as [2,1].\n2. Remove stone [2,1] because it shares the same column as [0,1].\n3. Remove stone [1,2] because it shares the same row as [1,0].\n4. Remove stone [1,0] because it shares the same column as [0,0].\n5. Remove stone [0,1] because it shares the same row as [0,0].\nStone [0,0] cannot be removed since it does not share a row/column with another stone still on the plane.\n\nExample 2:\n\nInput: stones = [[0,0],[0,2],[1,1],[2,0],[2,2]]\nOutput: 3\nExplanation: One way to make 3 moves is as follows:\n1. Remove stone [2,2] because it shares the same row as [2,0].\n2. Remove stone [2,0] because it shares the same column as [0,0].\n3. Remove stone [0,2] because it shares the same row as [0,0].\nStones [0,0] and [1,1] cannot be removed since they do not share a row/column with another stone still on the plane.\n\nExample 3:\n\nInput: stones = [[0,0]]\nOutput: 0\nExplanation: [0,0] is the only stone on the plane, so you cannot remove it.\n\n \nConstraints:\n\n1 <= stones.length <= 1000\n0 <= xi, yi <= 104\nNo two

In one move, you can play an unplayed token in one of the two ways (but not both for the same token):\n\nFace-up: If your current power is at least tokens[i], you may play tokeni, losing tokens[i] power and gaining 1 score.\nFace-down: If your current score is at least 1, you may play tokeni, gaining tokens[i] power and losing 1 score.\n\nReturn the maximum possible score you can achieve after playing any number of tokens.\n \nExample 1:\n\nInput: tokens = [100], power = 50\nOutput: 0\nExplanation: Since your score is 0 initially, you cannot play the token face-down. You also cannot play it face-up since your power (50) is less than tokens[0] (100).\n\nExample 2:\n\nInput: tokens = [200,100], power = 150\nOutput: 1\nExplanation: Play token1 (100) face-up, reducing your power to 50 and increasing your score to 1.\nThere is no need to play token0, since you cannot play it face-up to add to your score. The maximum score achievable is 1.\n\nExample 3:\n\nInput: tokens = [100,200,300,400], power = 200\nOutput: 2\nExplanation: Play the tokens in this order to get a score of 2:\n\nPlay token0 (100) face-up, reducing power to 100 and increasing score to 1.\nPlay token3 (400) face-down, increasing power to 500 and reducing score to 0.\nPlay token1 (200) face-up, reducing power to 300 and increasing score to 1.\nPlay token2 (300) face-up, reducing power to 0 and increasing score to 2.\n\nThe maximum score achievable is 2.\n\n \nConstraints:\n\n0 <= tokens.length <= 1000\n0 <=

According to lexicographical rules \"apple\" > \"app\", because 'l' > '∅', where '∅' is defined as the blank character which is less than any other character (More info).\n\n \nConstraints:\n\n1 <=

-{"question_id": 964, "task_id": "least-operators-to-express-number", "difficulty": "Hard", "problem_description": "Given a single positive integer x, we will write an expression of the form x (op1) x (op2) x (op3) x ... where each operator op1, op2, etc. is either addition, subtraction, multiplication, or division (+, -, *, or /). For example, with x = 3, we might write 3 * 3 / 3 + 3 - 3 which is a value of 3.\nWhen writing such an expression, we adhere to the following conventions:\n\nThe division operator (/) returns rational numbers.\nThere are no parentheses placed anywhere.\nWe use the usual order of operations: multiplication and division happen before addition and subtraction.\nIt is not allowed to use the unary negation operator (-). For example, \"x - x\" is a valid expression as it only uses subtraction, but \"-x + x\" is not because it uses negation.\n\nWe would like to write an expression with the least number of operators such that the expression equals the given target. Return the least number of operators used.\n \nExample 1:\n\nInput: x = 3, target = 19\nOutput: 5\nExplanation: 3 * 3 + 3 * 3 + 3 / 3.\nThe expression contains 5 operations.\n\nExample 2:\n\nInput: x = 5, target = 501\nOutput: 8\nExplanation: 5 * 5 * 5 * 5 - 5 * 5 * 5 + 5 / 5.\nThe expression contains 8 operations.\n\nExample 3:\n\nInput: x = 100, target = 100000000\nOutput: 3\nExplanation: 100 * 100 * 100 * 100.\nThe expression contains 3 operations.\n\n \nConstraints:\n\n2 <= x <= 100\n1 <= target <= 2 * 108\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n

-{"question_id": 966, "task_id": "vowel-spellchecker", "difficulty": "Medium", "problem_description": "Given a wordlist, we want to implement a spellchecker that converts a query word into a correct word.\nFor a given query word, the spell checker handles two categories of spelling mistakes:\n\nCapitalization: If the query matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the case in the wordlist.\n\n\t\nExample: wordlist = [\"yellow\"], query = \"YellOw\": correct = \"yellow\"\nExample: wordlist = [\"Yellow\"], query = \"yellow\": correct = \"Yellow\"\nExample: wordlist = [\"yellow\"], query = \"yellow\": correct = \"yellow\"\n\n\nVowel Errors: If after replacing the vowels ('a', 'e', 'i', 'o', 'u') of the query word with any vowel individually, it matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the match in the wordlist.\n\t\nExample: wordlist = [\"YellOw\"], query = \"yollow\": correct = \"YellOw\"\nExample: wordlist = [\"YellOw\"], query = \"yeellow\": correct = \"\" (no match)\nExample: wordlist = [\"YellOw\"], query = \"yllw\": correct = \"\" (no match)\n\n\n\nIn addition, the spell checker operates under the following precedence rules:\n\nWhen the query exactly matches a word in the wordlist (case-sensitive), you should return the same word back.\nWhen the query matches a word up to capitlization, you should return the first such match in the wordlist.\nWhen the query matches a word up to vowel errors, you should return the first such match in the wordlist.\nIf the query has no matches in the wordlist, you should return the empty string.\n\nGiven some queries, return a list of words answer, where answer[i] is the correct word for query = queries[i].\n \nExample 1:\nInput: wordlist = [\"KiTe\",\"kite\",\"hare\",\"Hare\"], queries = [\"kite\",\"Kite\",\"KiTe\",\"Hare\",\"HARE\",\"Hear\",\"hear\",\"keti\",\"keet\",\"keto\"]\nOutput: [\"kite\",\"KiTe\",\"KiTe\",\"Hare\",\"hare\",\"\",\"\",\"KiTe\",\"\",\"KiTe\"]\nExample 2:\nInput: wordlist = [\"yellow\"], queries = [\"YellOw\"]\nOutput: [\"yellow\"]\n\n \nConstraints:\n\n1 <= wordlist.length, queries.length <= 5000\n1 <= wordlist[i].length, queries[i].length <= 7\nwordlist[i] and queries[i] consist only of only English letters.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(wordlist = ['aeiou', 'AEIOU'],queries =

with k values 4, 2, 4, and 3.\nStarting state: arr = [3, 2, 4, 1]\nAfter 1st flip (k = 4): arr = [1, 4, 2, 3]\nAfter 2nd flip (k = 2): arr = [4, 1, 2, 3]\nAfter 3rd flip (k = 4): arr = [3, 2, 1,

anything.\nNote that other answers, such as [3, 3], would also be accepted.\n\n \nConstraints:\n\n1 <= arr.length <= 100\n1 <= arr[i] <= arr.length\nAll integers in arr are unique (i.e. arr is a

You are also given a sequence of n values voyage, which is the desired pre-order traversal of the binary tree.\nAny node in the binary tree can be flipped by swapping its left and right subtrees. For example, flipping node 1 will have the following effect:\n\nFlip the smallest number of nodes so that the pre-order traversal of the tree matches voyage.\nReturn a list of the values of all flipped nodes. You may return the answer in any order. If it is impossible to flip the nodes in the tree to make the pre-order traversal match voyage, return the list [-1].\n \nExample 1:\n\n\nInput: root = [1,2], voyage = [2,1]\nOutput: [-1]\nExplanation: It is impossible to flip the nodes such that the pre-order traversal matches voyage.\n\nExample 2:\n\n\nInput: root = [1,2,3], voyage = [1,3,2]\nOutput: [1]\nExplanation: Flipping node 1 swaps nodes 2 and 3, so the pre-order traversal matches voyage.\nExample 3:\n\n\nInput: root = [1,2,3], voyage = [1,2,3]\nOutput: []\nExplanation: The tree's pre-order traversal already matches voyage, so no nodes need to be flipped.\n\n \nConstraints:\n\nThe number of nodes in the tree is n.\nn == voyage.length\n1 <= n <= 100\n1 <= Node.val, voyage[i] <= n\nAll the values in the tree are

The answer is guaranteed to be unique (except for the order that it is in).\n \nExample 1:\n\n\nInput: points = [[1,3],[-2,2]], k = 1\nOutput: [[-2,2]]\nExplanation:\nThe distance between (1, 3) and the origin is sqrt(10).\nThe distance between (-2, 2) and the origin is sqrt(8).\nSince sqrt(8) < sqrt(10), (-2, 2) is closer to the origin.\nWe only want the closest k = 1 points from the origin, so the answer is just [[-2,2]].\n\nExample 2:\n\nInput: points = [[3,3],[5,-1],[-2,4]], k = 2\nOutput: [[3,3],[-2,4]]\nExplanation: The answer [[-2,4],[3,3]] would also be accepted.\n\n

-{"question_id": 975, "task_id": "odd-even-jump", "difficulty": "Hard", "problem_description": "You are given an integer array arr. From some starting index, you can make a series of jumps. The (1st, 3rd, 5th, ...) jumps in the series are called odd-numbered jumps, and the (2nd, 4th, 6th, ...) jumps in the series are called even-numbered jumps. Note that the jumps are numbered, not the indices.\nYou may jump forward from index i to index j (with i < j) in the following way:\n\nDuring odd-numbered jumps (i.e., jumps 1, 3, 5, ...), you jump to the index j such that arr[i] <= arr[j] and arr[j] is the smallest possible value. If there are multiple such indices j, you can only jump to the smallest such index j.\nDuring even-numbered jumps (i.e., jumps 2, 4, 6, ...), you jump to the index j such that arr[i] >= arr[j] and arr[j] is the largest possible value. If there are multiple such indices j, you can only jump to the smallest such index j.\nIt may be the case that for some index i, there are no legal jumps.\n\nA starting index is good if, starting from that index, you can reach the end of the array (index arr.length - 1) by jumping some number of times (possibly 0 or more than once).\nReturn the number of good starting indices.\n \nExample 1:\n\nInput: arr = [10,13,12,14,15]\nOutput: 2\nExplanation: \nFrom starting index i = 0, we can make our 1st jump to i = 2 (since arr[2] is the smallest among arr[1], arr[2], arr[3], arr[4] that is greater or equal to arr[0]), then we cannot jump any more.\nFrom starting index i = 1 and i = 2, we can make our 1st jump to i = 3, then we cannot jump any more.\nFrom starting index i = 3, we can make our 1st jump to i = 4, so we have reached the end.\nFrom starting index i = 4, we have reached the end already.\nIn total, there are 2 different starting indices i = 3 and i = 4, where we can reach the end with some number of\njumps.\n\nExample 2:\n\nInput: arr = [2,3,1,1,4]\nOutput: 3\nExplanation: \nFrom starting index i = 0, we make jumps to i = 1, i = 2, i = 3:\nDuring our 1st jump (odd-numbered), we first jump to i = 1 because arr[1] is the smallest value in [arr[1], arr[2], arr[3], arr[4]] that is greater than or equal to arr[0].\nDuring our 2nd jump (even-numbered), we jump from i = 1 to i = 2 because arr[2] is the largest value in [arr[2], arr[3], arr[4]] that is less than or equal to arr[1]. arr[3] is also the largest value, but 2 is a smaller index, so we can only jump to i = 2 and not i = 3\nDuring our 3rd jump (odd-numbered), we jump from i = 2 to i = 3 because arr[3] is the smallest value in [arr[3], arr[4]] that is greater than or equal to arr[2].\nWe can't jump from i = 3 to i = 4, so the starting index i = 0 is not good.\nIn a similar manner, we can deduce that:\nFrom starting index i = 1, we jump to i = 4, so we reach the end.\nFrom starting index i = 2, we jump to i = 3, and then we can't jump anymore.\nFrom starting index i = 3, we jump to i = 4, so we reach the end.\nFrom starting index i = 4, we are already at the end.\nIn total, there are 3 different starting indices i = 1, i = 3, and i = 4, where we can reach the end with some\nnumber of jumps.\n\nExample 3:\n\nInput: arr = [5,1,3,4,2]\nOutput: 3\nExplanation: We can reach the end from starting indices 1, 2, and 4.\n\n \nConstraints:\n\n1 <= arr.length <= 2 * 104\n0 <= arr[i] < 105\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

The days of the year in which you will travel are given as an integer array days. Each day is an integer from 1 to 365.\nTrain tickets are sold in three different ways:\n\na 1-day pass is sold for costs[0] dollars,\na 7-day pass is sold for costs[1] dollars, and\na 30-day pass is sold for costs[2] dollars.\n\nThe passes allow that many days of consecutive travel.\n\nFor example, if we get a 7-day pass on day 2, then we can travel for 7 days: 2, 3, 4, 5, 6, 7, and 8.\n\nReturn

one way to buy passes that lets you travel your travel plan:\nOn day 1, you bought a 1-day pass for costs[0] = $2, which covered day 1.\nOn day 3, you bought a 7-day pass for costs[1] = $7, which covered days 3, 4, ..., 9.\nOn day 20, you bought a 1-day pass for costs[0] = $2, which covered day 20.\nIn total, you spent $11 and covered all the days of your travel.\n\nExample 2:\n\nInput: days =

-{"question_id": 987, "task_id": "vertical-order-traversal-of-a-binary-tree", "difficulty": "Hard", "problem_description": "Given the root of a binary tree, calculate the vertical order traversal of the binary tree.\nFor each node at position (row, col), its left and right children will be at positions (row + 1, col - 1) and (row + 1, col + 1) respectively. The root of the tree is at (0, 0).\nThe vertical order traversal of a binary tree is a list of top-to-bottom orderings for each column index starting from the leftmost column and ending on the rightmost column. There may be multiple nodes in the same row and same column. In such a case, sort these nodes by their values.\nReturn the vertical order traversal of the binary tree.\n \nExample 1:\n\n\nInput: root = [3,9,20,null,null,15,7]\nOutput: [[9],[3,15],[20],[7]]\nExplanation:\nColumn -1: Only node 9 is in this column.\nColumn 0: Nodes 3 and 15 are in this column in that order from top to bottom.\nColumn 1: Only node 20 is in this column.\nColumn 2: Only node 7 is in this column.\nExample 2:\n\n\nInput: root = [1,2,3,4,5,6,7]\nOutput: [[4],[2],[1,5,6],[3],[7]]\nExplanation:\nColumn -2: Only node 4 is in this column.\nColumn -1: Only node 2 is in this column.\nColumn 0: Nodes 1, 5, and 6 are in this column.\n 1 is at the top, so it comes first.\n 5 and 6 are at the same position (2, 0), so we order them by their value, 5 before 6.\nColumn 1: Only node 3 is in this column.\nColumn 2: Only node 7 is in this column.\n\nExample 3:\n\n\nInput: root = [1,2,3,4,6,5,7]\nOutput: [[4],[2],[1,5,6],[3],[7]]\nExplanation:\nThis case is the exact same as example 2, but with nodes 5 and 6 swapped.\nNote that the solution remains the same since 5 and 6 are in the same location and should be ordered by their values.\n\n \nConstraints:\n\nThe number of nodes in the tree is in the range [1, 1000].\n0 <= Node.val <= 1000\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

Create a root node with the value a[i].\nThe left child of root will be Construct([a[0], a[1], ..., a[i - 1]]).\nThe right child of root will be Construct([a[i + 1], a[i + 2], ..., a[a.length - 1]]).\nReturn root.\n\nNote that we were not given a directly, only a root node root = Construct(a).\nSuppose b is a copy of a with the value val appended to it. It is guaranteed that b has unique values.\nReturn Construct(b).\n \nExample 1:\n\n\nInput: root = [4,1,3,null,null,2], val = 5\nOutput: [5,4,null,1,3,null,null,2]\nExplanation: a = [1,4,2,3], b =

-{"question_id": 1001, "task_id": "grid-illumination", "difficulty": "Hard", "problem_description": "There is a 2D grid of size n x n where each cell of this grid has a lamp that is initially turned off.\nYou are given a 2D array of lamp positions lamps, where lamps[i] = [rowi, coli] indicates that the lamp at grid[rowi][coli] is turned on. Even if the same lamp is listed more than once, it is turned on.\nWhen a lamp is turned on, it illuminates its cell and all other cells in the same row, column, or diagonal.\nYou are also given another 2D array queries, where queries[j] = [rowj, colj]. For the jth query, determine whether grid[rowj][colj] is illuminated or not. After answering the jth query, turn off the lamp at grid[rowj][colj] and its 8 adjacent lamps if they exist. A lamp is adjacent if its cell shares either a side or corner with grid[rowj][colj].\nReturn an array of integers ans, where ans[j] should be 1 if the cell in the jth query was illuminated, or 0 if the lamp was not.\n \nExample 1:\n\n\nInput: n = 5, lamps = [[0,0],[4,4]], queries = [[1,1],[1,0]]\nOutput: [1,0]\nExplanation: We have the initial grid with all lamps turned off. In the above picture we see the grid after turning on the lamp at grid[0][0] then turning on the lamp at grid[4][4].\nThe 0th query asks if the lamp at grid[1][1] is illuminated or not (the blue square). It is illuminated, so set ans[0] = 1. Then, we turn off all lamps in the red square.\n\nThe 1st query asks if the lamp at grid[1][0] is illuminated or not (the blue square). It is not illuminated, so set ans[1] = 0. Then, we turn off all lamps in the red rectangle.\n\n\nExample 2:\n\nInput: n = 5, lamps = [[0,0],[4,4]], queries = [[1,1],[1,1]]\nOutput: [1,1]\n\nExample 3:\n\nInput: n = 5, lamps = [[0,0],[0,4]],

primitive decomposition: s = P1 + P2 + ... + Pk, where Pi are primitive valid parentheses strings.\nReturn s after removing the outermost parentheses of every primitive string in the primitive decomposition of s.\n \nExample 1:\n\nInput: s = \"(()())(())\"\nOutput: \"()()()\"\nExplanation: \nThe input string is \"(()())(())\", with primitive decomposition \"(()())\" + \"(())\".\nAfter removing outer parentheses of each part, this is \"()()\" + \"()\" = \"()()()\".\n\nExample 2:\n\nInput: s = \"(()())(())(()(()))\"\nOutput: \"()()()()(())\"\nExplanation: \nThe input string is \"(()())(())(()(()))\", with primitive decomposition \"(()())\" + \"(())\" + \"(()(()))\".\nAfter removing outer parentheses of each part, this is \"()()\" + \"()\" + \"()(())\" = \"()()()()(())\".\n\nExample 3:\n\nInput: s = \"()()\"\nOutput: \"\"\nExplanation: \nThe input string is \"()()\", with primitive decomposition \"()\" + \"()\".\nAfter removing outer parentheses of each part, this is \"\" + \"\" = \"\".\n\n \nConstraints:\n\n1 <= s.length <= 105\ns[i] is either '(' or ')'.\ns is a valid parentheses string.\n\n", "canonical_tests": {"language": "python",

These video clips can be overlapping with each other and have varying lengths.\nEach video clip is described by an array clips where clips[i] = [starti, endi] indicates that the ith clip started at starti and ended at endi.\nWe can cut these clips into segments freely.\n\nFor example, a clip [0, 7] can be cut into segments [0, 1] + [1, 3] + [3, 7].\n\nReturn the minimum number of clips needed so that we can cut the clips into segments that cover the entire sporting event [0, time]. If the task is impossible, return -1.\n \nExample 1:\n\nInput: clips = [[0,2],[4,6],[8,10],[1,9],[1,5],[5,9]], time = 10\nOutput: 3\nExplanation: We take the clips [0,2], [8,10], [1,9]; a total of 3 clips.\nThen, we can reconstruct the sporting event as follows:\nWe cut [1,9] into segments [1,2] + [2,8] + [8,9].\nNow we have segments [0,2] + [2,8] + [8,10] which cover the sporting event [0, 10].\n\nExample 2:\n\nInput: clips = [[0,1],[1,2]], time = 5\nOutput: -1\nExplanation: We cannot cover [0,5] with only [0,1] and [1,2].\n\nExample 3:\n\nInput: clips =

There is a rows x cols matrix and you are on the cell with the coordinates (rCenter, cCenter).\nReturn the coordinates of all cells in the matrix, sorted by their distance from (rCenter, cCenter) from the smallest distance to the largest distance. You may return the answer in any order that satisfies this condition.\nThe distance between two cells (r1, c1) and (r2, c2) is |r1 - r2| + |c1 - c2|.\n \nExample 1:\n\nInput: rows = 1, cols = 2, rCenter = 0, cCenter = 0\nOutput: [[0,0],[0,1]]\nExplanation: The distances from (0, 0) to other cells are: [0,1]\n\nExample 2:\n\nInput: rows = 2, cols = 2, rCenter = 0, cCenter = 1\nOutput: [[0,1],[0,0],[1,1],[1,0]]\nExplanation: The distances from (0, 1) to other cells are: [0,1,1,2]\nThe answer [[0,1],[1,1],[0,0],[1,0]] would also be accepted as correct.\n\nExample 3:\n\nInput: rows =

You are given three integers a, b, and c, the positions of the stones.\nIn one move, you pick up a stone at an endpoint (i.e., either the lowest or highest position stone), and move it to an unoccupied position between those endpoints. Formally, let's say the stones are currently at positions x, y, and z with x < y < z. You pick up the stone at either position x or position z, and move that stone to an integer position k, with x < k < z and k != y.\nThe game ends when you cannot make any more moves (i.e., the stones are in three consecutive positions).\nReturn an integer array answer of length 2 where:\n\nanswer[0] is the minimum number of moves you can play, and\nanswer[1] is the maximum number of moves you can play.\n\n \nExample 1:\n\nInput: a = 1, b = 2, c = 5\nOutput: [1,2]\nExplanation: Move the stone from 5 to 3, or move the stone from 5 to 4 to 3.\n\nExample 2:\n\nInput: a = 4, b = 3, c = 2\nOutput: [0,0]\nExplanation: We cannot make any moves.\n\nExample 3:\n\nInput: a = 3, b = 5, c = 1\nOutput: [1,2]\nExplanation: Move the stone from 1 to 4; or move the stone from 1 to 2 to 4.\n\n

2\nExplanation: We can draw 2 uncrossed lines as in the diagram.\nWe cannot draw 3 uncrossed lines, because the line from nums1[1] = 4 to nums2[2] = 4 will intersect the line from nums1[2]=2 to

-{"question_id": 1039, "task_id": "minimum-score-triangulation-of-polygon", "difficulty": "Medium", "problem_description": "You have a convex n-sided polygon where each vertex has an integer value. You are given an integer array values where values[i] is the value of the ith vertex in clockwise order.\nPolygon triangulation is a process where you divide a polygon into a set of triangles and the vertices of each triangle must also be vertices of the original polygon. Note that no other shapes other than triangles are allowed in the division. This process will result in n - 2 triangles.\nYou will triangulate the polygon. For each triangle, the weight of that triangle is the product of the values at its vertices. The total score of the triangulation is the sum of these weights over all n - 2 triangles.\nReturn the minimum possible score that you can achieve with some triangulation of the polygon.\n \nExample 1:\n\n\nInput: values = [1,2,3]\nOutput: 6\nExplanation: The polygon is already triangulated, and the score of the only triangle is 6.\n\nExample 2:\n\n\nInput: values = [3,7,4,5]\nOutput: 144\nExplanation: There are two triangulations, with possible scores: 3*7*5 + 4*5*7 = 245, or 3*4*5 + 3*4*7 = 144.\nThe minimum score is 144.\n\nExample 3:\n\n\nInput: values = [1,3,1,4,1,5]\nOutput: 13\nExplanation: The minimum score triangulation is 1*1*3 + 1*1*4 + 1*1*5 + 1*1*1 = 13.\n\n \nConstraints:\n\nn == values.length\n3 <= n <= 50\n1 <= values[i] <= 100\n\n", "canonical_tests":

You are given an integer array stones, the positions of the stones.\nCall a stone an endpoint stone if it has the smallest or largest position. In one move, you pick up an endpoint stone and move it to an unoccupied position so that it is no longer an endpoint stone.\n\nIn particular, if the stones are at say, stones = [1,2,5], you cannot move the endpoint stone at position 5, since moving it to any position (such as 0, or 3) will still keep that stone as an endpoint stone.\n\nThe game ends when you cannot make any more moves (i.e., the stones are in three consecutive positions).\nReturn an integer array answer of length 2 where:\n\nanswer[0] is the minimum number of moves you can play, and\nanswer[1] is the maximum number of moves you can play.\n\n \nExample 1:\n\nInput: stones = [7,4,9]\nOutput: [1,2]\nExplanation: We can move 4 -> 8 for one move to finish the game.\nOr, we can move 9 -> 5, 4 -> 6 for two moves to finish the game.\n\nExample 2:\n\nInput: stones = [6,5,4,3,10]\nOutput: [2,3]\nExplanation: We can move 3 -> 8 then 10 -> 7 to finish the game.\nOr, we can move 3 -> 7, 4 -> 8, 5 -> 9 to finish the game.\nNotice we cannot move 10 -> 2 to finish the game, because that would be an illegal move.\n\n \nConstraints:\n\n3 <= stones.length <= 104\n1 <= stones[i] <= 109\nAll the values of stones are

On each turn, we choose any two stones and smash them together. Suppose the stones have weights x and y with x <= y. The result of this smash is:\n\nIf x == y, both stones are destroyed, and\nIf x != y, the stone of weight x is destroyed, and the stone of weight y has new weight y - x.\n\nAt the end of the game, there is at most one stone left.\nReturn the smallest possible weight of the left stone. If there are no stones left, return 0.\n \nExample 1:\n\nInput: stones = [2,7,4,1,8,1]\nOutput: 1\nExplanation:\nWe can combine 2 and 4 to get 2, so the array converts to [2,7,1,8,1] then,\nwe can combine 7 and 8 to get 1, so the array converts to [2,1,1,1] then,\nwe can combine 2 and 1 to get 1, so the array converts to [1,1,1] then,\nwe can combine 1 and 1 to get 0, so the array converts to [1], then that's the optimal value.\n\nExample 2:\n\nInput: stones = [31,26,33,21,40]\nOutput: 5\n\n \nConstraints:\n\n1 <= stones.length <= 30\n1 <= stones[i] <= 100\n\n", "canonical_tests":

baseStr.\nWe say s1[i] and s2[i] are equivalent characters.\n\nFor example, if s1 = \"abc\" and s2 = \"cde\", then we have 'a' == 'c', 'b' == 'd', and 'c' == 'e'.\n\nEquivalent characters follow the usual rules of any equivalence relation:\n\nReflexivity: 'a' == 'a'.\nSymmetry: 'a' == 'b' implies 'b' == 'a'.\nTransitivity: 'a' == 'b' and 'b' == 'c' implies 'a' == 'c'.\n\nFor example, given the equivalency information from s1 = \"abc\" and s2 = \"cde\", \"acd\" and \"aab\" are equivalent strings of baseStr = \"eed\", and \"aab\" is the lexicographically smallest equivalent string of baseStr.\nReturn the lexicographically smallest equivalent string of baseStr by using the equivalency information from s1 and s2.\n \nExample 1:\n\nInput: s1 = \"parker\", s2 = \"morris\", baseStr = \"parser\"\nOutput: \"makkek\"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [m,p], [a,o], [k,r,s], [e,i].\nThe characters in each group are equivalent and sorted in lexicographical order.\nSo the answer is \"makkek\".\n\nExample 2:\n\nInput: s1 = \"hello\", s2 = \"world\", baseStr = \"hold\"\nOutput: \"hdld\"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [h,w], [d,e,o], [l,r].\nSo only the second letter 'o' in baseStr is changed to 'd', the answer is \"hdld\".\n\nExample 3:\n\nInput: s1 = \"leetcode\", s2 = \"programs\", baseStr = \"sourcecode\"\nOutput: \"aauaaaaada\"\nExplanation: We group the equivalent characters in s1 and s2 as [a,o,e,r,s,c], [l,p], [g,t] and [d,m], thus all letters in baseStr except 'u' and 'd' are transformed to 'a', the answer is \"aauaaaaada\".\n\n \nConstraints:\n\n1 <= s1.length, s2.length, baseStr <= 1000\ns1.length ==

-{"question_id": 1096, "task_id": "brace-expansion-ii", "difficulty": "Hard", "problem_description": "Under the grammar given below, strings can represent a set of lowercase words. Let R(expr) denote the set of words the expression represents.\nThe grammar can best be understood through simple examples:\n\nSingle letters represent a singleton set containing that word.\n\t\nR(\"a\") = {\"a\"}\nR(\"w\") = {\"w\"}\n\n\nWhen we take a comma-delimited list of two or more expressions, we take the union of possibilities.\n\t\nR(\"{a,b,c}\") = {\"a\",\"b\",\"c\"}\nR(\"{{a,b},{b,c}}\") = {\"a\",\"b\",\"c\"} (notice the final set only contains each word at most once)\n\n\nWhen we concatenate two expressions, we take the set of possible concatenations between two words where the first word comes from the first expression and the second word comes from the second expression.\n\t\nR(\"{a,b}{c,d}\") = {\"ac\",\"ad\",\"bc\",\"bd\"}\nR(\"a{b,c}{d,e}f{g,h}\") = {\"abdfg\", \"abdfh\", \"abefg\", \"abefh\", \"acdfg\", \"acdfh\", \"acefg\", \"acefh\"}\n\n\n\nFormally, the three rules for our grammar:\n\nFor every lowercase letter x, we have R(x) = {x}.\nFor expressions e1, e2, ... , ek with k >= 2, we have R({e1, e2, ...}) = R(e1) ∪ R(e2) ∪ ...\nFor expressions e1 and e2, we have R(e1 + e2) = {a + b for (a, b) in R(e1) × R(e2)}, where + denotes concatenation, and × denotes the cartesian product.\n\nGiven an expression representing a set of words under the given grammar, return the sorted list of words that the expression represents.\n \nExample 1:\n\nInput: expression = \"{a,b}{c,{d,e}}\"\nOutput: [\"ac\",\"ad\",\"ae\",\"bc\",\"bd\",\"be\"]\n\nExample 2:\n\nInput: expression = \"{{a,z},a{b,c},{ab,z}}\"\nOutput: [\"a\",\"ab\",\"ac\",\"z\"]\nExplanation: Each distinct word is written only once in the final answer.\n\n \nConstraints:\n\n1 <= expression.length <= 60\nexpression[i] consists of '{', '}', ','or lowercase English letters.\nThe given expression represents a set of words based on the grammar given in the description.\n\n", "canonical_tests":

-{"question_id": 1103, "task_id": "distribute-candies-to-people", "difficulty": "Easy", "problem_description": "We distribute some number of candies, to a row of n = num_people people in the following way:\nWe then give 1 candy to the first person, 2 candies to the second person, and so on until we give n candies to the last person.\nThen, we go back to the start of the row, giving n + 1 candies to the first person, n + 2 candies to the second person, and so on until we give 2 * n candies to the last person.\nThis process repeats (with us giving one more candy each time, and moving to the start of the row after we reach the end) until we run out of candies. The last person will receive all of our remaining candies (not necessarily one more than the previous gift).\nReturn an array (of length num_people and sum candies) that represents the final distribution of candies.\n \nExample 1:\n\nInput: candies = 7, num_people = 4\nOutput: [1,2,3,1]\nExplanation:\nOn the first turn, ans[0] += 1, and the array is [1,0,0,0].\nOn the second turn, ans[1] += 2, and the array is [1,2,0,0].\nOn the third turn, ans[2] += 3, and the array is [1,2,3,0].\nOn the fourth turn, ans[3] += 1 (because there is only one candy left), and the final array is [1,2,3,1].\n\nExample 2:\n\nInput: candies = 10, num_people = 3\nOutput: [5,2,3]\nExplanation: \nOn the first turn, ans[0] += 1, and the array is [1,0,0].\nOn the second turn, ans[1] += 2, and the array is [1,2,0].\nOn the third turn, ans[2] += 3, and the array is [1,2,3].\nOn the fourth turn, ans[0] += 4, and the final array is [5,2,3].\n\n \nConstraints:\n\n1 <= candies <= 10^9\n1 <=

You are also given an integer shelfWidth.\nWe want to place these books in order onto bookcase shelves that have a total width shelfWidth.\nWe choose some of the books to place on this shelf such that the sum of their thickness is less than or equal to shelfWidth, then build another level of the shelf of the bookcase so that the total height of the bookcase has increased by the maximum height of the books we just put down. We repeat this process until there are no more books to place.\nNote that at each step of the above process, the order of the books we place is the same order as the given sequence of books.\n\nFor example, if we have an ordered list of 5 books, we might place the first and second book onto the first shelf, the third book on the second shelf, and the fourth and fifth book on the last shelf.\n\nReturn the minimum possible height that the total bookshelf can be after placing shelves in this manner.\n \nExample 1:\n\n\nInput: books = [[1,1],[2,3],[2,3],[1,1],[1,1],[1,1],[1,2]], shelfWidth = 4\nOutput: 6\nExplanation:\nThe sum of the heights of the 3 shelves is 1 + 3 + 2 = 6.\nNotice that book number 2 does not have to be on the first shelf.\n\nExample 2:\n\nInput: books = [[1,3],[2,4],[3,2]], shelfWidth = 6\nOutput: 4\n\n \nConstraints:\n\n1 <= books.length <= 1000\n1 <= thicknessi <= shelfWidth <= 1000\n1 <= heighti <= 1000\n\n", "canonical_tests": {"language":

-{"question_id": 1123, "task_id": "lowest-common-ancestor-of-deepest-leaves", "difficulty": "Medium", "problem_description": "Given the root of a binary tree, return the lowest common ancestor of its deepest leaves.\nRecall that:\n\nThe node of a binary tree is a leaf if and only if it has no children\nThe depth of the root of the tree is 0. if the depth of a node is d, the depth of each of its children is d + 1.\nThe lowest common ancestor of a set S of nodes, is the node A with the largest depth such that every node in S is in the subtree with root A.\n\n \nExample 1:\n\n\nInput: root = [3,5,1,6,2,0,8,null,null,7,4]\nOutput: [2,7,4]\nExplanation: We return the node with value 2, colored in yellow in the diagram.\nThe nodes coloured in blue are the deepest leaf-nodes of the tree.\nNote that nodes 6, 0, and 8 are also leaf nodes, but the depth of them is 2, but the depth of nodes 7 and 4 is 3.\nExample 2:\n\nInput: root = [1]\nOutput: [1]\nExplanation: The root is the deepest node in the tree, and it's the lca of itself.\n\nExample 3:\n\nInput: root = [0,1,3,null,2]\nOutput: [2]\nExplanation: The deepest leaf node in the tree is 2, the lca of one node is itself.\n\n \nConstraints:\n\nThe number of nodes in the tree will be in the range [1, 1000].\n0 <= Node.val <= 1000\nThe values of the nodes in the tree are unique.\n\n \nNote: This question is the

-{"question_id": 1140, "task_id": "stone-game-ii", "difficulty": "Medium", "problem_description": "Alice and Bob continue their games with piles of stones. There are a number of piles arranged in a row, and each pile has a positive integer number of stones piles[i]. The objective of the game is to end with the most stones.\nAlice and Bob take turns, with Alice starting first.\nOn each player's turn, that player can take all the stones in the first X remaining piles, where 1 <= X <= 2M. Then, we set M = max(M, X). Initially, M = 1.\nThe game continues until all the stones have been taken.\nAssuming Alice and Bob play optimally, return the maximum number of stones Alice can get.\n \nExample 1:\n\nInput: piles = [2,7,9,4,4]\nOutput: 10\nExplanation:\n\nIf Alice takes one pile at the beginning, Bob takes two piles, then Alice takes 2 piles again. Alice can get 2 + 4 + 4 = 10 stones in total.\nIf Alice takes two piles at the beginning, then Bob can take all three piles left. In this case, Alice get 2 + 7 = 9 stones in total.\n\nSo we return 10 since it's larger.\n\nExample 2:\n\nInput: piles = [1,2,3,4,5,100]\nOutput: 104\n\n \nConstraints:\n\n1 <= piles.length <= 100\n1

In each turn, that player chooses a node of their color (red if player 1, blue if player 2) and colors an uncolored neighbor of the chosen node (either the left child, right child, or parent of the chosen node.)\nIf (and only if) a player cannot choose such a node in this way, they must pass their turn. If both players pass their turn, the game ends, and the winner is the player that colored more nodes.\nYou are the second player. If it is possible to choose such a y to ensure you win the game, return true. If it is not possible, return false.\n \nExample 1:\n\n\nInput: root = [1,2,3,4,5,6,7,8,9,10,11], n = 11, x = 3\nOutput: true\nExplanation: The second player can choose the node with value 2.\n\nExample 2:\n\nInput: root = [1,2,3], n = 3, x = 1\nOutput: false\n\n \nConstraints:\n\nThe number of nodes in the tree is n.\n1 <= x <= n <= 100\nn is odd.\n1 <= Node.val <= n\nAll the values of the tree are unique.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25]),n = 25,x = 13) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5]),n = 5,x = 2) == False\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6]),n = 6,x = 4) == True\n assert candidate(root = tree_node([1, 2, 3, None, 4, 5, 6]),n = 7,x = 5) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]),n = 11,x = 3) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7]),n = 7,x = 5) == True\n assert candidate(root = tree_node([1, 2, 3]),n = 3,x = 1) == False\n assert candidate(root = tree_node([1, None, 2, None, 3, None, 4, None, 5, None, 6, None, 7, None, 8, None, 9, None, 10]),n = 10,x = 5) == False\n assert candidate(root = tree_node([1, None, 2, None, 3, None, 4, None, 5]),n = 5,x = 1) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31]),n = 31,x = 16) == True\n assert candidate(root = tree_node([4, 2, 7, 1, 3, 6, 9]),n = 7,x = 4) == False\n assert candidate(root = tree_node([6, 3, 8, 2, 4, 7, 9, 1, 5, None, None, None, None, None, None]),n = 9,x = 6) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9]),n = 9,x = 4) == True\n assert candidate(root = tree_node([3, 1, 5, 0, 2, 4, 6]),n = 7,x = 3) == False\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7]),n = 7,x = 4) == True\n assert candidate(root = tree_node([5, 3, 6, 2, 4, None, None, 1]),n = 7,x = 3) == False\n assert candidate(root = tree_node([1, None, 2, None, 3, None, 4, None, 5, None, 6, None, 7, None, 8, None, 9, None, 10, None, 11, None, 12, None, 13, None, 14, None, 15]),n = 15,x = 7) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7]),n = 7,x = 2) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]),n = 15,x = 8) == True\n assert candidate(root = tree_node([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]),n = 15,x = 7) == True\n"}, "metadata": {"canonical_parameter_names": ["root", "n", "x"], "leetcode_dataset_entry_point": "Solution().btreeGameWinningMove", "problem_source": "newfacade/LeetCodeDataset", "interface_source": "leetcode/codeSnippets"}, "language": "python", "interface": {"raw_signature": "def btreeGameWinningMove(self, root: TreeNode | None, n: int, x: int) -> bool:", "container": "Solution", "callable": "btreeGameWinningMove", "parameters": [{"name": "root", "type": "TreeNode | None"}, {"name": "n", "type": "int"}, {"name": "x", "type": "int"}], "return_type": "bool", "signature_source": "leetcode/codeSnippets", "type_source": "leetcode/codeSnippets"}}

You may return the answer in any order.\n \nExample 1:\n\nInput: transactions = [\"alice,20,800,mtv\",\"alice,50,100,beijing\"]\nOutput: [\"alice,20,800,mtv\",\"alice,50,100,beijing\"]\nExplanation: The first transaction is invalid because the second transaction occurs within a difference of 60 minutes, have the same name and is in a different city. Similarly the second one is invalid too.\nExample 2:\n\nInput: transactions = [\"alice,20,800,mtv\",\"alice,50,1200,mtv\"]\nOutput: [\"alice,50,1200,mtv\"]\n\nExample 3:\n\nInput: transactions = [\"alice,20,800,mtv\",\"bob,50,1200,mtv\"]\nOutput: [\"bob,50,1200,mtv\"]\n\n \nConstraints:\n\ntransactions.length <= 1000\nEach transactions[i] takes the form \"{name},{time},{amount},{city}\"\nEach {name} and {city} consist of lowercase English letters, and have lengths between 1 and 10.\nEach {time} consist of digits, and represent an integer between 0 and 1000.\nEach {amount} consist of digits, and represent an integer between 0 and 2000.\n\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(transactions = ['alice,20,800,mtv',

The grid has empty cells represented by zeros and blocked cells represented by ones. The snake wants to reach the lower right corner at (n-1, n-2) and (n-1, n-1).\nIn one move the snake can:\n\nMove one cell to the right if there are no blocked cells there. This move keeps the horizontal/vertical position of the snake as it is.\nMove down one cell if there are no blocked cells there. This move keeps the horizontal/vertical position of the snake as it is.\nRotate clockwise if it's in a horizontal position and the two cells under it are both empty. In that case the snake moves from (r, c) and (r, c+1) to (r, c) and (r+1, c).\n\nRotate counterclockwise if it's in a vertical position and the two cells to its right are both empty. In that case the snake moves from (r, c) and (r+1, c) to (r, c) and (r, c+1).\n\n\nReturn the minimum number of moves to reach the target.\nIf there is no way to reach the target, return -1.\n \nExample 1:\n\n\nInput: grid = [[0,0,0,0,0,1],\n [1,1,0,0,1,0],\n [0,0,0,0,1,1],\n [0,0,1,0,1,0],\n [0,1,1,0,0,0],\n [0,1,1,0,0,0]]\nOutput: 11\nExplanation:\nOne possible solution is [right, right, rotate clockwise, right, down, down, down, down, rotate counterclockwise, right, down].\n\nExample 2:\n\nInput: grid = [[0,0,1,1,1,1],\n [0,0,0,0,1,1],\n [1,1,0,0,0,1],\n [1,1,1,0,0,1],\n [1,1,1,0,0,1],\n [1,1,1,0,0,0]]\nOutput: 9\n\n \nConstraints:\n\n2 <= n <= 100\n0 <= grid[i][j] <= 1\nIt is guaranteed that the snake starts at empty cells.\n\n", "canonical_tests": {"language":

The player can move up, down, left, right in grid if it is a floor (empty cell).\nThe character '.' represents the floor which means a free cell to walk.\nThe character '#' represents the wall which means an obstacle (impossible to walk there).\nThere is only one box 'B' and one target cell 'T' in the grid.\nThe box can be moved to an adjacent free cell by standing next to the box and then moving in the direction of the box.

-{"question_id": 1268, "task_id": "search-suggestions-system", "difficulty": "Medium", "problem_description": "You are given an array of strings products and a string searchWord.\nDesign a system that suggests at most three product names from products after each character of searchWord is typed. Suggested products should have common prefix with searchWord. If there are more than three products with a common prefix return the three lexicographically minimums products.\nReturn a list of lists of the suggested products after each character of searchWord is typed.\n \nExample 1:\n\nInput: products = [\"mobile\",\"mouse\",\"moneypot\",\"monitor\",\"mousepad\"], searchWord = \"mouse\"\nOutput: [[\"mobile\",\"moneypot\",\"monitor\"],[\"mobile\",\"moneypot\",\"monitor\"],[\"mouse\",\"mousepad\"],[\"mouse\",\"mousepad\"],[\"mouse\",\"mousepad\"]]\nExplanation: products sorted lexicographically = [\"mobile\",\"moneypot\",\"monitor\",\"mouse\",\"mousepad\"].\nAfter typing m and mo all products match and we show user [\"mobile\",\"moneypot\",\"monitor\"].\nAfter typing mou, mous and mouse the system suggests [\"mouse\",\"mousepad\"].\n\nExample 2:\n\nInput: products = [\"havana\"], searchWord = \"havana\"\nOutput: [[\"havana\"],[\"havana\"],[\"havana\"],[\"havana\"],[\"havana\"],[\"havana\"]]\nExplanation: The only word \"havana\" will be always suggested while typing the search word.\n\n \nConstraints:\n\n1 <=

You are given four arrays: status, candies, keys, and containedBoxes where:\n\nstatus[i] is 1 if the ith box is open and 0 if the ith box is closed,\ncandies[i] is the number of candies in the ith box,\nkeys[i] is a list of the labels of the boxes you can open after opening the ith box.\ncontainedBoxes[i] is a list of the boxes you found inside the ith box.\n\nYou are given an integer array initialBoxes that contains the labels of the boxes you initially have. You can take all the candies in any open box and you can use the keys in it to open new boxes and you also can use the boxes you find in it.\nReturn the maximum number of candies you can get following the rules above.\n \nExample 1:\n\nInput: status = [1,0,1,0], candies = [7,5,4,100], keys = [[],[],[1],[]], containedBoxes = [[1,2],[3],[],[]], initialBoxes = [0]\nOutput: 16\nExplanation: You will be initially given box 0. You will find 7 candies in it and boxes 1 and 2.\nBox 1 is closed and you do not have a key for it so you will open box 2. You will find 4 candies and a key to box 1 in box 2.\nIn box 1, you will find 5 candies and box 3 but you will not find a key to box 3 so box 3 will remain closed.\nTotal number of candies collected = 7 + 4 + 5 = 16 candy.\n\nExample 2:\n\nInput: status = [1,0,0,0,0,0], candies = [1,1,1,1,1,1], keys = [[1,2,3,4,5],[],[],[],[],[]], containedBoxes = [[1,2,3,4,5],[],[],[],[],[]], initialBoxes = [0]\nOutput: 6\nExplanation: You have initially box 0. Opening it you can find boxes 1,2,3,4 and 5 and their keys.\nThe total number of candies will be 6.\n\n \nConstraints:\n\nn == status.length == candies.length == keys.length ==

If there is no such route, return -1.\n\nExample 1:\n\nInput: n = 4, flights = [[0,1,100],[1,2,100],[2,0,100],[1,3,600],[2,3,200]], src = 0, dst = 3, k = 1\nOutput: 700\nExplanation:\nThe graph is shown above.\nThe optimal path with at most 1 stop from city 0 to 3 is marked in red and has cost 100 + 600 = 700.\nNote that the path through cities [0,1,2,3] is cheaper but is invalid because it

+{"question_id": 789, "task_id": "escape-the-ghosts", "difficulty": "Medium", "problem_description": "You are playing a simplified PAC-MAN game on an infinite 2-D grid. You start at the point [0, 0], and you are given a destination point target = [x_target, y_target] that you are trying to get to. There are several ghosts on the map with their starting positions given as a 2D array ghosts, where ghosts[i] = [x_i, y_i] represents the starting position of the i^th ghost. All inputs are integral coordinates.\n\nEach turn, you and all the ghosts may independently choose to either move 1 unit in any of the four cardinal directions: north, east, south, or west, or stay still. All actions happen simultaneously.\n\nYou escape if and only if you can reach the target before any ghost reaches you. If you reach any square (including the target) at the same time as a ghost, it does not count as an escape.\n\nReturn true if it is possible to escape regardless of how the ghosts move, otherwise return false.\n\nExample 1:\n\nInput: ghosts = [[1,0],[0,3]], target = [0,1]\nOutput: true\nExplanation: You can reach the destination (0, 1) after 1 turn, while the ghosts located at (1, 0) and (0, 3) cannot catch up with you.\n\nExample 2:\n\nInput: ghosts = [[1,0]], target = [2,0]\nOutput: false\nExplanation: You need to reach the destination (2, 0), but the ghost at (1, 0) lies between you and the destination.\n\nExample 3:\n\nInput: ghosts = [[2,0]], target = [1,0]\nOutput: false\nExplanation: The ghost can reach the target at the same time as you.\n\nConstraints:\n\n- 1 <=

+{"question_id": 798, "task_id": "smallest-rotation-with-highest-score", "difficulty": "Hard", "problem_description": "You are given an array nums. You can rotate it by a non-negative integer k so that the array becomes [nums[k], nums[k + 1], ... nums[nums.length - 1], nums[0], nums[1], ..., nums[k-1]]. Afterward, any entries that are less than or equal to their index are worth one point.\n\n- For example, if we have nums = [2,4,1,3,0], and we rotate by k = 2, it becomes [1,3,0,2,4]. This is worth 3 points because 1 > 0 [no points], 3 > 1 [no points], 0 <= 2 [one point], 2 <= 3 [one point], 4 <= 4 [one point].\n\nReturn the rotation index k that corresponds to the highest score we can achieve if we rotated nums by it. If there are multiple answers, return the smallest such index k.\n\nExample 1:\n\nInput: nums = [2,3,1,4,0]\nOutput: 3\nExplanation: Scores for each k are listed below:\nk = 0, nums = [2,3,1,4,0], score 2\nk = 1, nums = [3,1,4,0,2], score 3\nk = 2, nums = [1,4,0,2,3], score 3\nk = 3, nums = [4,0,2,3,1], score 4\nk = 4, nums = [0,2,3,1,4], score 3\nSo we should choose k = 3, which has the highest score.\n\nExample 2:\n\nInput: nums = [1,3,0,2,4]\nOutput: 0\nExplanation: nums will always have 3 points no matter how it shifts.\nSo we will choose the smallest k, which is 0.\n\nConstraints:\n\n- 1 <= nums.length <= 10^5\n- 0 <= nums[i] < nums.length\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(nums = [1, 3, 0, 2, 4])

When the topmost glass is full, any excess liquid poured will fall equally to the glass immediately to the left and right of it.

In one operation, you are allowed to swap nums1[i] with nums2[i].\n\n- For example, if nums1 = [1,2,3,8], and nums2 = [5,6,7,4], you can swap the element at i = 3 to obtain nums1 = [1,2,3,4] and nums2 = [5,6,7,8].\n\nReturn the minimum number of needed operations to make nums1 and nums2 strictly increasing. The test cases are generated so that the given input always makes it possible.\n\nAn array arr is strictly increasing if and only if arr[0] < arr[1] < arr[2] < ... < arr[arr.length - 1].\n\nExample 1:\n\nInput: nums1 = [1,3,5,4], nums2 = [1,2,3,7]\nOutput: 1\nExplanation:\nSwap nums1[3] and nums2[3].

A node is a safe node if every possible path starting from that node leads to a terminal node (or another safe node).\n\nReturn an array containing all the safe nodes of the graph. The answer should be sorted in ascending order.\n\nExample 1:\n\nInput: graph = [[1,2],[2,3],[5],[0],[5],[],[]]\nOutput: [2,4,5,6]\nExplanation: The given graph is shown above.\nNodes 5 and 6 are terminal nodes as there are no outgoing edges from either of them.\nEvery path starting at nodes 2, 4, 5, and 6 all lead to either node 5 or 6.\n\nExample 2:\n\nInput: graph =

+{"question_id": 803, "task_id": "bricks-falling-when-hit", "difficulty": "Hard", "problem_description": "You are given an m x n binary grid, where each 1 represents a brick and 0 represents an empty space. A brick is stable if:\n\n- It is directly connected to the top of the grid, or\n- At least one other brick in its four adjacent cells is stable.\n\nYou are also given an array hits, which is a sequence of erasures we want to apply. Each time we want to erase the brick at the location hits[i] = (row_i, col_i). The brick on that location (if it exists) will disappear. Some other bricks may no longer be stable because of that erasure and will fall. Once a brick falls, it is immediately erased from the grid (i.e., it does not land on other stable bricks).\n\nReturn an array result, where each result[i] is the number of bricks that will fall after the i^th erasure is applied.\n\nNote that an erasure may refer to a location with no brick, and if it does, no bricks drop.\n\nExample 1:\n\nInput: grid = [[1,0,0,0],[1,1,1,0]], hits = [[1,0]]\nOutput: [2]\nExplanation: Starting with the grid:\n[[1,0,0,0],\n [1,1,1,0]]\nWe erase the underlined brick at (1,0), resulting in the grid:\n[[1,0,0,0],\n [0,1,1,0]]\nThe two underlined bricks are no longer stable as they are no longer connected to the top nor adjacent to another stable brick, so they will fall. The resulting grid is:\n[[1,0,0,0],\n [0,0,0,0]]\nHence the result is [2].\n\nExample 2:\n\nInput: grid = [[1,0,0,0],[1,1,0,0]], hits = [[1,1],[1,0]]\nOutput: [0,0]\nExplanation: Starting with the grid:\n[[1,0,0,0],\n [1,1,0,0]]\nWe erase the underlined brick at (1,1), resulting in the grid:\n[[1,0,0,0],\n [1,0,0,0]]\nAll remaining bricks are still stable, so no bricks fall. The grid remains the same:\n[[1,0,0,0],\n [1,0,0,0]]\nNext, we erase the underlined brick at (1,0), resulting in the grid:\n[[1,0,0,0],\n [0,0,0,0]]\nOnce again, all remaining bricks are still stable, so no bricks fall.\nHence the result is [0,0].\n\nConstraints:\n\n- m == grid.length\n- n == grid[i].length\n- 1 <= m, n <= 200\n- grid[i][j] is 0 or 1.\n- 1 <= hits.length <= 4 * 10^4\n-

+{"question_id": 808, "task_id": "soup-servings", "difficulty": "Medium", "problem_description": "You have two soups, A and B, each starting with n mL. On every turn, one of the following four serving operations is chosen at random, each with probability 0.25 independent of all previous turns:\n\n- pour 100 mL from type A and 0 mL from type B\n- pour 75 mL from type A and 25 mL from type B\n- pour 50 mL from type A and 50 mL from type B\n- pour 25 mL from type A and 75 mL from type B\n\nNote:\n\n- There is no operation that pours 0 mL from A and 100 mL from B.\n- The amounts from A and B are poured simultaneously during the turn.\n- If an operation asks you to pour more than you have left of a soup, pour all that remains of that soup.\n\nThe process stops immediately after any turn in which one of the soups is used up.\n\nReturn the probability that A is used up before B, plus half the probability that both soups are used up in the same turn. Answers within 10^-5 of the actual answer will be accepted.\n\nExample 1:\n\nInput: n = 50\nOutput: 0.62500\nExplanation:\nIf we perform either of the first two serving operations, soup A will become empty first.\nIf we perform the third operation, A and B will become empty at the same time.\nIf we perform the fourth operation, B will become empty first.\nSo the total probability of A becoming empty first plus half the probability that A and B become empty at the same time, is 0.25 * (1 + 1 + 0.5 + 0) = 0.625.\n\nExample 2:\n\nInput: n = 100\nOutput: 0.71875\nExplanation:\nIf we perform the first serving operation, soup A will become empty first.\nIf we perform the second serving operations, A will become empty on performing operation [1, 2, 3], and both A and B become empty on performing operation 4.\nIf we perform the third operation, A will become empty on performing operation [1, 2], and both A and B become empty on performing operation 3.\nIf we perform the fourth operation, A will become empty on performing operation 1, and both A and B become empty on performing operation 2.\nSo the total probability of A becoming empty first plus half the probability that A and B become empty at the same time, is 0.71875.\n\nConstraints:\n\n- 0 <= n <= 10^9\n", "canonical_tests": {"language": "python", "source": "def answers_match(result, expected):\n \"\"\"Decimal

For example:\n\n- \"hello\" -> \"heeellooo\"\n- \"hi\" -> \"hiiii\"\n\nIn these strings like \"heeellooo\", we have groups of adjacent letters that are all the same: \"h\", \"eee\", \"ll\", \"ooo\".\n\nYou are given a string s and an array of query strings words. A query word is stretchy if it can be made to be equal to s by any number of applications of the following extension operation: choose a group consisting of characters c, and add some number of characters c to the group so that the size of the group is three or more.\n\n- For example, starting with \"hello\", we could do an extension on the group \"o\" to get \"hellooo\", but we cannot get \"helloo\" since the group \"oo\" has a size less than three. Also, we could do another extension like \"ll\" -> \"lllll\" to get \"helllllooo\". If s = \"helllllooo\", then the query word \"hello\" would be stretchy because of these two extension operations: query = \"hello\" -> \"hellooo\" -> \"helllllooo\" = s.\n\nReturn the number of query

+{"question_id": 811, "task_id": "subdomain-visit-count", "difficulty": "Medium", "problem_description": "A website domain \"discuss.leetcode.com\" consists of various subdomains. At the top level, we have \"com\", at the next level, we have \"leetcode.com\" and at the lowest level, \"discuss.leetcode.com\". When we visit a domain like \"discuss.leetcode.com\", we will also visit the parent domains \"leetcode.com\" and \"com\" implicitly.\n\nA count-paired domain is a domain that has one of the two formats \"rep d1.d2.d3\" or \"rep d1.d2\" where rep is the number of visits to the domain and d1.d2.d3 is the domain itself.\n\n- For example, \"9001 discuss.leetcode.com\" is a count-paired domain that indicates that discuss.leetcode.com was visited 9001 times.\n\nGiven an array of count-paired domains cpdomains, return an array of the count-paired domains of each subdomain in the input. You may return the answer in any order.\n\nExample 1:\n\nInput: cpdomains = [\"9001 discuss.leetcode.com\"]\nOutput: [\"9001 leetcode.com\",\"9001 discuss.leetcode.com\",\"9001 com\"]\nExplanation: We only have one website domain: \"discuss.leetcode.com\".\nAs discussed above, the subdomain \"leetcode.com\" and \"com\" will also be visited. So they will all be visited 9001 times.\n\nExample 2:\n\nInput: cpdomains = [\"900 google.mail.com\", \"50 yahoo.com\", \"1 intel.mail.com\", \"5 wiki.org\"]\nOutput: [\"901 mail.com\",\"50 yahoo.com\",\"900 google.mail.com\",\"5 wiki.org\",\"5 org\",\"1 intel.mail.com\",\"951 com\"]\nExplanation: We will visit \"google.mail.com\" 900 times, \"yahoo.com\" 50 times, \"intel.mail.com\" once and \"wiki.org\" 5 times.\nFor the subdomains, we will visit \"mail.com\" 900 + 1 = 901 times, \"com\" 900 + 50 + 1 = 951 times, and \"org\" 5 times.\n\nConstraints:\n\n- 1 <= cpdomain.length <= 100\n- 1 <= cpdomain[i].length <= 100\n- cpdomain[i] follows either the \"rep_i d1_i.d2_i.d3_i\" format or the \"rep_i d1_i.d2_i\" format.\n- rep_i is an integer in the range [1, 10^4].\n- d1_i, d2_i,

You can partition the array into at most k non-empty adjacent subarrays. The score of a partition is the sum of the averages of each subarray.\n\nNote that the partition must use every integer in nums, and that the score is not necessarily an integer.\n\nReturn the maximum score you can achieve of all the possible partitions. Answers within 10^-6 of the actual answer will be accepted.\n\nExample 1:\n\nInput: nums = [9,1,2,3,9], k = 3\nOutput: 20.00000\nExplanation:\nThe best choice is to partition nums into [9], [1, 2, 3], [9]. The answer is 9 + (1 + 2 + 3) / 3 + 9 = 20.\nWe could have also partitioned nums into [9, 1], [2], [3, 9], for example.\nThat partition would lead to a score of 5 + 2 + 6 = 13, which is worse.\n\nExample 2:\n\nInput: nums = [1,2,3,4,5,6,7], k = 4\nOutput: 20.50000\n\nConstraints:\n\n- 1 <= nums.length <= 100\n- 1 <= nums[i] <= 10^4\n- 1 <= k <= nums.length\n", "canonical_tests":

Initially, each card is placed on a table such that the front number is facing up and the other is facing down. You may flip over any number of cards (possibly zero).\n\nAfter flipping the cards, an integer is considered good if it is facing down on some card and not facing up on any card.\n\nReturn the minimum possible good integer after flipping the cards. If there are no good integers, return 0.\n\nExample 1:\n\nInput: fronts = [1,2,4,4,7], backs = [1,3,4,1,3]\nOutput: 2\nExplanation:\nIf we flip the second card, the face up numbers are [1,3,4,4,7] and the face down are [1,2,4,1,3].\n2 is the minimum good integer as it appears facing down but not facing up.\nIt can be shown that 2 is the minimum possible good integer obtainable after flipping some cards.\n\nExample 2:\n\nInput: fronts = [1], backs = [1]\nOutput: 0\nExplanation:\nThere are no good integers no matter how we flip the cards, so we return 0.\n\nConstraints:\n\n- n == fronts.length

+{"question_id": 824, "task_id": "goat-latin", "difficulty": "Easy", "problem_description": "You are given a string sentence that consist of words separated by spaces. Each word consists of lowercase and uppercase letters only.\n\nWe would like to convert the sentence to \"Goat Latin\" (a made-up language similar to Pig Latin.) The rules of Goat Latin are as follows:\n\n- If a word begins with a vowel ('a', 'e', 'i', 'o', or 'u'), append \"ma\" to the end of the word.\n - For example, the word \"apple\" becomes \"applema\".\n- If a word begins with a consonant (i.e., not a vowel), remove the first letter and append it to the end, then add \"ma\".\n - For example, the word \"goat\" becomes \"oatgma\".\n- Add one letter 'a' to the end of each word per its word index in the sentence, starting with 1.\n - For example, the first word gets \"a\" added to the end, the second word gets \"aa\" added to the end, and so on.\n\nReturn the final sentence representing the conversion from sentence to Goat Latin.\n\nExample 1:\n\nInput: sentence = \"I speak Goat Latin\"\nOutput: \"Imaa peaksmaaa oatGmaaaa

You are given three arrays: difficulty, profit, and worker where:\n\n- difficulty[i] and profit[i] are the difficulty and the profit of the i^th job, and\n- worker[j] is the ability of j^th worker (i.e., the j^th worker can only complete a job with difficulty at most worker[j]).\n\nEvery worker can be assigned at most one job, but one job can be completed multiple times.\n\n- For example, if three workers attempt the same job that pays $1, then the total profit will be $3. If a worker cannot complete any job, their profit is $0.\n\nReturn the maximum profit we can achieve after assigning the workers to the jobs.\n\nExample 1:\n\nInput: difficulty = [2,4,6,8,10], profit

The test cases are generated such that the answer fits in a 32-bit integer.\n\nNotice that some substrings can be repeated so in this case you have to count the repeated ones too.\n\nExample 1:\n\nInput: s = \"ABC\"\nOutput: 10\nExplanation: All possible substrings are: \"A\",\"B\",\"C\",\"AB\",\"BC\" and \"ABC\".\nEvery substring is composed with only unique letters.\nSum of lengths of

+{"question_id": 831, "task_id": "masking-personal-information", "difficulty": "Medium", "problem_description": "You are given a personal information string s, representing either an email address or a phone number. Return the masked personal information using the below rules.\n\nEmail address:\n\nAn email address is:\n\n- A name consisting of at least two uppercase and lowercase English letters, followed by\n- The '@' symbol, followed by\n- The domain consisting of uppercase and lowercase English letters with a dot '.' somewhere in the middle (not the first or last character).\n\nTo mask an email:\n\n- The uppercase letters in the name and domain must be converted to lowercase letters.\n- The middle letters of the name (i.e., all but the first and last letters) must be replaced by 5 asterisks \"*****\".\n\nPhone number:\n\nA phone number is formatted as follows:\n\n- The phone number contains 10-13 digits.\n- The last 10 digits make up the local number.\n- The remaining 0-3 digits, in the beginning, make up the country code.\n- Separation characters from the set {'+', '-', '(', ')', ' '} separate the above digits in some way.\n\nTo mask a phone number:\n\n- Remove all separation characters.\n- The masked phone number should have the form:\n - \"***-***-XXXX\" if the country code has 0 digits.\n - \"+*-***-***-XXXX\" if the country code has 1 digit.\n - \"+**-***-***-XXXX\" if the country code has 2 digits.\n - \"+***-***-***-XXXX\" if the country code has 3 digits.\n- \"XXXX\" is the last 4 digits of the local number.\n\nExample 1:\n\nInput: s = \"LeetCode@LeetCode.com\"\nOutput: \"l*****e@leetcode.com\"\nExplanation: s is an email address.\nThe name and domain are converted to lowercase, and the middle of the name is replaced by 5 asterisks.\n\nExample 2:\n\nInput: s = \"AB@qq.com\"\nOutput: \"a*****b@qq.com\"\nExplanation: s is an email address.\nThe name and domain are converted to lowercase, and the middle of the name is replaced by 5 asterisks.\nNote that even though \"ab\" is 2 characters, it still must have 5 asterisks in the middle.\n\nExample 3:\n\nInput: s = \"1(234)567-890\"\nOutput: \"***-***-7890\"\nExplanation: s is a phone number.\nThere are 10 digits, so the local number is 10 digits and the country code is 0 digits.\nThus, the resulting masked number is \"***-***-7890\".\n\nConstraints:\n\n- s is either a valid email or a phone number.\n- If s is an email:\n - 8 <= s.length <= 40\n - s consists of uppercase and lowercase English letters and exactly one '@' symbol and '.' symbol.\n- If s is a phone number:\n - 10 <= s.length <= 20\n - s consists of digits, spaces, and the symbols '(', ')', '-', and '+'.\n", "canonical_tests": {"language":

resulting image.\n\nTo flip an image horizontally means that each row of the image is reversed.\n\n- For example, flipping [1,1,0] horizontally results in [0,1,1].\n\nTo invert an image means that each 0 is replaced by 1, and each 1 is replaced by 0.\n\n- For example, inverting [0,1,1] results in [1,0,0].\n\nExample 1:\n\nInput: image = [[1,1,0],[1,0,1],[0,0,0]]\nOutput: [[1,0,0],[0,1,0],[1,1,1]]\nExplanation: First reverse each row: [[0,1,1],[1,0,1],[0,0,0]].\nThen, invert the image: [[1,0,0],[0,1,0],[1,1,1]]\n\nExample 2:\n\nInput: image = [[1,1,0,0],[1,0,0,1],[0,1,1,1],[1,0,1,0]]\nOutput: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\nExplanation: First reverse each row: [[0,0,1,1],[1,0,0,1],[1,1,1,0],[0,1,0,1]].\nThen invert the image: [[1,1,0,0],[0,1,1,0],[0,0,0,1],[1,0,1,0]]\n\nConstraints:\n\n- n == image.length\n- n == image[i].length\n- 1 <= n <= 20\n- images[i][j] is either 0 or 1.\n", "canonical_tests": {"language": "python",

The replacement operations are given as three 0-indexed parallel arrays, indices, sources, and targets, all of length k.\n\nTo complete the i^th replacement operation:\n\n1. Check if the substring sources[i] occurs at index indices[i] in the original string s.\n2. If it does not occur, do nothing.\n3. Otherwise if it does occur, replace that substring with targets[i].\n\nFor example, if s = \"abcd\", indices[i] = 0, sources[i] = \"ab\", and targets[i] = \"eee\", then the result of this replacement will be \"eeecd\".\n\nAll replacement operations must occur simultaneously, meaning the replacement operations should not affect the indexing of each other. The testcases will be generated such that the replacements will not overlap.\n\n- For example, a testcase with s = \"abc\", indices = [0, 1], and sources = [\"ab\",\"bc\"] will not be generated because the \"ab\" and \"bc\" replacements overlap.\n\nReturn the resulting string after performing all replacement operations on s.\n\nA substring is a contiguous sequence of characters in a

[\"eee\",\"ffff\"]\nOutput: \"eeecd\"\nExplanation:\n\"ab\" occurs at index 0 in s, so we replace it with \"eee\".\n\"ec\" does not occur at index 2 in s, so we do nothing.\n\nConstraints:\n\n- 1 <= s.length <= 1000\n- k == indices.length == sources.length == targets.length\n- 1 <= k <= 100\n- 0 <= indexes[i] < s.length\n- 1 <= sources[i].length, targets[i].length <= 50\n- s consists of only

A binary matrix has only 0s and 1s as values.\n\nWe translate one image however we choose by sliding all the 1 bits left, right, up, and/or down any number of units. We then place it on top of the other image. We can then calculate the overlap by counting the number of positions that have a 1 in both images.\n\nNote also that a translation does not include any kind of rotation. Any 1 bits that are translated outside of the matrix borders are erased.\n\nReturn the largest possible overlap.\n\nExample 1:\n\nInput: img1 = [[1,1,0],[0,1,0],[0,1,0]], img2 = [[0,0,0],[0,1,1],[0,0,1]]\nOutput: 3\nExplanation: We translate img1 to right by 1 unit and down by 1 unit.\n\nThe number of positions that have a 1 in both images is 3 (shown in red).\n\nExample 2:\n\nInput: img1 = [[1]], img2 = [[1]]\nOutput: 1\n\nExample 3:\n\nInput: img1 = [[0]], img2 = [[0]]\nOutput: 0\n\nConstraints:\n\n- n == img1.length == img1[i].length\n- n == img2.length ==

Similarly, the dominoes falling to the right push their adjacent dominoes standing on the right.\n\nWhen a vertical domino has dominoes falling on it from both sides, it stays still due to the balance of the forces.\n\nFor the purposes of this question, we will consider that a falling domino expends no additional force to a falling or already fallen domino.\n\nYou are given a string dominoes representing the initial state where:\n\n- dominoes[i] = 'L', if the i^th domino has been pushed to the left,\n- dominoes[i] = 'R', if the i^th domino has been pushed to the right, and\n- dominoes[i] = '.', if the i^th domino has not been pushed.\n\nReturn a string representing the final state.\n\nExample 1:\n\nInput: dominoes = \"RR.L\"\nOutput: \"RR.L\"\nExplanation: The first domino expends no additional force on the second domino.\n\nExample 2:\n\nInput: dominoes = \".L.R...LR..L..\"\nOutput: \"LL.RR.LLRRLL..\"\n\nConstraints:\n\n- n == dominoes.length\n- 1 <= n <= 10^5\n- dominoes[i] is

key 1.\nWe then visit room 1 and pick up key 2.\nWe then visit room 2 and pick up key 3.\nWe then visit room 3.\nSince we were able to visit every room, we return true.\n\nExample 2:\n\nInput: rooms =

fits in a 32-bit signed integer type),\n- f.length >= 3, and\n- f[i] + f[i + 1] == f[i + 2] for all 0 <= i < f.length - 2.\n\nNote that when splitting the string into pieces, each piece must not have extra leading zeroes, except if the piece is the number 0 itself.\n\nReturn any Fibonacci-like sequence split from num, or return [] if it cannot be done.\n\nExample 1:\n\nInput: num =

impossible.\n\nExample 3:\n\nInput: num = \"0123\"\nOutput: []\nExplanation: Leading zeroes are not allowed, so \"01\", \"2\", \"3\" is not valid.\n\nConstraints:\n\n- 1 <= num.length <= 200\n- num

a person sitting in the i^th seat, and seats[i] = 0 represents that the i^th seat is empty (0-indexed).\n\nThere is at least one empty seat, and at least one person sitting.\n\nAlex wants to sit in the seat such that the distance between him and the closest person to him is maximized.\n\nReturn that maximum distance to the closest person.\n\nExample 1:\n\nInput: seats = [1,0,0,0,1,0,1]\nOutput: 2\nExplanation:\nIf Alex sits in the second open seat (i.e. seats[2]), then the closest person has distance 2.\nIf Alex sits in any other open seat, the closest person has distance 1.\nThus, the maximum distance to the closest person is 2.\n\nExample 2:\n\nInput: seats = [1,0,0,0]\nOutput: 3\nExplanation:\nIf Alex sits in the last seat (i.e. seats[3]), the closest person is 3 seats

All the given data in richer are logically correct (i.e., the data will not lead you to a situation where x is richer than y and y is richer than x at the same time).\n\nReturn an integer array answer where answer[x] = y if y is the least quiet person (that is, the person y with the smallest value of quiet[y]) among all people who definitely have equal to or more money than the person x.\n\nExample 1:\n\nInput: richer = [[1,0],[2,1],[3,1],[3,7],[4,3],[5,3],[6,3]], quiet = [3,2,5,4,6,1,7,0]\nOutput: [5,5,2,5,4,5,6,7]\nExplanation:\nanswer[0] = 5.\nPerson 5 has more money than 3, which has more money than 1, which has more money than 0.\nThe only person who is quieter (has lower quiet[x]) is person 7, but it is not clear if they have more money than person 0.\nanswer[7] = 7.\nAmong all people that definitely have equal to or more money than person 7 (which could be persons 3, 4, 5, 6, or 7), the person who is the quietest (has lower quiet[x]) is person 7.\nThe other answers can be filled out with similar reasoning.\n\nExample 2:\n\nInput: richer = [], quiet = [0]\nOutput: [0]\n\nConstraints:\n\n- n == quiet.length\n- 1 <= n <= 500\n- 0 <= quiet[i] < n\n- All the values of quiet are unique.\n- 0 <= richer.length <= n * (n - 1) / 2\n- 0 <= a_i, b_i < n\n- a_i!= b_i\n- All the pairs of richer are unique.\n- The observations in richer are all logically consistent.\n",

+{"question_id": 853, "task_id": "car-fleet", "difficulty": "Medium", "problem_description": "There are n cars at given miles away from the starting mile 0, traveling to reach the mile target.\n\nYou are given two integer arrays position and speed, both of length n, where position[i] is the starting mile of the i^th car and speed[i] is the speed of the i^th car in miles per hour.\n\nA car cannot pass another car, but it can catch up and then travel next to it at the speed of the slower car.\n\nA car fleet is a single car or a group of cars driving next to each other. The speed of the car fleet is the minimum speed of any car in the fleet.\n\nIf a car catches up to a car fleet at the mile target, it will still be considered as part of the car fleet.\n\nReturn the number of car fleets that will arrive at the destination.\n\nExample 1:\n\nInput: target = 12, position = [10,8,0,5,3], speed = [2,4,1,1,3]\nOutput: 3\nExplanation:\n- The cars starting at 10 (speed 2) and 8 (speed 4) become a fleet, meeting each other at 12. The fleet forms at target.\n- The car starting at 0 (speed 1) does not catch up to any other car, so it is a fleet by itself.\n- The cars starting at 5 (speed 1) and 3 (speed 3) become a fleet, meeting each other at 6. The fleet moves at speed 1 until it reaches target.\n\nExample 2:\n\nInput: target = 10, position = [3], speed = [3]\nOutput: 1\nExplanation:\nThere is only one car, hence there is only one fleet.\n\nExample 3:\n\nInput: target = 100, position = [0,2,4], speed = [4,2,1]\nOutput: 1\nExplanation:\n- The cars starting at 0 (speed 4) and 2 (speed 2) become a fleet, meeting each other at 4. The car starting at 4 (speed 1) travels to 5.\n- Then, the fleet at 4 (speed 2) and the car at position 5 (speed 1) become one fleet, meeting each other at 6. The fleet moves at speed 1 until it reaches target.\n\nConstraints:\n\n- n == position.length == speed.length\n- 1 <= n <= 10^5\n- 0 < target <= 10^6\n- 0 <= position[i] < target\n- All the values of position are unique.\n- 0 < speed[i] <= 10^6\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(target = 1000,position = [100, 200, 300],speed = [100,

Customers are standing in a queue to buy from you and order one at a time (in the order specified by bills). Each customer will only buy one lemonade and pay with either a $5, $10, or $20 bill. You must provide the correct change to each customer so that the net transaction is that the customer pays $5.\n\nNote that you do not have any change in hand at first.\n\nGiven an integer array bills where bills[i] is the bill the i^th customer pays, return true if you can provide every customer with the correct change, or false otherwise.\n\nExample 1:\n\nInput: bills = [5,5,5,10,20]\nOutput: true\nExplanation:\nFrom the first 3 customers, we collect three $5 bills in order.\nFrom the fourth customer, we collect a $10 bill and give back a $5.\nFrom the fifth customer, we give a $10 bill and a $5 bill.\nSince all customers got correct change, we output true.\n\nExample 2:\n\nInput: bills = [5,5,10,10,20]\nOutput: false\nExplanation:\nFrom the first two customers in order, we collect two $5 bills.\nFor the next two customers in order, we collect a $10 bill and give back a $5 bill.\nFor the last customer, we can not give the change of $15 back because we only have two $10 bills.\nSince not every customer received the correct change, the answer is false.\n\nConstraints:\n\n- 1 <= bills.length <= 10^5\n- bills[i] is either 5, 10, or 20.\n", "canonical_tests":

You cannot walk outside the grid, or walk into a wall.\n\nIf you walk over a key, you can pick it up and you cannot walk over a lock unless you have its corresponding key.\n\nFor some 1 <= k <= 6, there is exactly one lowercase and one uppercase letter of the first k letters of the English alphabet in the grid. This means that there is exactly one key for each lock, and one lock for each key; and also that the letters used to represent the keys and locks were chosen in the same order as the English alphabet.\n\nReturn the lowest number of moves to acquire all keys. If it is impossible, return -1.\n\nExample 1:\n\nInput: grid = [\"@.a..\",\"###.#\",\"b.A.B\"]\nOutput: 8\nExplanation: Note that the goal is to obtain all the keys not to open all the locks.\n\nExample 2:\n\nInput: grid = [\"@..aA\",\"..B#.\",\"....b\"]\nOutput: 6\n\nExample 3:\n\nInput: grid = [\"@Aa\"]\nOutput: -1\n\nConstraints:\n\n- m == grid.length\n- n == grid[i].length\n- 1 <= m, n <= 30\n- grid[i][j] is either an English letter, '.', '#', or '@'.\n- There is exactly one '@' in the grid.\n- The number of keys in the grid is in the range [1, 6].\n- Each key in the grid is

The gas stations are represented as an array stations where stations[i] = [position_i, fuel_i] indicates that the i^th gas station is position_i miles east of the starting position and has fuel_i liters of gas.\n\nThe car starts with an infinite tank of gas, which initially has startFuel liters of fuel in it. It uses one liter of gas per one mile that it drives. When the car reaches a gas station, it may stop and refuel, transferring all the gas from the station into the car.\n\nReturn the minimum number of refueling stops the car must make in order to reach its destination. If it cannot reach the destination, return -1.\n\nNote that if the car reaches a gas station with 0 fuel left, the car can still refuel there. If the car reaches the destination with 0 fuel left, it is still considered to have arrived.\n\nExample 1:\n\nInput: target = 1, startFuel = 1, stations = []\nOutput: 0\nExplanation: We can reach the target without refueling.\n\nExample 2:\n\nInput: target = 100, startFuel = 1, stations = [[10,100]]\nOutput: -1\nExplanation: We can not reach the target (or even the first gas station).\n\nExample 3:\n\nInput: target = 100, startFuel = 10, stations = [[10,60],[20,30],[30,30],[60,40]]\nOutput: 2\nExplanation: We start with 10 liters of fuel.\nWe drive to position 10, expending 10 liters of fuel. We refuel from 0 liters to 60 liters of gas.\nThen, we drive from position 10 to position 60 (expending 50 liters of fuel),\nand refuel from 10 liters to 50 liters of gas. We then drive to and reach the target.\nWe made 2 refueling stops along the way, so we return 2.\n\nConstraints:\n\n- 1 <= target, startFuel <= 10^9\n- 0 <= stations.length <= 500\n- 1 <= position_i <

+{"question_id": 874, "task_id": "walking-robot-simulation", "difficulty": "Medium", "problem_description": "A robot on an infinite XY-plane starts at point (0, 0) facing north. The robot receives an array of integers commands, which represents a sequence of moves that it needs to execute. There are only three possible types of instructions the robot can receive:\n\n- -2: Turn left 90 degrees.\n- -1: Turn right 90 degrees.\n- 1 <= k <= 9: Move forward k units, one unit at a time.\n\nSome of the grid squares are obstacles. The i^th obstacle is at grid point obstacles[i] = (x_i, y_i). If the robot runs into an obstacle, it will stay in its current location (on the block adjacent to the obstacle) and move onto the next command.\n\nReturn the maximum squared Euclidean distance that the robot reaches at any point in its path (i.e. if the distance is 5, return 25).\n\nNote:\n\n- There can be an obstacle at (0, 0). If this happens, the robot will ignore the obstacle until it has moved off the origin. However, it will be unable to return to (0, 0) due to the obstacle.\n- North means +Y direction.\n- East means +X direction.\n- South means -Y direction.\n- West means -X direction.\n\nExample 1:\n\nInput: commands = [4,-1,3], obstacles = []\nOutput: 25\nExplanation:\nThe robot starts at (0, 0):\n1. Move north 4 units to (0, 4).\n2. Turn right.\n3. Move east 3 units to (3, 4).\n\nThe furthest point the robot ever gets from the origin is (3, 4), which squared is 3^2 + 4^2= 25 units away.\n\nExample 2:\n\nInput: commands = [4,-1,4,-2,4], obstacles = [[2,4]]\nOutput: 65\nExplanation:\nThe robot starts at (0, 0):\n1. Move north 4 units to (0, 4).\n2. Turn right.\n3. Move east 1 unit and get blocked by the obstacle at (2, 4), robot is at (1, 4).\n4. Turn left.\n5. Move north 4 units to (1, 8).\n\nThe furthest point the robot ever gets from the origin is (1, 8), which squared is 1^2 + 8^2 = 65 units away.\n\nExample 3:\n\nInput: commands = [6,-1,-1,6], obstacles = [[0,0]]\nOutput: 36\nExplanation:\nThe robot starts at (0, 0):\n1. Move north 6 units to (0, 6).\n2. Turn right.\n3. Turn right.\n4. Move south 5 units and get blocked by the obstacle at (0,0), robot is at (0, 1).\n\nThe furthest point the robot ever gets from the origin is (0, 6), which squared is 6^2 = 36 units away.\n\nConstraints:\n\n- 1 <= commands.length <= 10^4\n- commands[i] is either -2, -1, or an integer in the range [1, 9].\n- 0 <= obstacles.length <= 10^4\n- -3 * 10^4 <= x_i, y_i <= 3 * 10^4\n- The

+{"question_id": 879, "task_id": "profitable-schemes", "difficulty": "Hard", "problem_description": "There is a group of n members, and a list of various crimes they could commit. The i^th crime generates a profit[i] and requires group[i] members to participate in it. If a member participates in one crime, that member can't participate in another crime.\n\nLet's call a profitable scheme any subset of these crimes that generates at least minProfit profit, and the total number of members participating in that subset of crimes is at most n.\n\nReturn the number of schemes that can be chosen. Since the answer may be very large, return it modulo 10^9 + 7.\n\nExample 1:\n\nInput: n = 5, minProfit = 3, group = [2,2], profit = [2,3]\nOutput: 2\nExplanation: To make a profit of at least 3, the group could either commit crimes 0 and 1, or just crime 1.\nIn total, there are 2 schemes.\n\nExample 2:\n\nInput: n = 10, minProfit = 5, group = [2,3,5], profit = [6,7,8]\nOutput: 7\nExplanation: To make a profit of at least 5, the group could commit any crimes, as long as they commit one.\nThere are 7 possible schemes: (0), (1), (2), (0,1), (0,2), (1,2), and (0,1,2).\n\nConstraints:\n\n- 1 <= n

To decode the string to a tape, the encoded string is read one character at a time and the following steps are taken:\n\n- If the character read is a letter, that letter is written onto the tape.\n- If the character read is a digit d, the entire current tape is repeatedly written d - 1 more times in total.\n\nGiven an integer k, return the k^th letter (1-indexed) in the decoded string.\n\nExample 1:\n\nInput: s = \"leet2code3\", k = 10\nOutput: \"o\"\nExplanation: The decoded string is \"leetleetcodeleetleetcodeleetleetcode\".\nThe 10^th letter in the string is \"o\".\n\nExample 2:\n\nInput: s = \"ha22\", k = 5\nOutput: \"h\"\nExplanation: The decoded string is \"hahahaha\".\nThe 5^th letter is \"h\".\n\nExample 3:\n\nInput: s = \"a2345678999999999999999\", k = 1\nOutput: \"a\"\nExplanation: The decoded string is \"a\" repeated 8301530446056247680 times.\nThe 1^st letter is \"a\".\n\nConstraints:\n\n- 2 <= s.length <= 100\n- s consists of lowercase English letters and digits 2 through 9.\n- s starts with a letter.\n- 1 <= k <= 10^9\n- It is guaranteed that k is less than or equal to the length of the decoded string.\n- The decoded string is guaranteed to have less

You decide to subdivide each edge in the graph into a chain of nodes, with the number of new nodes varying between each edge.\n\nThe graph is given as a 2D array of edges where edges[i] = [u_i, v_i, cnt_i] indicates that there is an edge between nodes u_i and v_i in the original graph, and cnt_i is the total number of new nodes that you will subdivide the edge into. Note that cnt_i == 0 means you will not subdivide the edge.\n\nTo subdivide the edge [u_i, v_i], replace it with (cnt_i + 1) new edges and cnt_i new nodes. The new nodes are x_1, x_2, ..., x_{cnt_i}, and the new edges are [u_i, x_1], [x_1, x_2], [x_2, x_3], ..., [x_{cnt_i-1}, x_{cnt_i}], [x_{cnt_i}, v_i].\n\nIn this new graph, you want to know how many nodes are reachable from the node 0, where a node is reachable if the distance is maxMoves or less.\n\nGiven the original graph and maxMoves, return the number of nodes that are reachable from node 0 in the new graph.\n\nExample 1:\n\nInput: edges = [[0,1,10],[0,2,1],[1,2,2]], maxMoves = 6, n = 3\nOutput: 13\nExplanation: The edge subdivisions are shown in the image above.\nThe nodes that are reachable are highlighted in yellow.\n\nExample 2:\n\nInput: edges = [[0,1,4],[1,2,6],[0,2,8],[1,3,1]], maxMoves = 10, n = 4\nOutput: 23\n\nExample 3:\n\nInput: edges = [[1,2,4],[1,4,5],[1,3,1],[2,3,4],[3,4,5]], maxMoves = 17, n = 5\nOutput: 1\nExplanation: Node 0 is disconnected from the rest of the graph, so only node 0 is reachable.\n\nConstraints:\n\n- 0 <= edges.length <= min(n * (n - 1) / 2, 10^4)\n- edges[i].length == 3\n- 0 <= u_i < v_i < n\n- There are no multiple edges in the graph.\n- 0 <= cnt_i <= 10^4\n- 0 <= maxMoves <= 10^9\n- 1 <= n <=

You may return the answer in any order.\n\nA word matches the pattern if there exists a permutation of letters p so that after replacing every letter x in the pattern with p(x), we get the desired word.\n\nRecall that a permutation of letters is a bijection from letters to letters: every letter maps to another letter, and no two letters map to the same letter.\n\nExample 1:\n\nInput: words = [\"abc\",\"deq\",\"mee\",\"aqq\",\"dkd\",\"ccc\"], pattern = \"abb\"\nOutput: [\"mee\",\"aqq\"]\nExplanation: \"mee\" matches the pattern because there is a permutation {a -> m, b -> e, ...}.\n\"ccc\" does not match the pattern because {a -> c, b -> c, ...} is not a permutation, since a and b map to the same letter.\n\nExample 2:\n\nInput: words = [\"a\",\"b\",\"c\"], pattern = \"a\"\nOutput: [\"a\",\"b\",\"c\"]\n\nConstraints:\n\n- 1 <= pattern.length <= 20\n- 1 <= words.length <= 50\n- words[i].length == pattern.length\n- pattern and words[i] are lowercase English letters.\n",

+{"question_id": 904, "task_id": "fruit-into-baskets", "difficulty": "Medium", "problem_description": "You are visiting a farm that has a single row of fruit trees arranged from left to right. The trees are represented by an integer array fruits where fruits[i] is the type of fruit the i^th tree produces.\n\nYou want to collect as much fruit as possible. However, the owner has some strict rules that you must follow:\n\n- You only have two baskets, and each basket can only hold a single type of fruit. There is no limit on the amount of fruit each basket can hold.\n- Starting from any tree of your choice, you must pick exactly one fruit from every tree (including the start tree) while moving to the right. The picked fruits must fit in one of your baskets.\n- Once you reach a tree with fruit that cannot fit in your baskets, you must stop.\n\nGiven the integer array fruits, return the maximum number of fruits you can pick.\n\nExample 1:\n\nInput: fruits = [1,2,1]\nOutput: 3\nExplanation: We can pick from all 3 trees.\n\nExample 2:\n\nInput: fruits = [0,1,2,2]\nOutput: 3\nExplanation: We can pick from trees [1,2,2].\nIf we had started at the first tree, we would only pick from trees [0,1].\n\nExample 3:\n\nInput: fruits = [1,2,3,2,2]\nOutput: 4\nExplanation: We can pick from trees [2,3,2,2].\nIf we had started at the first tree, we would only pick from trees [1,2].\n\nConstraints:\n\n- 1 <= fruits.length <= 10^5\n- 0 <= fruits[i] < fruits.length\n", "canonical_tests":

+{"question_id": 909, "task_id": "snakes-and-ladders", "difficulty": "Medium", "problem_description": "You are given an n x n integer matrix board where the cells are labeled from 1 to n^2 in a Boustrophedon style starting from the bottom left of the board (i.e. board[n - 1][0]) and alternating direction each row.\n\nYou start on square 1 of the board. In each move, starting from square curr, do the following:\n\n- Choose a destination square next with a label in the range [curr + 1, min(curr + 6, n^2)].\n - This choice simulates the result of a standard 6-sided die roll: i.e., there are always at most 6 destinations, regardless of the size of the board.\n- If next has a snake or ladder, you must move to the destination of that snake or ladder. Otherwise, you move to next.\n- The game ends when you reach the square n^2.\n\nA board square on row r and column c has a snake or ladder if board[r][c] != -1. The destination of that snake or ladder is board[r][c]. Squares 1 and n^2 are not the starting points of any snake or ladder.\n\nNote that you only take a snake or ladder at most once per dice roll. If the destination to a snake or ladder is the start of another snake or ladder, you do not follow the subsequent snake or ladder.\n\n- For example, suppose the board is [[-1,4],[-1,3]], and on the first move, your destination square is 2. You follow the ladder to square 3, but do not follow the subsequent ladder to 4.\n\nReturn the least number of dice rolls required to reach the square n^2. If it is not possible to reach the square, return -1.\n\nExample 1:\n\nInput: board = [[-1,-1,-1,-1,-1,-1],[-1,-1,-1,-1,-1,-1],[-1,-1,-1,-1,-1,-1],[-1,35,-1,-1,13,-1],[-1,-1,-1,-1,-1,-1],[-1,15,-1,-1,-1,-1]]\nOutput: 4\nExplanation:\nIn the beginning, you start at square 1 (at row 5, column 0).\nYou decide to move to square 2 and must take the ladder to square 15.\nYou then decide to move to square 17 and must take the snake to square 13.\nYou then decide to move to square 14 and must take the ladder to square 35.\nYou then decide to move to square 36, ending the game.\nThis is the lowest possible number of moves to reach the last square, so return 4.\n\nExample 2:\n\nInput: board = [[-1,-1],[-1,3]]\nOutput: 1\n\nConstraints:\n\n- n == board.length == board[i].length\n- 2 <= n <= 20\n- board[i][j] is either -1 or in the range [1, n^2].\n- The squares labeled 1 and n^2 are not the starting points of any snake or ladder.\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(board = [[-1, -1], [-1, 3]]) == 1\n assert

For example, if the Mouse is at node 1, it must travel to any node in graph[1].\n\nAdditionally, it is not allowed for the Cat to travel to the Hole (node 0).\n\nThen, the game can end in three ways:\n\n- If ever the Cat occupies the same node as the Mouse, the Cat wins.\n- If ever the Mouse reaches the Hole, the Mouse wins.\n- If ever a position is repeated (i.e., the players are in the same position as a previous turn, and it is the same player's turn to move), the game is a draw.\n\nGiven a graph, and assuming both players play optimally, return\n\n- 1 if the mouse wins the game,\n- 2 if the cat wins the game, or\n- 0 if the game is a draw.\n\nExample 1:\n\nInput: graph = [[2,5],[3],[0,4,5],[1,4,5],[2,3],[0,2,3]]\nOutput: 0\n\nExample 2:\n\nInput: graph = [[1,3],[0],[3],[0,2]]\nOutput: 1\n\nConstraints:\n\n- 3 <= graph.length <= 50\n- 1 <= graph[i].length < graph.length\n- 0 <= graph[i][j] < graph.length\n- graph[i][j] != i\n- graph[i] is unique.\n-

If multiple nodes could be removed to minimize M(initial), return such a node with the smallest index.\n\nNote that if a node was removed from the initial list of infected nodes, it might still be

Besides lowercase letters, the email may contain one or more '.' or '+'.\n\n- For example, in \"alice@leetcode.com\", \"alice\" is the local name, and \"leetcode.com\" is the domain name.\n\nIf you add periods '.' between some characters in the local name part of an email address, mail sent there will be forwarded to the same address without dots in the local name. Note that this rule does not apply to domain names.\n\n- For example, \"alice.z@leetcode.com\" and \"alicez@leetcode.com\" forward to the same email address.\n\nIf you add a plus '+' in the local name, everything after the first plus sign will be ignored. This allows certain emails to be filtered. Note that this rule does not apply to domain names.\n\n- For example, \"m.y+name@email.com\" will be forwarded to \"my@email.com\".\n\nIt is possible to use both of these rules at the same time.\n\nGiven an array of strings emails where we send one email to each emails[i], return the number of different addresses that actually receive mails.\n\nExample 1:\n\nInput: emails = [\"test.email+alex@leetcode.com\",\"test.e.mail+bob.cathy@leetcode.com\",\"testemail+david@lee.tcode.com\"]\nOutput: 2\nExplanation: \"testemail@leetcode.com\" and \"testemail@lee.tcode.com\" actually

emails[i] consist of lowercase English letters, '+', '.' and '@'.\n- Each emails[i] contains exactly one '@' character.\n- All local and domain names are non-empty.\n- Local names do not start with a

Each coordinate point may have at most one stone.\n\nA stone can be removed if it shares either the same row or the same column as another stone that has not been removed.\n\nGiven an array stones of length n where stones[i] = [x_i, y_i] represents the location of the i^th stone, return the largest possible number of stones that can be removed.\n\nExample 1:\n\nInput: stones = [[0,0],[0,1],[1,0],[1,2],[2,1],[2,2]]\nOutput: 5\nExplanation: One way to remove 5 stones is as follows:\n1. Remove stone [2,2] because it shares the same row as [2,1].\n2. Remove stone [2,1] because it shares the same column as [0,1].\n3. Remove stone [1,2] because it shares the same row as [1,0].\n4. Remove stone [1,0] because it shares the same column as [0,0].\n5. Remove stone [0,1] because it shares the same row as [0,0].\nStone [0,0] cannot be removed since it does not share a row/column with another stone still on the plane.\n\nExample 2:\n\nInput: stones = [[0,0],[0,2],[1,1],[2,0],[2,2]]\nOutput: 3\nExplanation: One way to make 3 moves is as follows:\n1. Remove stone [2,2] because it shares the same row as [2,0].\n2. Remove stone [2,0] because it shares the same column as [0,0].\n3. Remove stone [0,2] because it shares the same row as [0,0].\nStones [0,0] and [1,1] cannot be removed since they do not share a row/column with another stone still on the plane.\n\nExample 3:\n\nInput: stones = [[0,0]]\nOutput: 0\nExplanation: [0,0] is the only stone on the plane, so you cannot remove it.\n\nConstraints:\n\n- 1 <= stones.length <= 1000\n- 0 <= x_i, y_i <= 10^4\n- No two

+{"question_id": 948, "task_id": "bag-of-tokens", "difficulty": "Medium", "problem_description": "You start with an initial power of power, an initial score of 0, and a bag of tokens given as an integer array tokens, where each tokens[i] denotes the value of token_i.\n\nYour goal is to maximize the total score by strategically playing these tokens. In one move, you can play an unplayed token in one of the two ways (but not both for the same token):\n\n- Face-up: If your current power is at least tokens[i], you may play token_i, losing tokens[i] power and gaining 1 score.\n- Face-down: If your current score is at least 1, you may play token_i, gaining tokens[i] power and losing 1 score.\n\nReturn the maximum possible score you can achieve after playing any number of tokens.\n\nExample 1:\n\nInput: tokens = [100], power = 50\nOutput: 0\nExplanation: Since your score is 0 initially, you cannot play the token face-down. You also cannot play it face-up since your power (50) is less than tokens[0] (100).\n\nExample 2:\n\nInput: tokens = [200,100], power = 150\nOutput: 1\nExplanation: Play token_1 (100) face-up, reducing your power to 50 and increasing your score to 1.\nThere is no need to play token_0, since you cannot play it face-up to add to your score. The maximum score achievable is 1.\n\nExample 3:\n\nInput: tokens = [100,200,300,400], power = 200\nOutput: 2\nExplanation: Play the tokens in this order to get a score of 2:\n1. Play token_0 (100) face-up, reducing power to 100 and increasing score to 1.\n2. Play token_3 (400) face-down, increasing power to 500 and reducing score to 0.\n3. Play token_1 (200) face-up, reducing power to 300 and increasing score to 1.\n4. Play token_2 (300) face-up, reducing power to 0 and increasing score to 2.\n\nThe maximum score achievable is 2.\n\nConstraints:\n\n- 0 <= tokens.length <= 1000\n- 0 <= tokens[i], power < 10^4\n",

According to lexicographical rules \"apple\" > \"app\", because 'l' > '∅', where '∅' is defined as the blank character which is less than any other character (More info).\n\nConstraints:\n\n- 1 <=

For example, with x = 3, we might write 3 * 3 / 3 + 3 - 3 which is a value of 3.\n\nWhen writing such an expression, we adhere to the following conventions:\n\n- The division operator (/) returns rational numbers.\n- There are no parentheses placed anywhere.\n- We use the usual order of operations: multiplication and division happen before addition and subtraction.\n- It is not allowed to use the unary negation operator (-). For example, \"x - x\" is a valid expression as it only uses subtraction, but \"-x + x\" is not because it uses negation.\n\nWe would like to write an expression with the least number of operators such that the expression equals the given target. Return the least number of operators used.\n\nExample 1:\n\nInput: x = 3, target = 19\nOutput: 5\nExplanation: 3 * 3 + 3 * 3 + 3 / 3.\nThe expression contains 5 operations.\n\nExample 2:\n\nInput: x = 5, target = 501\nOutput: 8\nExplanation: 5 * 5 * 5 * 5 - 5 * 5 * 5 + 5 / 5.\nThe expression contains 8 operations.\n\nExample 3:\n\nInput: x = 100, target = 100000000\nOutput: 3\nExplanation: 100 * 100 * 100 * 100.\nThe expression contains 3 operations.\n\nConstraints:\n\n- 2 <= x <= 100\n- 1 <= target <= 2 * 10^8\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n

+{"question_id": 966, "task_id": "vowel-spellchecker", "difficulty": "Medium", "problem_description": "Given a wordlist, we want to implement a spellchecker that converts a query word into a correct word.\n\nFor a given query word, the spell checker handles two categories of spelling mistakes:\n\n- Capitalization: If the query matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the case in the wordlist.\n - Example: wordlist = [\"yellow\"], query = \"YellOw\": correct = \"yellow\"\n - Example: wordlist = [\"Yellow\"], query = \"yellow\": correct = \"Yellow\"\n - Example: wordlist = [\"yellow\"], query = \"yellow\": correct = \"yellow\"\n- Vowel Errors: If after replacing the vowels ('a', 'e', 'i', 'o', 'u') of the query word with any vowel individually, it matches a word in the wordlist (case-insensitive), then the query word is returned with the same case as the match in the wordlist.\n - Example: wordlist = [\"YellOw\"], query = \"yollow\": correct = \"YellOw\"\n - Example: wordlist = [\"YellOw\"], query = \"yeellow\": correct = \"\" (no match)\n - Example: wordlist = [\"YellOw\"], query = \"yllw\": correct = \"\" (no match)\n\nIn addition, the spell checker operates under the following precedence rules:\n\n- When the query exactly matches a word in the wordlist (case-sensitive), you should return the same word back.\n- When the query matches a word up to capitalization, you should return the first such match in the wordlist.\n- When the query matches a word up to vowel errors, you should return the first such match in the wordlist.\n- If the query has no matches in the wordlist, you should return the empty string.\n\nGiven some queries, return a list of words answer, where answer[i] is the correct word for query = queries[i].\n\nExample 1:\n\nInput: wordlist = [\"KiTe\",\"kite\",\"hare\",\"Hare\"], queries = [\"kite\",\"Kite\",\"KiTe\",\"Hare\",\"HARE\",\"Hear\",\"hear\",\"keti\",\"keet\",\"keto\"]\nOutput: [\"kite\",\"KiTe\",\"KiTe\",\"Hare\",\"hare\",\"\",\"\",\"KiTe\",\"\",\"KiTe\"]\n\nExample 2:\n\nInput: wordlist = [\"yellow\"], queries = [\"YellOw\"]\nOutput: [\"yellow\"]\n\nConstraints:\n\n- 1 <= wordlist.length, queries.length <= 5000\n- 1 <= wordlist[i].length, queries[i].length <=

other answers, such as [3, 3], would also be accepted.\n\nConstraints:\n\n- 1 <= arr.length <= 100\n- 1 <= arr[i] <= arr.length\n- All integers in arr are unique (i.e. arr is a permutation of the

The strings may use parentheses to denote the repeating part of the rational number.\n\nA rational number can be represented using up to three parts: , , and a . The number will be represented in one of the following three ways:\n\n- \n - For example, 12, 0, and 123.\n- <.>\n - For example, 0.5, 1., 2.12, and 123.0001.\n- <.><(><)>\n - For example, 0.1(6), 1.(9), 123.00(1212).\n\nThe repeating portion of a decimal expansion is conventionally denoted within a pair of round brackets. For example:\n\n- 1/6 = 0.16666666... = 0.1(6) = 0.1666(6) = 0.166(66).\n\nExample 1:\n\nInput: s = \"0.(52)\", t = \"0.5(25)\"\nOutput: true\nExplanation: Because \"0.(52)\" represents 0.52525252..., and \"0.5(25)\" represents 0.52525252525..... , the strings represent the same number.\n\nExample 2:\n\nInput: s = \"0.1666(6)\", t = \"0.166(66)\"\nOutput: true\n\nExample 3:\n\nInput: s = \"0.9(9)\", t = \"1.\"\nOutput: true\nExplanation: \"0.9(9)\" represents 0.999999999... repeated forever, which equals 1. [See this link for an explanation.]\n\"1.\" represents the number 1, which is formed correctly: (IntegerPart) = \"1\" and (NonRepeatingPart) = \"\".\n\nConstraints:\n\n- Each part consists only of digits.\n- The does not have leading zeros (except for the zero itself).\n- 1 <= .length <= 4\n- 0 <= .length <= 4\n- 1 <= .length <= 4\n", "canonical_tests": {"language": "python", "source": "def

+{"question_id": 975, "task_id": "odd-even-jump", "difficulty": "Hard", "problem_description": "You are given an integer array arr. From some starting index, you can make a series of jumps. The (1^st, 3^rd, 5^th, ...) jumps in the series are called odd-numbered jumps, and the (2^nd, 4^th, 6^th, ...) jumps in the series are called even-numbered jumps. Note that the jumps are numbered, not the indices.\n\nYou may jump forward from index i to index j (with i < j) in the following way:\n\n- During odd-numbered jumps (i.e., jumps 1, 3, 5, ...), you jump to the index j such that arr[i] <= arr[j] and arr[j] is the smallest possible value. If there are multiple such indices j, you can only jump to the smallest such index j.\n- During even-numbered jumps (i.e., jumps 2, 4, 6, ...), you jump to the index j such that arr[i] >= arr[j] and arr[j] is the largest possible value. If there are multiple such indices j, you can only jump to the smallest such index j.\n- It may be the case that for some index i, there are no legal jumps.\n\nA starting index is good if, starting from that index, you can reach the end of the array (index arr.length - 1) by jumping some number of times (possibly 0 or more than once).\n\nReturn the number of good starting indices.\n\nExample 1:\n\nInput: arr = [10,13,12,14,15]\nOutput: 2\nExplanation:\nFrom starting index i = 0, we can make our 1st jump to i = 2 (since arr[2] is the smallest among arr[1], arr[2], arr[3], arr[4] that is greater or equal to arr[0]), then we cannot jump any more.\nFrom starting index i = 1 and i = 2, we can make our 1st jump to i = 3, then we cannot jump any more.\nFrom starting index i = 3, we can make our 1st jump to i = 4, so we have reached the end.\nFrom starting index i = 4, we have reached the end already.\nIn total, there are 2 different starting indices i = 3 and i = 4, where we can reach the end with some number of\njumps.\n\nExample 2:\n\nInput: arr = [2,3,1,1,4]\nOutput: 3\nExplanation:\nFrom starting index i = 0, we make jumps to i = 1, i = 2, i = 3:\nDuring our 1st jump (odd-numbered), we first jump to i = 1 because arr[1] is the smallest value in [arr[1], arr[2], arr[3], arr[4]] that is greater than or equal to arr[0].\nDuring our 2nd jump (even-numbered), we jump from i = 1 to i = 2 because arr[2] is the largest value in [arr[2], arr[3], arr[4]] that is less than or equal to arr[1]. arr[3] is also the largest value, but 2 is a smaller index, so we can only jump to i = 2 and not i = 3\nDuring our 3rd jump (odd-numbered), we jump from i = 2 to i = 3 because arr[3] is the smallest value in [arr[3], arr[4]] that is greater than or equal to arr[2].\nWe can't jump from i = 3 to i = 4, so the starting index i = 0 is not good.\nIn a similar manner, we can deduce that:\nFrom starting index i = 1, we jump to i = 4, so we reach the end.\nFrom starting index i = 2, we jump to i = 3, and then we can't jump anymore.\nFrom starting index i = 3, we jump to i = 4, so we reach the end.\nFrom starting index i = 4, we are already at the end.\nIn total, there are 3 different starting indices i = 1, i = 3, and i = 4, where we can reach the end with some\nnumber of jumps.\n\nExample 3:\n\nInput: arr = [5,1,3,4,2]\nOutput: 3\nExplanation: We can reach the end from starting indices 1, 2, and 4.\n\nConstraints:\n\n- 1 <= arr.length <= 2 * 10^4\n- 0 <= arr[i] < 10^5\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

The days of the year in which you will travel are given as an integer array days. Each day is an integer from 1 to 365.\n\nTrain tickets are sold in three different ways:\n\n- a 1-day pass is sold for costs[0] dollars,\n- a 7-day pass is sold for costs[1] dollars, and\n- a 30-day pass is sold for costs[2] dollars.\n\nThe passes allow that many days of consecutive travel.\n\n- For example, if we get a 7-day pass on day 2, then we can travel for 7 days: 2, 3, 4, 5, 6, 7, and 8.\n\nReturn the minimum number of dollars you need to travel every day in the given list of days.\n\nExample 1:\n\nInput: days = [1,4,6,7,8,20], costs = [2,7,15]\nOutput: 11\nExplanation: For example, here is one way to buy passes that lets you travel your travel plan:\nOn day 1, you bought a 1-day pass for costs[0] = $2, which covered day 1.\nOn day 3, you bought a 7-day pass for costs[1] = $7, which covered days 3, 4, ..., 9.\nOn day 20, you bought a 1-day pass for costs[0] = $2, which covered day 20.\nIn total, you spent $11 and covered all the days of your travel.\n\nExample 2:\n\nInput: days = [1,2,3,4,5,6,7,8,9,10,30,31], costs = [2,7,15]\nOutput: 17\nExplanation: For example, here is one way to buy passes that lets you travel your travel plan:\nOn day 1, you bought a 30-day pass for costs[2] = $15 which covered days 1, 2, ..., 30.\nOn day 31, you bought a 1-day pass for costs[0] = $2 which covered day 31.\nIn total, you spent $17 and covered all the days of your travel.\n\nConstraints:\n\n- 1 <= days.length <= 365\n- 1 <= days[i] <= 365\n- days is in strictly increasing order.\n- costs.length == 3\n- 1 <= costs[i] <= 1000\n", "canonical_tests": {"language":

The i^th pile has stones[i] stones.\n\nA move consists of merging exactly k consecutive piles into one pile, and the cost of this move is equal to the total number of stones in these k piles.\n\nReturn the minimum cost to merge all piles of stones into one pile. If it is impossible, return -1.\n\nExample 1:\n\nInput: stones = [3,2,4,1], k = 2\nOutput: 20\nExplanation: We start with [3, 2, 4, 1].\nWe merge [3, 2] for a cost of 5, and we are left with [5, 4, 1].\nWe merge [4, 1] for a cost of 5, and we are left with [5, 5].\nWe merge [5, 5] for a cost of 10, and we are left with [10].\nThe total cost was 20, and this is the minimum possible.\n\nExample 2:\n\nInput: stones = [3,2,4,1], k = 3\nOutput: -1\nExplanation: After any merge operation, there are 2 piles left, and we can't merge anymore.

+{"question_id": 1001, "task_id": "grid-illumination", "difficulty": "Hard", "problem_description": "There is a 2D grid of size n x n where each cell of this grid has a lamp that is initially turned off.\n\nYou are given a 2D array of lamp positions lamps, where lamps[i] = [row_i, col_i] indicates that the lamp at grid[row_i][col_i] is turned on. Even if the same lamp is listed more than once, it is turned on.\n\nWhen a lamp is turned on, it illuminates its cell and all other cells in the same row, column, or diagonal.\n\nYou are also given another 2D array queries, where queries[j] = [row_j, col_j]. For the j^th query, determine whether grid[row_j][col_j] is illuminated or not. After answering the j^th query, turn off the lamp at grid[row_j][col_j] and its 8 adjacent lamps if they exist. A lamp is adjacent if its cell shares either a side or corner with grid[row_j][col_j].\n\nReturn an array of integers ans, where ans[j] should be 1 if the cell in the j^th query was illuminated, or 0 if the lamp was not.\n\nExample 1:\n\nInput: n = 5, lamps = [[0,0],[4,4]], queries = [[1,1],[1,0]]\nOutput: [1,0]\nExplanation: We have the initial grid with all lamps turned off. In the above picture we see the grid after turning on the lamp at grid[0][0] then turning on the lamp at grid[4][4].\nThe 0^th query asks if the lamp at grid[1][1] is illuminated or not (the blue square). It is illuminated, so set ans[0] = 1. Then, we turn off all lamps in the red square.\n\nThe 1^st query asks if the lamp at grid[1][0] is illuminated or not (the blue square). It is not illuminated, so set ans[1] = 0. Then, we turn off all lamps in the red rectangle.\n\nExample 2:\n\nInput: n = 5, lamps = [[0,0],[4,4]], queries = [[1,1],[1,1]]\nOutput: [1,1]\n\nExample 3:\n\nInput: n = 5, lamps = [[0,0],[0,4]],

These video clips can be overlapping with each other and have varying lengths.\n\nEach video clip is described by an array clips where clips[i] = [start_i, end_i] indicates that the ith clip started at start_i and ended at end_i.\n\nWe can cut these clips into segments freely.\n\n- For example, a clip [0, 7] can be cut into segments [0, 1] + [1, 3] + [3, 7].\n\nReturn the minimum number of clips needed so that we can cut the clips into segments that cover the entire sporting event [0, time]. If the task is impossible, return -1.\n\nExample 1:\n\nInput: clips = [[0,2],[4,6],[8,10],[1,9],[1,5],[5,9]], time = 10\nOutput: 3\nExplanation: We take the clips [0,2], [8,10], [1,9]; a total of 3 clips.\nThen, we can reconstruct the sporting event as follows:\nWe cut [1,9] into segments [1,2] + [2,8] + [8,9].\nNow we have segments [0,2] + [2,8] + [8,10] which cover the sporting event [0, 10].\n\nExample 2:\n\nInput: clips = [[0,1],[1,2]], time = 5\nOutput: -1\nExplanation: We cannot cover [0,5] with only [0,1] and [1,2].\n\nExample 3:\n\nInput: clips =

There is a rows x cols matrix and you are on the cell with the coordinates (rCenter, cCenter).\n\nReturn the coordinates of all cells in the matrix, sorted by their distance from (rCenter, cCenter) from the smallest distance to the largest distance. You may return the answer in any order that satisfies this condition.\n\nThe distance between two cells (r_1, c_1) and (r_2, c_2) is |r_1 - r_2| + |c_1 - c_2|.\n\nExample 1:\n\nInput: rows = 1, cols = 2, rCenter = 0, cCenter = 0\nOutput: [[0,0],[0,1]]\nExplanation: The distances from (0, 0) to other cells are: [0,1]\n\nExample 2:\n\nInput: rows = 2, cols = 2, rCenter = 0, cCenter = 1\nOutput: [[0,1],[0,0],[1,1],[1,0]]\nExplanation: The distances from (0, 1) to other cells are: [0,1,1,2]\nThe answer [[0,1],[1,1],[0,0],[1,0]] would also be accepted as correct.\n\nExample 3:\n\nInput: rows =

You are given three integers a, b, and c, the positions of the stones.\n\nIn one move, you pick up a stone at an endpoint (i.e., either the lowest or highest position stone), and move it to an unoccupied position between those endpoints. Formally, let's say the stones are currently at positions x, y, and z with x < y < z. You pick up the stone at either position x or position z, and move that stone to an integer position k, with x < k < z and k != y.\n\nThe game ends when you cannot make any more moves (i.e., the stones are in three consecutive positions).\n\nReturn an integer array answer of length 2 where:\n\n- answer[0] is the minimum number of moves you can play, and\n- answer[1] is the maximum number of moves you can play.\n\nExample 1:\n\nInput: a = 1, b = 2, c = 5\nOutput: [1,2]\nExplanation: Move the stone from 5 to 3, or move the stone from 5 to 4 to 3.\n\nExample 2:\n\nInput: a = 4, b = 3, c =

You are given an integer array stones, the positions of the stones.\n\nCall a stone an endpoint stone if it has the smallest or largest position. In one move, you pick up an endpoint stone and move it to an unoccupied position so that it is no longer an endpoint stone.\n\n- In particular, if the stones are at say, stones = [1,2,5], you cannot move the endpoint stone at position 5, since moving it to any position (such as 0, or 3) will still keep that stone as an endpoint stone.\n\nThe game ends when you cannot make any more moves (i.e., the stones are in three consecutive positions).\n\nReturn an integer array answer of length 2 where:\n\n- answer[0] is the minimum number of moves you can play, and\n- answer[1] is the maximum number of moves you can play.\n\nExample 1:\n\nInput: stones = [7,4,9]\nOutput: [1,2]\nExplanation: We can move 4 -> 8 for one move to finish the game.\nOr, we can move 9 -> 5, 4 -> 6 for two moves to finish the game.\n\nExample 2:\n\nInput: stones = [6,5,4,3,10]\nOutput: [2,3]\nExplanation: We can move 3 -> 8 then 10 -> 7 to finish the game.\nOr, we can move 3 -> 7, 4 -> 8, 5 -> 9 to finish the game.\nNotice we cannot move 10 -> 2 to finish the game, because that would be an illegal move.\n\nConstraints:\n\n- 3 <= stones.length <= 10^4\n- 1 <= stones[i] <= 10^9\n- All the values of stones

Each heights[i] is the height of the i^th student in line (0-indexed).\n\nReturn the number of indices where heights[i] != expected[i].\n\nExample 1:\n\nInput: heights = [1,1,4,2,1,3]\nOutput: 3\nExplanation:\nheights: [1,1,4,2,1,3]\nexpected: [1,1,1,2,3,4]\nIndices 2, 4, and 5 do not match.\n\nExample 2:\n\nInput: heights = [5,1,2,3,4]\nOutput: 5\nExplanation:\nheights: [5,1,2,3,4]\nexpected: [1,2,3,4,5]\nAll indices do not match.\n\nExample 3:\n\nInput: heights = [1,2,3,4,5]\nOutput: 0\nExplanation:\nheights: [1,2,3,4,5]\nexpected: [1,2,3,4,5]\nAll indices match.\n\nConstraints:\n\n- 1 <= heights.length <= 100\n- 1 <= heights[i] <= 100\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(heights = [1]) == 0\n

+{"question_id": 1061, "task_id": "lexicographically-smallest-equivalent-string", "difficulty": "Medium", "problem_description": "You are given two strings of the same length s1 and s2 and a string baseStr.\n\nWe say s1[i] and s2[i] are equivalent characters.\n\n- For example, if s1 = \"abc\" and s2 = \"cde\", then we have 'a' == 'c', 'b' == 'd', and 'c' == 'e'.\n\nEquivalent characters follow the usual rules of any equivalence relation:\n\n- Reflexivity: 'a' == 'a'.\n- Symmetry: 'a' == 'b' implies 'b' == 'a'.\n- Transitivity: 'a' == 'b' and 'b' == 'c' implies 'a' == 'c'.\n\nFor example, given the equivalency information from s1 = \"abc\" and s2 = \"cde\", \"acd\" and \"aab\" are equivalent strings of baseStr = \"eed\", and \"aab\" is the lexicographically smallest equivalent string of baseStr.\n\nReturn the lexicographically smallest equivalent string of baseStr by using the equivalency information from s1 and s2.\n\nExample 1:\n\nInput: s1 = \"parker\", s2 = \"morris\", baseStr = \"parser\"\nOutput: \"makkek\"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [m,p], [a,o], [k,r,s], [e,i].\nThe characters in each group are equivalent and sorted in lexicographical order.\nSo the answer is \"makkek\".\n\nExample 2:\n\nInput: s1 = \"hello\", s2 = \"world\", baseStr = \"hold\"\nOutput: \"hdld\"\nExplanation: Based on the equivalency information in s1 and s2, we can group their characters as [h,w], [d,e,o], [l,r].\nSo only the second letter 'o' in baseStr is changed to 'd', the answer is \"hdld\".\n\nExample 3:\n\nInput: s1 = \"leetcode\", s2 = \"programs\", baseStr = \"sourcecode\"\nOutput: \"aauaaaaada\"\nExplanation: We group the equivalent characters in s1 and s2 as [a,o,e,r,s,c], [l,p], [g,t] and [d,m], thus all letters in baseStr except 'u' and 'd' are transformed to 'a', the answer is \"aauaaaaada\".\n\nConstraints:\n\n- 1 <= s1.length, s2.length, baseStr <= 1000\n- s1.length == s2.length\n-

+{"question_id": 1094, "task_id": "car-pooling", "difficulty": "Medium", "problem_description": "There is a car with capacity empty seats. The vehicle only drives east (i.e., it cannot turn around and drive west).\n\nYou are given the integer capacity and an array trips where trips[i] = [numPassengers_i, from_i, to_i] indicates that the i^th trip has numPassengers_i passengers and the locations to pick them up and drop them off are from_i and to_i respectively. The locations are given as the number of kilometers due east from the car's initial location.\n\nPassengers are dropped off before new passengers are picked up at the same location. At every point along the route, the total number of passengers in the car must not exceed capacity.\n\nReturn true if it is possible to pick up and drop off all passengers for all the given trips, or false otherwise.\n\nExample 1:\n\nInput: trips = [[2,1,5],[3,3,7]], capacity = 4\nOutput: false\nExplanation:\nAt kilometer 1, 2 passengers are picked up, so the car holds 2.\nAt kilometer 3, 3 more are picked up, so the car holds 5.\nSince 5 > capacity = 4, the trips cannot all be completed.\n\nExample 2:\n\nInput: trips = [[2,1,5],[3,3,7]], capacity = 5\nOutput: true\nExplanation:\nAt kilometer 1, the car holds 2 passengers.\nAt kilometer 3, the car holds 5 passengers.\nAt kilometer 5, the first 2 are dropped off, so the car holds 3.\nAt kilometer 7, the last 3 are dropped off, so the car holds 0.\nThe maximum occupancy is 5, which never exceeds capacity = 5.\n\nConstraints:\n\n- 1 <= trips.length <= 1000\n- trips[i].length == 3\n- 1 <= numPassengers_i <= 100\n- 0 <= from_i < to_i <= 1000\n- 1 <= capacity <= 10^5\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(trips = [[3, 2, 8], [4, 4, 6], [10, 8, 10]],capacity = 12) == True\n

+{"question_id": 1096, "task_id": "brace-expansion-ii", "difficulty": "Hard", "problem_description": "Under the grammar given below, strings can represent a set of lowercase words. Let R(expr) denote the set of words the expression represents.\n\nThe grammar can best be understood through simple examples:\n\n- Single letters represent a singleton set containing that word.\n - R(\"a\") = {\"a\"}\n - R(\"w\") = {\"w\"}\n- When we take a comma-delimited list of two or more expressions, we take the union of possibilities.\n - R(\"{a,b,c}\") = {\"a\",\"b\",\"c\"}\n - R(\"{{a,b},{b,c}}\") = {\"a\",\"b\",\"c\"} (notice the final set only contains each word at most once)\n- When we concatenate two expressions, we take the set of possible concatenations between two words where the first word comes from the first expression and the second word comes from the second expression.\n - R(\"{a,b}{c,d}\") = {\"ac\",\"ad\",\"bc\",\"bd\"}\n - R(\"a{b,c}{d,e}f{g,h}\") = {\"abdfg\", \"abdfh\", \"abefg\", \"abefh\", \"acdfg\", \"acdfh\", \"acefg\", \"acefh\"}\n\nFormally, the three rules for our grammar:\n\n- For every lowercase letter x, we have R(x) = {x}.\n- For expressions e_1, e_2, ... , e_k with k >= 2, we have R({e_1, e_2, ...}) = R(e_1) ∪ R(e_2) ∪ ...\n- For expressions e_1 and e_2, we have R(e_1 + e_2) = {a + b for (a, b) in R(e_1) × R(e_2)}, where + denotes concatenation, and × denotes the cartesian product.\n\nGiven an expression representing a set of words under the given grammar, return the sorted list of words that the expression represents.\n\nExample 1:\n\nInput: expression = \"{a,b}{c,{d,e}}\"\nOutput: [\"ac\",\"ad\",\"ae\",\"bc\",\"bd\",\"be\"]\n\nExample 2:\n\nInput: expression = \"{{a,z},a{b,c},{ab,z}}\"\nOutput: [\"a\",\"ab\",\"ac\",\"z\"]\nExplanation: Each distinct word is written only once in the final answer.\n\nConstraints:\n\n- 1 <= expression.length <= 60\n- expression[i] consists of '{', '}', ','or lowercase English letters.\n- The given expression represents a set of words based on the grammar given in the description.\n", "canonical_tests": {"language": "python", "source": "def

+{"question_id": 1103, "task_id": "distribute-candies-to-people", "difficulty": "Easy", "problem_description": "We distribute some number of candies, to a row of n = num_people people in the following way:\n\nWe then give 1 candy to the first person, 2 candies to the second person, and so on until we give n candies to the last person.\n\nThen, we go back to the start of the row, giving n + 1 candies to the first person, n + 2 candies to the second person, and so on until we give 2 * n candies to the last person.\n\nThis process repeats (with us giving one more candy each time, and moving to the start of the row after we reach the end) until we run out of candies. The last person will receive all of our remaining candies (not necessarily one more than the previous gift).\n\nReturn an array (of length num_people and sum candies) that represents the final distribution of candies.\n\nExample 1:\n\nInput: candies = 7, num_people = 4\nOutput: [1,2,3,1]\nExplanation:\nOn the first turn, ans[0] += 1, and the array is [1,0,0,0].\nOn the second turn, ans[1] += 2, and the array is [1,2,0,0].\nOn the third turn, ans[2] += 3, and the array is [1,2,3,0].\nOn the fourth turn, ans[3] += 1 (because there is only one candy left), and the final array is [1,2,3,1].\n\nExample 2:\n\nInput: candies = 10, num_people = 3\nOutput: [5,2,3]\nExplanation:\nOn the first turn, ans[0] += 1, and the array is [1,0,0].\nOn the second turn, ans[1] += 2, and the

You are also given an integer shelfWidth.\n\nWe want to place these books in order onto bookcase shelves that have a total width shelfWidth.\n\nWe choose some of the books to place on this shelf such that the sum of their thickness is less than or equal to shelfWidth, then build another level of the shelf of the bookcase so that the total height of the bookcase has increased by the maximum height of the books we just put down. We repeat this process until there are no more books to place.\n\nNote that at each step of the above process, the order of the books we place is the same order as the given sequence of books.\n\n- For example, if we have an ordered list of 5 books, we might place the first and second book onto the first shelf, the third book on the second shelf, and the fourth and fifth book on the last shelf.\n\nReturn the minimum possible height that the total bookshelf can be after placing shelves in this manner.\n\nExample 1:\n\nInput: books = [[1,1],[2,3],[2,3],[1,1],[1,1],[1,1],[1,2]],

It can be in one of the following shapes:\n\n- 't' that evaluates to true.\n- 'f' that evaluates to false.\n- '!(subExpr)' that evaluates to the logical NOT of the inner expression subExpr.\n- '&(subExpr_1, subExpr_2, ..., subExpr_n)' that evaluates to the logical AND of the inner expressions subExpr_1, subExpr_2, ..., subExpr_n where n >= 1.\n- '|(subExpr_1, subExpr_2, ..., subExpr_n)' that evaluates to the logical OR of the inner expressions subExpr_1, subExpr_2, ..., subExpr_n where n >= 1.\n\nGiven a string expression that represents a boolean expression, return the evaluation of that expression.\n\nIt is guaranteed that the given expression is valid and follows the given rules.\n\nExample 1:\n\nInput: expression = \"&(|(f))\"\nOutput: false\nExplanation:\nFirst, evaluate |(f) --> f. The expression is now \"&(f)\".\nThen, evaluate &(f) --> f. The expression is now \"f\".\nFinally, return false.\n\nExample 2:\n\nInput: expression = \"|(f,f,f,t)\"\nOutput: true\nExplanation: The evaluation of (false OR false OR false OR true) is true.\n\nExample 3:\n\nInput: expression = \"!(&(f,t))\"\nOutput: true\nExplanation:\nFirst, evaluate &(f,t) --> (false AND true) --> false --> f.

+{"question_id": 1140, "task_id": "stone-game-ii", "difficulty": "Medium", "problem_description": "Alice and Bob continue their games with piles of stones. There are a number of piles arranged in a row, and each pile has a positive integer number of stones piles[i]. The objective of the game is to end with the most stones.\n\nAlice and Bob take turns, with Alice starting first.\n\nOn each player's turn, that player can take all the stones in the first X remaining piles, where 1 <= X <= 2M. Then, we set M = max(M, X). Initially, M = 1.\n\nThe game continues until all the stones have been taken.\n\nAssuming Alice and Bob play optimally, return the maximum number of stones Alice can get.\n\nExample 1:\n\nInput: piles = [2,7,9,4,4]\nOutput: 10\nExplanation:\n- If Alice takes one pile at the beginning, Bob takes two piles, then Alice takes 2 piles again. Alice can get 2 + 4 + 4 = 10 stones in total.\n- If Alice takes two piles at the beginning, then Bob can take all three piles left. In this case, Alice get 2 + 7 = 9 stones in total.\n\nSo we return 10 since it's larger.\n\nExample 2:\n\nInput: piles = [1,2,3,4,5,100]\nOutput: 104\n\nConstraints:\n\n- 1 <= piles.length <= 100\n- 1

+{"question_id": 1210, "task_id": "minimum-moves-to-reach-target-with-rotations", "difficulty": "Hard", "problem_description": "In an n*n grid, there is a snake that spans 2 cells and starts moving from the top left corner at (0, 0) and (0, 1). The grid has empty cells represented by zeros and blocked cells represented by ones. The snake wants to reach the lower right corner at (n-1, n-2) and (n-1, n-1).\n\nIn one move the snake can:\n\n- Move one cell to the right if there are no blocked cells there. This move keeps the horizontal/vertical position of the snake as it is.\n- Move down one cell if there are no blocked cells there. This move keeps the horizontal/vertical position of the snake as it is.\n- Rotate clockwise if it's in a horizontal position and the two cells under it are both empty. In that case the snake moves from (r, c) and (r, c+1) to (r, c) and (r+1, c).\n- Rotate counterclockwise if it's in a vertical position and the two cells to its right are both empty. In that case the snake moves from (r, c) and (r+1, c) to (r, c) and (r, c+1).\n\nReturn the minimum number of moves to reach the target.\n\nIf there is no way to reach the target, return -1.\n\nExample 1:\n\nInput: grid = [[0,0,0,0,0,1],\n [1,1,0,0,1,0],\n [0,0,0,0,1,1],\n [0,0,1,0,1,0],\n [0,1,1,0,0,0],\n [0,1,1,0,0,0]]\nOutput: 11\nExplanation:\nOne possible solution is [right, right, rotate clockwise, right, down, down, down, down, rotate counterclockwise, right, down].\n\nExample 2:\n\nInput: grid = [[0,0,1,1,1,1],\n [0,0,0,0,1,1],\n [1,1,0,0,0,1],\n [1,1,1,0,0,1],\n [1,1,1,0,0,1],\n [1,1,1,0,0,0]]\nOutput: 9\n\nConstraints:\n\n- 2 <= n <= 100\n- 0 <= grid[i][j] <= 1\n- It is guaranteed that the snake starts at empty cells.\n", "canonical_tests": {"language":

For example, \"/a/b\" is a sub-folder of \"/a\", but \"/b\" is not a sub-folder of \"/a/b/c\".\n\nThe format of a path is one or more concatenated strings of the form: '/' followed by one or more lowercase English letters.\n\n- For example, \"/leetcode\" and \"/leetcode/problems\" are valid paths while an empty string and \"/\" are not.\n\nExample 1:\n\nInput: folder = [\"/a\",\"/a/b\",\"/c/d\",\"/c/d/e\",\"/c/f\"]\nOutput: [\"/a\",\"/c/d\",\"/c/f\"]\nExplanation: Folders \"/a/b\" is a subfolder of \"/a\" and \"/c/d/e\" is inside of folder \"/c/d\" in our filesystem.\n\nExample 2:\n\nInput: folder = [\"/a\",\"/a/b/c\",\"/a/b/d\"]\nOutput: [\"/a\"]\nExplanation: Folders \"/a/b/c\" and \"/a/b/d\" will be removed because they are subfolders of \"/a\".\n\nExample 3:\n\nInput: folder = [\"/a/b/c\",\"/a/b/ca\",\"/a/b/d\"]\nOutput: [\"/a/b/c\",\"/a/b/ca\",\"/a/b/d\"]\n\nConstraints:\n\n- 1 <= folder.length <= 4 * 10^4\n- 2 <= folder[i].length <= 100\n- folder[i] contains only lowercase letters and '/'.\n- folder[i] always starts with the character '/'.\n- Each folder name is unique.\n", "canonical_tests": {"language": "python", "source":

+{"question_id": 1263, "task_id": "minimum-moves-to-move-a-box-to-their-target-location", "difficulty": "Hard", "problem_description": "A storekeeper is a game in which the player pushes boxes around in a warehouse trying to get them to target locations.\n\nThe game is represented by an m x n grid of characters grid where each element is a wall, floor, or box.\n\nYour task is to move the box 'B' to the target position 'T' under the following rules:\n\n- The character 'S' represents the player. The player can move up, down, left, right in grid if it is a floor (empty cell).\n- The character '.' represents the floor which means a free cell to walk.\n- The character '#' represents the wall which means an obstacle (impossible to walk there).\n- There is only one box 'B' and one target cell 'T' in the grid.\n- The box can be moved to an adjacent free cell by standing next to the box and then moving in the direction of the box. This is a push.\n- The player cannot walk through the box.\n\nReturn the minimum number of pushes to move the box to the target. If there is no way to reach the target, return -1.\n\nExample 1:\n\nInput: grid = [[\"#\",\"#\",\"#\",\"#\",\"#\",\"#\"],\n [\"#\",\"T\",\"#\",\"#\",\"#\",\"#\"],\n [\"#\",\".\",\".\",\"B\",\".\",\"#\"],\n [\"#\",\".\",\"#\",\"#\",\".\",\"#\"],\n [\"#\",\".\",\".\",\".\",\"S\",\"#\"],\n [\"#\",\"#\",\"#\",\"#\",\"#\",\"#\"]]\nOutput: 3\nExplanation: We return only the number of times the box is pushed.\n\nExample 2:\n\nInput: grid = [[\"#\",\"#\",\"#\",\"#\",\"#\",\"#\"],\n [\"#\",\"T\",\"#\",\"#\",\"#\",\"#\"],\n [\"#\",\".\",\".\",\"B\",\".\",\"#\"],\n [\"#\",\"#\",\"#\",\"#\",\".\",\"#\"],\n [\"#\",\".\",\".\",\".\",\"S\",\"#\"],\n [\"#\",\"#\",\"#\",\"#\",\"#\",\"#\"]]\nOutput: -1\n\nExample 3:\n\nInput: grid =

[\"#\",\".\",\".\",\".\",\"S\",\"#\"],\n [\"#\",\"#\",\"#\",\"#\",\"#\",\"#\"]]\nOutput: 5\nExplanation: push the box down, left, left, up and up.\n\nConstraints:\n\n- m == grid.length\n- n ==

- move horizontally by one unit, or\n - move diagonally sqrt(2) units (in other words, move one unit vertically then one unit horizontally in 1 second).\n- You have to visit the points in the same

You are given four arrays: status, candies, keys, and containedBoxes where:\n\n- status[i] is 1 if the i^th box is open and 0 if the i^th box is closed,\n- candies[i] is the number of candies in the i^th box,\n- keys[i] is a list of the labels of the boxes you can open after opening the i^th box.\n- containedBoxes[i] is a list of the boxes you found inside the i^th box.\n\nYou are given an integer array initialBoxes that contains the labels of the boxes you initially have. You can take all the candies in any open box and you can use the keys in it to open new boxes and you also can use the boxes you find in it.\n\nReturn the maximum number of candies you can get following the rules above.\n\nExample 1:\n\nInput: status = [1,0,1,0], candies = [7,5,4,100], keys = [[],[],[1],[]], containedBoxes = [[1,2],[3],[],[]], initialBoxes = [0]\nOutput: 16\nExplanation: You will be initially given box 0. You will find 7 candies in it and boxes 1 and 2.\nBox 1 is closed and you do not have a key for it so you will open box 2. You will find 4 candies and a key to box 1 in box 2.\nIn box 1, you will find 5 candies and box 3 but you will not find a key to box 3 so box 3 will remain closed.\nTotal number of candies collected = 7 + 4 + 5 = 16 candy.\n\nExample 2:\n\nInput: status = [1,0,0,0,0,0], candies = [1,1,1,1,1,1], keys = [[1,2,3,4,5],[],[],[],[],[]], containedBoxes = [[1,2,3,4,5],[],[],[],[],[]], initialBoxes = [0]\nOutput: 6\nExplanation: You have initially box 0. Opening it you can find boxes 1,2,3,4 and 5 and their keys.\nThe total number of candies will be 6.\n\nConstraints:\n\n- n == status.length == candies.length == keys.length == containedBoxes.length\n-

side.\n\nYou need to check if the equation is solvable under the following rules:\n\n- Each character is decoded as one digit (0 - 9).\n- No two characters can map to the same digit.\n- Each words[i] and result are decoded as one number without leading zeros.\n- Sum of numbers on the left side (words) will equal to the number on the right side (result).\n\nReturn true if the equation is solvable,

each English uppercase letter is located at some coordinate.\n\n- For example, the letter 'A' is located at coordinate (0, 0), the letter 'B' is located at coordinate (0, 1), the letter 'P' is located at coordinate (2, 3) and the letter 'Z' is located at coordinate (4, 1).\n\nGiven the string word, return the minimum total distance to type such string using only two fingers.\n\nThe distance between coordinates (x_1, y_1) and (x_2, y_2) is |x_1 - x_2| + |y_1 - y_2|.\n\nNote that the initial positions of your two fingers are considered free so do not count towards your total distance, also your two fingers do not have to start at the first letter or the first two letters.\n\nExample 1:\n\nInput: word = \"CAKE\"\nOutput: 3\nExplanation: Using two fingers, one optimal way to type \"CAKE\" is:\nFinger 1 on letter 'C' -> cost = 0\nFinger 1 on letter 'A' -> cost = Distance from letter 'C' to letter 'A' = 2\nFinger 2 on letter 'K' -> cost = 0\nFinger 2 on letter 'E' -> cost = Distance from letter 'K' to letter 'E' = 1\nTotal distance = 3\n\nExample 2:\n\nInput: word = \"HAPPY\"\nOutput: 6\nExplanation: Using two fingers, one optimal way to type \"HAPPY\" is:\nFinger 1 on letter 'H' -> cost = 0\nFinger 1 on letter 'A' -> cost = Distance from letter 'H' to letter 'A' = 2\nFinger 2 on letter 'P' -> cost = 0\nFinger 2 on letter 'P' -> cost = Distance from letter 'P' to letter 'P' = 0\nFinger 1 on letter 'Y' -> cost = Distance from letter 'A' to letter 'Y' = 4\nTotal distance = 6\n\nConstraints:\n\n- 2 <= word.length <= 300\n- word consists of uppercase English letters.\n",

(0-indexed) means the i-th tap can water the area [i - ranges[i], i + ranges[i]] if it was open.\n\nReturn the minimum number of taps that should be open to water the whole garden, If the garden cannot be watered return -1.\n\nExample 1:\n\nInput: n = 5, ranges = [3,4,1,1,0,0]\nOutput: 1\nExplanation: The tap at point 0 can cover the interval [-3,3]\nThe tap at point 1 can cover the interval [-3,5]\nThe tap at point 2 can cover the interval [1,3]\nThe tap at point 3 can cover the interval [2,4]\nThe tap at point 4 can cover the interval [4,4]\nThe tap at point 5 can cover the interval [5,5]\nOpening Only the second tap will water the whole garden [0,5]\n\nExample 2:\n\nInput: n = 3, ranges = [0,0,0,0]\nOutput: -1\nExplanation: Even if you activate all the four taps you cannot water the whole garden.\n\nConstraints:\n\n- 1 <= n <= 10^4\n- ranges.length == n + 1\n- 0 <= ranges[i] <= 100\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

Jobs are dependent (i.e To work on the i^th job, you have to finish all the jobs j where 0 <= j < i).\n\nYou have to finish at least one task every day. The difficulty of a job schedule is the sum of difficulties of each day of the d days. The difficulty of a day is the maximum difficulty of a job done on that day.\n\nYou are given an integer array jobDifficulty and an integer d. The difficulty of the i^th job is jobDifficulty[i].\n\nReturn the minimum difficulty of a job schedule. If you cannot find a schedule for the jobs return -1.\n\nExample 1:\n\nInput: jobDifficulty = [6,5,4,3,2,1], d = 2\nOutput: 7\nExplanation: First day you can finish the first 5 jobs, total difficulty

+{"question_id": 1340, "task_id": "jump-game-v", "difficulty": "Hard", "problem_description": "Given an array of integers arr and an integer d. In one step you can jump from index i to index:\n\n- i + x where: i + x < arr.length and 0 < x <= d.\n- i - x where: i - x >= 0 and 0 < x <= d.\n\nIn addition, you can only jump from index i to index j if arr[i] > arr[j] and arr[i] > arr[k] for all indices k between i and j (More formally min(i, j) < k < max(i, j)).\n\nYou can choose any index of the array and start jumping. Return the maximum number of indices you can visit.\n\nNotice that you can not jump outside of the array at any time.\n\nExample 1:\n\nInput: arr = [6,4,14,6,8,13,9,7,10,6,12], d = 2\nOutput: 4\nExplanation: You can start at index 10. You can jump 10 --> 8 --> 6 --> 7 as shown.\nNote that if you start at index 6 you can only jump to index 7. You cannot jump to index 5 because 13 > 9. You cannot jump to index 4 because index 5 is between index 4 and 6 and 13 > 9.\nSimilarly You cannot jump from index 3 to index 2 or index 1.\n\nExample 2:\n\nInput: arr = [3,3,3,3,3], d = 3\nOutput: 1\nExplanation: You can start at any index. You always cannot jump to any index.\n\nExample 3:\n\nInput: arr = [7,6,5,4,3,2,1], d = 1\nOutput: 7\nExplanation: Start at index 0. You can visit all the indicies.\n\nConstraints:\n\n- 1 <= arr.length <= 1000\n- 1 <= arr[i] <= 10^5\n- 1 <= d <= arr.length\n", "canonical_tests": {"language": "python", "source": "def

If two or more teams tie in the first position, we consider the second position to resolve the conflict, if they tie again, we continue this process until the ties are resolved. If two or more teams are still tied after considering all positions, we rank them alphabetically based on their team letter.\n\nYou are given an array of strings votes which is the votes of all voters in the ranking systems. Sort all teams according to the ranking system described above.\n\nReturn a string of all teams sorted by the ranking system.\n\nExample 1:\n\nInput: votes = [\"ABC\",\"ACB\",\"ABC\",\"ACB\",\"ACB\"]\nOutput: \"ACB\"\nExplanation:\nTeam A was ranked first place by 5 voters. No other team was voted as first place, so team A is the first team.\nTeam B was ranked second by 2 voters and ranked third by 3 voters.\nTeam C was ranked second by 3 voters and ranked third by 2 voters.\nAs most of the voters ranked C second, team C is the second team, and team B is the third.\n\nExample 2:\n\nInput: votes = [\"WXYZ\",\"XYZW\"]\nOutput: \"XWYZ\"\nExplanation:\nX is the winner due to the tie-breaking rule. X has the same votes as W for the first position, but X has one vote in the second position, while W does not have any votes in the second position.\n\nExample 3:\n\nInput: votes =

A frog starts jumping from vertex 1. In one second, the frog jumps from its current vertex to another unvisited vertex if they are directly connected. The frog can not jump back to a visited vertex. In case the frog can jump to several vertices, it jumps randomly to one of them with the same probability. Otherwise, when the frog can not jump to any unvisited vertex, it jumps forever on the same vertex.\n\nThe edges of the undirected tree are given in the array edges, where edges[i] = [a_i, b_i] means that exists an edge connecting the vertices a_i and b_i.\n\nReturn the probability that after t seconds the frog is on the vertex target.

There are n engineers numbered from 1 to n. speed[i] and efficiency[i] represent the speed and efficiency of the i^th engineer respectively.\n\nChoose at most k different engineers out of the n engineers to form a team with the maximum performance.\n\nThe performance of a team is the sum of its engineers' speeds multiplied by the minimum efficiency among its engineers.\n\nReturn the maximum performance of this team. Since the answer can be a huge number, return it modulo 10^9 + 7.\n\nExample 1:\n\nInput: n = 6, speed = [2,10,3,1,5,8], efficiency = [5,4,3,9,7,2], k = 2\nOutput: 60\nExplanation:\nWe have the maximum performance of the team by selecting engineer 2 (with speed=10 and efficiency=4) and engineer 5 (with speed=5 and efficiency=7). That is, performance = (10 + 5) * min(4, 7) = 60.\n\nExample 2:\n\nInput: n = 6, speed = [2,10,3,1,5,8], efficiency = [5,4,3,9,7,2], k = 3\nOutput: 68\nExplanation:\nThis is the same example as the first but k = 3. We can select engineer 1, engineer 2 and engineer 5 to get the maximum performance of the team. That is, performance = (2 + 10 + 5) * min(5, 4, 7) = 68.\n\nExample 3:\n\nInput: n = 6, speed = [2,10,3,1,5,8], efficiency = [5,4,3,9,7,2], k = 4\nOutput: 72\n\nConstraints:\n\n- 1 <= k <= n <=

Each row has 10 seats, numbered from 1 to 10.\n\nYou are given a 2D integer array reservedSeats, where reservedSeats[i] = [row_i, seat_i] means that seat seat_i in row row_i is already reserved.\n\nA four-person group must be assigned to four seats in the same row. The group can be seated in one of the following seat blocks:\n\n- seats 2, 3, 4, 5\n- seats 4, 5, 6, 7\n- seats 6, 7, 8, 9\n\nA block can be used only if none of its seats are reserved. Each seat can be assigned to at most one group.\n\nReturn an integer denoting the maximum number of four-person groups that can be assigned.\n\nExample 1:\n\nInput: n = 3, reservedSeats = [[1,2],[1,3],[1,8],[2,6],[3,1],[3,10]]\nOutput: 4\nExplanation: The figure above shows an optimal allocation of four groups. Seats marked in blue are already reserved, and each set of four contiguous seats marked in orange is assigned to one group.\n\nExample 2:\n\nInput: n = 2, reservedSeats = [[2,1],[1,8],[2,6]]\nOutput: 2\n\nExample 3:\n\nInput: n = 4, reservedSeats = [[4,3],[1,4],[4,6],[1,7]]\nOutput: 4\n\nConstraints:\n\n- 1 <= n <= 10^9\n- 1 <= reservedSeats.length <= min(10 * n, 10^4)\n- reservedSeats[i] == [row_i, seat_i]\n- 1 <= row_i <= n\n- 1 <= seat_i <= 10\n- All reservedSeats[i] are distinct.\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(n =

The task is to sort all integers in the interval [lo, hi] by the power value in ascending order, if two or more integers have the same power value sort them by ascending order.\n\nReturn the k^th integer in the range [lo, hi] sorted by the power value.\n\nNotice that for any integer x (lo <= x <= hi) it is guaranteed that x will transform into 1 using these steps and that the power of x is will fit in a 32-bit signed integer.\n\nExample 1:\n\nInput: lo = 12, hi = 15, k = 2\nOutput: 13\nExplanation: The power of 12 is 9 (12 --> 6 --> 3 --> 10 --> 5 --> 16 --> 8 --> 4 --> 2 --> 1)\nThe power of 13 is 9\nThe power of 14 is 17\nThe power of 15 is 17\nThe interval sorted by the power value [12,13,14,15]. For k = 2 answer is the second element which is 13.\nNotice that 12 and 13 have the same power value and we sorted them in ascending order. Same for 14 and 15.\n\nExample 2:\n\nInput: lo = 7, hi = 11, k = 4\nOutput: 7\nExplanation: The power array corresponding to the interval [7, 8, 9, 10, 11] is [16, 3, 19, 6, 14].\nThe interval sorted by power is [8, 10, 11, 7, 9].\nThe fourth number in the sorted array is 7.\n\nConstraints:\n\n- 1 <= lo <= hi <= 1000\n- 1 <= k <= hi - lo + 1\n", "canonical_tests": {"language": "python", "source":

The street of grid[i][j] can be:\n\n- 1 which means a street connecting the left cell and the right cell.\n- 2 which means a street connecting the upper cell and the lower cell.\n- 3 which means a street connecting the left cell and the lower cell.\n- 4 which means a street connecting the right cell and the lower cell.\n- 5 which means a street connecting the left cell and the upper cell.\n- 6 which means a street connecting the right cell and the upper cell.\n\nYou will initially start at the street of the upper-left cell (0, 0). A valid path in the grid is a path that starts from the upper left cell (0, 0) and ends at the bottom-right cell (m - 1, n - 1). The path should only follow the streets.\n\nNotice that you are not allowed to change any street.\n\nReturn true if there is a valid path in the grid or false otherwise.\n\nExample 1:\n\nInput: grid = [[2,4,3],[6,5,2]]\nOutput: true\nExplanation: As shown you can start at cell (0, 0) and visit all the cells of the grid to reach (m - 1, n - 1).\n\nExample 2:\n\nInput: grid = [[1,2,1],[1,2,1]]\nOutput: false\nExplanation: As shown you the street at cell (0, 0) is not connected with any street of any other cell and you will get stuck at cell (0, 0)\n\nExample 3:\n\nInput: grid = [[1,1,2]]\nOutput: false\nExplanation: You will get stuck at cell (0, 1) and you cannot reach cell (0, 2).\n\nConstraints:\n\n- m == grid.length\n- n == grid[i].length\n- 1 <= m, n <= 300\n- 1

A subsequence of an array can be obtained by erasing some (possibly zero) elements from the array.\n\nNote that the solution with the given constraints is guaranteed to be unique. Also return the answer sorted in non-increasing order.\n\nExample 1:\n\nInput: nums = [4,3,10,9,8]\nOutput: [10,9]\nExplanation: The subsequences [10,9] and [10,8] are minimal such that the sum of their elements is strictly greater than the sum of elements not included. However, the subsequence [10,9] has the maximum total sum of its elements.\n\nExample 2:\n\nInput: nums = [4,4,7,6,7]\nOutput: [7,7,6]\nExplanation: The subsequence [7,7] has the sum of its elements equal to 14 which is not strictly greater than the sum of elements not included (14 = 4 + 4 + 6).

+{"question_id": 1406, "task_id": "stone-game-iii", "difficulty": "Hard", "problem_description": "Alice and Bob continue their games with piles of stones. There are several stones arranged in a row, and each stone has an associated value which is an integer given in the array stoneValue.\n\nAlice and Bob take turns, with Alice starting first. On each player's turn, that player can take 1, 2, or 3 stones from the first remaining stones in the row.\n\nThe score of each player is the sum of the values of the stones taken. The score of each player is 0 initially.\n\nThe objective of the game is to end with the highest score, and the winner is the player with the highest score and there could be a tie. The game continues until all the stones have been taken.\n\nAssume Alice and Bob play optimally.\n\nReturn \"Alice\" if Alice will win, \"Bob\" if Bob will win, or \"Tie\" if they will end the game with the same score.\n\nExample 1:\n\nInput: stoneValue = [1,2,3,7]\nOutput: \"Bob\"\nExplanation: Alice will always lose. Her best move will be to take three piles and the score become 6. Now the score of Bob is 7 and Bob wins.\n\nExample 2:\n\nInput: stoneValue = [1,2,3,-9]\nOutput: \"Alice\"\nExplanation: Alice must choose all the three piles at the first move to win and leave Bob with negative score.\nIf Alice chooses one pile her score will be 1 and the next move Bob's score becomes 5. In the next move, Alice will take the pile with value = -9 and lose.\nIf Alice chooses two piles her score will be 3 and the next move Bob's score becomes 3. In the next move, Alice will take the pile with value = -9 and also lose.\nRemember that both play optimally so here Alice will choose the scenario that makes her win.\n\nExample 3:\n\nInput: stoneValue = [1,2,3,6]\nOutput: \"Tie\"\nExplanation: Alice cannot win this game.

+{"question_id": 1409, "task_id": "queries-on-a-permutation-with-key", "difficulty": "Medium", "problem_description": "Given the array queries of positive integers between 1 and m, you have to process all queries[i] (from i=0 to i=queries.length-1) according to the following rules:\n\n- In the beginning, you have the permutation P=[1,2,3,...,m].\n- For the current i, find the position of queries[i] in the permutation P (indexing from 0) and then move this at the beginning of the permutation P. Notice that the position of queries[i] in P is the result for queries[i].\n\nReturn an array containing the result for the given queries.\n\nExample 1:\n\nInput: queries = [3,1,2,1], m = 5\nOutput: [2,1,2,1]\nExplanation: The queries are processed as follow:\nFor i=0: queries[i]=3, P=[1,2,3,4,5], position of 3 in P is 2, then we move 3 to the beginning of P resulting in P=[3,1,2,4,5].\nFor i=1: queries[i]=1, P=[3,1,2,4,5], position of 1 in P is 1, then we move 1 to the beginning of P resulting in P=[1,3,2,4,5].\nFor i=2: queries[i]=2, P=[1,3,2,4,5], position of 2 in P is 2, then we move 2 to the beginning of P resulting in P=[2,1,3,4,5].\nFor i=3: queries[i]=1, P=[2,1,3,4,5], position of 1 in P is 1, then we move 1 to the beginning of P resulting in P=[1,2,3,4,5].\nTherefore, the array containing the result is [2,1,2,1].\n\nExample 2:\n\nInput: queries = [4,1,2,2], m = 4\nOutput: [3,1,2,0]\n\nExample 3:\n\nInput: queries = [7,5,5,8,3], m = 8\nOutput: [6,5,0,7,5]\n\nConstraints:\n\n-

The points are given in the integer array cardPoints.\n\nIn one step, you can take one card from the beginning or from the end of the row. You have to take exactly k cards.\n\nYour score is the sum of the points of the cards you have taken.\n\nGiven the integer array cardPoints and the integer k, return the maximum score you can obtain.\n\nExample 1:\n\nInput: cardPoints = [1,2,3,4,5,6,1], k = 3\nOutput: 12\nExplanation: After the first step, your score will always be 1. However, choosing the rightmost card first will maximize your total score. The optimal strategy is to take the three cards on the right, giving a final score of 1 + 6 + 5 = 12.\n\nExample 2:\n\nInput: cardPoints = [2,2,2], k = 2\nOutput: 4\nExplanation: Regardless of which two cards you take, your score will always be 4.\n\nExample 3:\n\nInput: cardPoints = [9,7,7,9,7,7,9], k = 7\nOutput: 55\nExplanation: You have to take all the cards. Your score is the sum of points of all cards.\n\nConstraints:\n\n- 1 <= cardPoints.length <= 10^5\n- 1 <= cardPoints[i] <= 10^4\n- 1 <= k <= cardPoints.length\n", "canonical_tests": {"language":

+{"question_id": 1431, "task_id": "kids-with-the-greatest-number-of-candies", "difficulty": "Easy", "problem_description": "There are n kids with candies. You are given an integer array candies, where each candies[i] represents the number of candies the i^th kid has, and an integer extraCandies, denoting the number of extra candies that you have.\n\nReturn a boolean array result of length n, where result[i] is true if, after giving the i^th kid all the extraCandies, they will have the greatest number of candies among all the kids, or false otherwise.\n\nNote that multiple kids can have the greatest number of candies.\n\nExample 1:\n\nInput: candies = [2,3,5,1,3], extraCandies = 3\nOutput: [true,true,true,false,true]\nExplanation: If you give all extraCandies to:\n- Kid 1, they will have 2 + 3 = 5 candies, which is the greatest among the kids.\n- Kid 2, they will have 3 + 3 = 6 candies, which is the greatest among the kids.\n- Kid 3, they will have 5 + 3 = 8 candies, which is the greatest among the kids.\n- Kid 4, they will have 1 + 3 = 4 candies, which is not the greatest among the kids.\n- Kid 5, they will have 3 + 3 = 6 candies, which is the greatest among the kids.\n\nExample 2:\n\nInput: candies = [4,2,1,1,2], extraCandies = 1\nOutput: [true,false,false,false,false]\nExplanation: There is only 1 extra candy.\nKid 1 will always have the greatest number of candies, even if a different kid is given the extra candy.\n\nExample 3:\n\nInput: candies = [12,1,12], extraCandies = 10\nOutput: [true,false,true]\n\nConstraints:\n\n- n == candies.length\n- 2 <= n <= 100\n- 1 <= candies[i] <= 100\n- 1 <= extraCandies <= 50\n", "canonical_tests": {"language": "python", "source": "def

You should follow the following rules:\n\n- If the stream of the integers is not empty, pick the next integer from the stream and push it to the top of the stack.\n- If the stack is not empty, pop the integer at the top of the stack.\n- If, at any moment, the elements in the stack (from the bottom to the top) are equal to target, do not read new integers from the stream and do not do more operations on the stack.\n\nReturn the stack operations needed to build target following the mentioned rules. If there are multiple valid answers, return any of them.\n\nExample 1:\n\nInput: target = [1,3], n = 3\nOutput: [\"Push\",\"Push\",\"Pop\",\"Push\"]\nExplanation: Initially the stack s is empty. The last element is the top of the stack.\nRead 1 from the stream and push it to the stack. s = [1].\nRead 2 from the stream and push it to the stack. s = [1,2].\nPop the integer on the top of the stack. s = [1].\nRead 3 from the stream and push it to the stack. s = [1,3].\n\nExample 2:\n\nInput: target = [1,2,3], n = 3\nOutput: [\"Push\",\"Push\",\"Push\"]\nExplanation: Initially the stack s is empty. The last element is the top of the stack.\nRead 1 from the stream and push it to the stack. s = [1].\nRead 2 from the stream and push it to the stack. s = [1,2].\nRead 3 from the stream and push it to the stack. s = [1,2,3].\n\nExample 3:\n\nInput: target = [1,2], n = 4\nOutput: [\"Push\",\"Push\"]\nExplanation: Initially the stack s is empty. The last element is the top of the stack.\nRead 1 from the stream and push it to the stack. s = [1].\nRead 2 from the stream and push it to the stack. s = [1,2].\nSince the stack (from the bottom to the top) is equal to target, we stop the stack operations.\nThe answers that read integer 3 from the stream are not accepted.\n\nConstraints:\n\n- 1 <= target.length <= 100\n- 1 <= n <= 100\n- 1 <=

+{"question_id": 1449, "task_id": "form-largest-integer-with-digits-that-add-up-to-target", "difficulty": "Hard", "problem_description": "Given an array of integers cost and an integer target, return the maximum integer you can paint under the following rules:\n\n- The cost of painting a digit (i + 1) is given by cost[i] (0-indexed).\n- The total cost used must be equal to target.\n- The integer does not have 0 digits.\n\nSince the answer may be very large, return it as a string. If there is no way to paint any integer given the condition, return \"0\".\n\nExample 1:\n\nInput: cost = [4,3,2,5,6,7,2,5,5], target = 9\nOutput: \"7772\"\nExplanation: The cost to paint the digit '7' is 2, and the digit '2' is 3. Then cost(\"7772\") = 2*3+ 3*1 = 9.

Then cost(\"85\") = 7 + 5 = 12.\n\nExample 3:\n\nInput: cost = [2,4,6,2,4,6,4,4,4], target = 5\nOutput: \"0\"\nExplanation: It is impossible to paint any integer with total cost equal to

In one step, you can select any non-empty subarray of arr and reverse it. You are allowed to make any number of steps.\n\nReturn true if you can make arr equal to target or false otherwise.\n\nExample 1:\n\nInput: target = [1,2,3,4], arr = [2,4,1,3]\nOutput: true\nExplanation: You can follow the next steps to convert arr to target:\n1- Reverse subarray [2,4,1], arr becomes [1,4,2,3]\n2- Reverse subarray [4,2], arr becomes [1,2,4,3]\n3- Reverse subarray [4,3], arr becomes [1,2,3,4]\nThere are multiple ways to convert arr to target, this is not the only way to do so.\n\nExample 2:\n\nInput: target = [7], arr = [7]\nOutput: true\nExplanation: arr is equal to target without any reverses.\n\nExample 3:\n\nInput: target = [3,7,9], arr = [3,7,11]\nOutput: false\nExplanation: arr does not have value 9 and it can never be converted to target.\n\nConstraints:\n\n- target.length == arr.length\n- 1 <= target.length <= 1000\n- 1 <= target[i] <= 1000\n- 1 <= arr[i] <= 1000\n", "canonical_tests": {"language": "python", "source": "def

+{"question_id": 1462, "task_id": "course-schedule-iv", "difficulty": "Medium", "problem_description": "There are a total of numCourses courses you have to take, labeled from 0 to numCourses - 1. You are given an array prerequisites where prerequisites[i] = [a_i, b_i] indicates that you must take course a_i first if you want to take course b_i.\n\n- For example, the pair [0, 1] indicates that you have to take course 0 before you can take course 1.\n\nPrerequisites can also be indirect. If course a is a prerequisite of course b, and course b is a prerequisite of course c, then course a is a prerequisite of course c.\n\nYou are also given an array queries where queries[j] = [u_j, v_j]. For the j^th query, you should answer whether course u_j is a prerequisite of course v_j or not.\n\nReturn a boolean array answer, where answer[j] is the answer to the j^th query.\n\nExample 1:\n\nInput: numCourses = 2, prerequisites = [[1,0]], queries = [[0,1],[1,0]]\nOutput: [false,true]\nExplanation: The pair [1, 0] indicates that you have to take course 1 before you can take course 0.\nCourse 0 is not a prerequisite of course 1, but the opposite is true.\n\nExample 2:\n\nInput: numCourses = 2, prerequisites = [], queries = [[1,0],[0,1]]\nOutput: [false,false]\nExplanation: There are no prerequisites, and each course is independent.\n\nExample 3:\n\nInput: numCourses = 3, prerequisites = [[1,2],[1,0],[2,0]], queries = [[1,0],[1,2]]\nOutput: [true,true]\n\nConstraints:\n\n- 2 <= numCourses <= 100\n- 0 <= prerequisites.length <= (numCourses * (numCourses - 1) / 2)\n- prerequisites[i].length == 2\n- 0 <= a_i, b_i <= numCourses - 1\n- a_i != b_i\n- All the pairs [a_i, b_i] are unique.\n- The prerequisites graph has no cycles.\n- 1 <= queries.length <= 10^4\n- 0 <= u_i, v_i <= numCourses - 1\n- u_i != v_i\n", "canonical_tests": {"language": "python", "source": "def

You will be given an integer array balls of size k where balls[i] is the number of balls of color i.\n\nAll the balls will be shuffled uniformly at random, then we will distribute the first n balls to the first box and the remaining n balls to the other box (Please read the explanation of the second example carefully).\n\nPlease note that the two boxes are considered different. For example, if we have two balls of colors a and b, and two boxes [] and (), then the distribution [a] (b) is considered different than the distribution [b] (a) (Please read the explanation of the first example carefully).\n\nReturn the probability that the two boxes have the same number of distinct balls. Answers within 10^-5 of the actual value will be accepted as correct.\n\nExample 1:\n\nInput: balls = [1,1]\nOutput: 1.00000\nExplanation: Only 2 ways to divide the balls equally:\n- A ball of color 1 to box 1 and a ball of color 2 to box 2\n- A ball of color 2 to box 1 and a ball of color 1 to box 2\nIn both ways, the number of distinct colors in each box is equal. The probability is 2/2 = 1\n\nExample 2:\n\nInput: balls = [2,1,1]\nOutput: 0.66667\nExplanation: We have the set of balls [1, 1, 2, 3]\nThis set of balls will be shuffled randomly and we may have one of the 12 distinct shuffles with equal probability (i.e. 1/12):\n[1,1 / 2,3], [1,1 / 3,2], [1,2 / 1,3], [1,2 / 3,1], [1,3 / 1,2], [1,3 / 2,1], [2,1 / 1,3], [2,1 / 3,1], [2,3 / 1,1], [3,1 / 1,2], [3,1 / 2,1], [3,2 / 1,1]\nAfter that, we add the first two balls to the first box and the second two balls to the second box.\nWe can see that 8 of these 12 possible random distributions have the same number of distinct colors of balls in each box.\nProbability is 8/12 = 0.66667\n\nExample 3:\n\nInput: balls = [1,2,1,2]\nOutput: 0.60000\nExplanation: The set of balls is [1, 2, 2, 3, 4, 4]. It is hard to display all the 180 possible random shuffles of this set but it is easy to check that 108 of them will have the same number of distinct colors in each box.\nProbability = 108 / 180 =

Return the answer in any arbitrary order.\n\nThe centre is the middle value in an ordered integer list. More formally, if the length of the list is n, the centre is the element in position ((n - 1) / 2) in the sorted list (0-indexed).\n\n- For arr = [6, -3, 7, 2, 11], n = 5 and the centre is obtained by sorting the array arr = [-3, 2, 6, 7, 11] and the centre is arr[m] where m = ((5 - 1) / 2) = 2. The centre is 6.\n- For arr = [-7, 22, 17, 3], n = 4 and the centre is obtained by sorting the array arr = [-7, 3, 17, 22] and the centre is arr[m] where m = ((4 - 1) / 2) = 1. The centre is 3.\n\nExample 1:\n\nInput: arr = [1,2,3,4,5], k = 2\nOutput: [5,1]\nExplanation: Centre is 3, the elements of the array sorted by the strongest are [5,1,4,2,3]. The strongest 2 elements are [5, 1]. [1, 5] is also accepted answer.\nPlease note that although |5 - 3| == |1 - 3| but 5 is stronger than 1 because 5 > 1.\n\nExample 2:\n\nInput: arr = [1,1,3,5,5], k = 2\nOutput: [5,5]\nExplanation: Centre is 3, the elements of the array sorted by the strongest are [5,5,1,1,3]. The strongest 2 elements are [5, 5].\n\nExample 3:\n\nInput: arr = [6,7,11,7,6,8], k = 5\nOutput: [11,8,6,6,7]\nExplanation: Centre is 7, the elements of the array sorted by the strongest are [11,8,6,6,7,7].\nAny permutation of [11,8,6,6,7] is accepted.\n\nConstraints:\n\n- 1 <= arr.length <= 10^5\n- -10^5 <= arr[i] <= 10^5\n- 1 <= k <= arr.length\n", "canonical_tests": {"language":

If you buy the i^th item, then you will receive a discount equivalent to prices[j] where j is the minimum index such that j > i and prices[j] <= prices[i]. Otherwise, you will not receive any discount at all.\n\nReturn an integer array answer where answer[i] is the final price you will pay for the i^th item of the shop, considering the special discount.\n\nExample 1:\n\nInput: prices = [8,4,6,2,3]\nOutput: [4,2,4,2,3]\nExplanation:\nFor item 0 with price[0]=8 you will receive a discount equivalent to prices[1]=4, therefore, the final price you will pay is 8 - 4 = 4.\nFor item 1 with price[1]=4 you will receive a discount equivalent to prices[3]=2, therefore, the final price you will pay is 4 - 2 = 2.\nFor item 2 with price[2]=6 you will receive a discount equivalent to prices[3]=2, therefore, the final price you will pay is 6 - 2 = 4.\nFor items 3 and 4 you will not receive any discount at all.\n\nExample 2:\n\nInput: prices = [1,2,3,4,5]\nOutput: [1,2,3,4,5]\nExplanation: In this case, for all items, you will not receive any discount at all.\n\nExample 3:\n\nInput: prices = [10,1,1,6]\nOutput:

+{"question_id": 1487, "task_id": "making-file-names-unique", "difficulty": "Medium", "problem_description": "Given an array of strings names of size n. You will create n folders in your file system such that, at the i^th minute, you will create a folder with the name names[i].\n\nSince two files cannot have the same name, if you enter a folder name that was previously used, the system will have a suffix addition to its name in the form of (k), where, k is the smallest positive integer such that the obtained name remains unique.\n\nReturn an array of strings of length n where ans[i] is the actual name the system will assign to the i^th folder when you create it.\n\nExample 1:\n\nInput: names = [\"pes\",\"fifa\",\"gta\",\"pes(2019)\"]\nOutput: [\"pes\",\"fifa\",\"gta\",\"pes(2019)\"]\nExplanation: Let's see how the file system creates folder names:\n\"pes\" --> not assigned before, remains \"pes\"\n\"fifa\" --> not assigned before, remains \"fifa\"\n\"gta\" --> not assigned before, remains \"gta\"\n\"pes(2019)\" --> not assigned before, remains \"pes(2019)\"\n\nExample 2:\n\nInput: names = [\"gta\",\"gta(1)\",\"gta\",\"avalon\"]\nOutput: [\"gta\",\"gta(1)\",\"gta(2)\",\"avalon\"]\nExplanation: Let's see how the file system creates folder names:\n\"gta\" --> not assigned before, remains \"gta\"\n\"gta(1)\" --> not assigned before, remains \"gta(1)\"\n\"gta\" --> the name is reserved, system adds (k), since \"gta(1)\" is also reserved, systems put k = 2. it becomes \"gta(2)\"\n\"avalon\" --> not assigned before, remains \"avalon\"\n\nExample 3:\n\nInput: names = [\"onepiece\",\"onepiece(1)\",\"onepiece(2)\",\"onepiece(3)\",\"onepiece\"]\nOutput: [\"onepiece\",\"onepiece(1)\",\"onepiece(2)\",\"onepiece(3)\",\"onepiece(4)\"]\nExplanation: When the last folder is created, the smallest positive valid k is 4, and it becomes \"onepiece(4)\".\n\nConstraints:\n\n- 1 <= names.length <= 5 * 10^4\n- 1 <= names[i].length <= 20\n- names[i] consists of lowercase English letters, digits, and/or round brackets.\n",

+{"question_id": 1488, "task_id": "avoid-flood-in-the-city", "difficulty": "Medium", "problem_description": "Your country has 10^9 lakes. Initially, all the lakes are empty, but when it rains over the n^th lake, the n^th lake becomes full of water. If it rains over a lake that is full of water, there will be a flood. Your goal is to avoid floods in any lake.\n\nGiven an integer array rains where:\n\n- rains[i] > 0 means there will be rains over the rains[i] lake.\n- rains[i] == 0 means there are no rains this day and you must choose one lake this day and dry it.\n\nReturn an array ans where:\n\n- ans.length == rains.length\n- ans[i] == -1 if rains[i] > 0.\n- ans[i] is the lake you choose to dry in the ith day if rains[i] == 0.\n\nIf there are multiple valid answers return any of them. If it is impossible to avoid flood return an empty array.\n\nNotice that if you chose to dry a full lake, it becomes empty, but if you chose to dry an empty lake, nothing changes.\n\nExample 1:\n\nInput: rains = [1,2,3,4]\nOutput: [-1,-1,-1,-1]\nExplanation: After the first day full lakes are [1]\nAfter the second day full lakes are [1,2]\nAfter the third day full lakes are [1,2,3]\nAfter the fourth day full lakes are [1,2,3,4]\nThere's no day to dry any lake and there is no flood in any lake.\n\nExample 2:\n\nInput: rains = [1,2,0,0,2,1]\nOutput: [-1,-1,2,1,-1,-1]\nExplanation: After the first day full lakes are [1]\nAfter the second day full lakes are [1,2]\nAfter the third day, we dry lake 2. Full lakes are [1]\nAfter the fourth day, we dry lake 1. There is no full lakes.\nAfter the fifth day, full lakes are [2].\nAfter the sixth day, full lakes are [1,2].\nIt is easy that this scenario is flood-free. [-1,-1,1,2,-1,-1] is another acceptable scenario.\n\nExample 3:\n\nInput: rains = [1,2,0,1,2]\nOutput: []\nExplanation: After the second day, full lakes are [1,2]. We have to dry one lake in the third day.\nAfter that, it will rain over lakes [1,2]. It's easy to prove that no matter which lake you choose to dry in the 3rd day, the other one will flood.\n\nConstraints:\n\n- 1 <= rains.length <= 10^5\n- 0 <= rains[i] <= 10^9\n", "canonical_tests":

A minimum spanning tree (MST) is a subset of the graph's edges that connects all vertices without cycles and with the minimum possible total edge weight.\n\nFind all the critical and pseudo-critical edges in the given graph's minimum spanning tree (MST). An MST edge whose deletion from the graph would cause the MST weight to increase is called a critical edge. On the other hand, a pseudo-critical edge is that which can appear in some MSTs but not all.\n\nNote that you can return the indices of the edges in any order.\n\nExample 1:\n\nInput: n = 5, edges = [[0,1,1],[1,2,1],[2,3,2],[0,3,2],[0,4,3],[3,4,3],[1,4,6]]\nOutput: [[0,1],[2,3,4,5]]\nExplanation: The figure above describes the graph.\nThe following figure shows all the possible MSTs:\n\nNotice that the two edges 0 and 1 appear in all MSTs, therefore they are critical edges, so we return them in the first list of the output.\nThe edges 2, 3, 4, and 5 are only part of some MSTs, therefore they are considered pseudo-critical edges. We add them to the second list of the output.\n\nExample 2:\n\nInput: n = 4, edges = [[0,1,1],[1,2,1],[2,3,1],[0,3,1]]\nOutput: [[],[0,1,2,3]]\nExplanation: We can observe that since all 4 edges have equal weight, choosing any 3 edges from the given 4 will yield an MST. Therefore all 4 edges are pseudo-critical.\n\nConstraints:\n\n- 2 <= n <= 100\n- 1 <= edges.length <= min(200, n * (n - 1) / 2)\n- edges[i].length == 3\n- 0 <= a_i < b_i < n\n- 1 <= weight_i <=

Some ants are walking on the plank, each ant moves with a speed of 1 unit per second. Some of the ants move to the left, the other move to the right.\n\nWhen two ants moving in two different directions meet at some point, they change their directions and continue moving again. Assume changing directions does not take any additional time.\n\nWhen an ant reaches one end of the plank at a time t, it falls out of the plank immediately.\n\nGiven an integer n and two integer arrays left and right, the positions of the ants moving to the left and the right, return the moment when the last ant(s) fall out of the plank.\n\nExample 1:\n\nInput: n = 4, left = [4,3], right = [0,1]\nOutput: 4\nExplanation: In the image above:\n-The ant at index 0 is named A and going to the right.\n-The ant at index 1 is named B and going to the right.\n-The ant at index 3 is named C and going to the left.\n-The ant at index 4 is named D and going to the left.\nThe last moment when an ant was on the plank is t = 4 seconds. After that, it falls immediately out of the plank.

The company knows the positions of all the customers in this city on a 2D-Map and wants to build the new center in a position such that the sum of the euclidean distances to all customers is minimum.\n\nGiven an array positions where positions[i] = [x_i, y_i] is the position of the ith customer on the map, return the minimum sum of the euclidean distances to all customers.\n\nIn other words, you need to choose the position of the service center [x_centre, y_centre] such that the following formula is minimized:\n\nAnswers within 10^-5 of the actual value will be accepted.\n\nExample 1:\n\nInput: positions = [[0,1],[1,0],[1,2],[2,1]]\nOutput: 4.00000\nExplanation: As shown, you can see that choosing [x_centre, y_centre] = [1, 1] will make the distance to each customer = 1, the sum of all distances is 4 which is the minimum possible we can achieve.\n\nExample 2:\n\nInput: positions = [[1,1],[3,3]]\nOutput: 2.82843\nExplanation: The minimum possible sum of distances = sqrt(2) + sqrt(2) = 2.82843\n\nConstraints:\n\n- 1 <= positions.length <= 50\n- positions[i].length == 2\n- 0 <= x_i, y_i <= 100\n", "canonical_tests": {"language": "python", "source": "def

+{"question_id": 1520, "task_id": "maximum-number-of-non-overlapping-substrings", "difficulty": "Hard", "problem_description": "Given a string s of lowercase letters, you need to find the maximum number of non-empty substrings of s that meet the following conditions:\n\n1. The substrings do not overlap, that is for any two substrings s[i..j] and s[x..y], either j < x or i > y is true.\n2. A substring that contains a certain character c must also contain all occurrences of c.\n\nFind the maximum number of substrings that meet the above conditions. If there are multiple solutions with the same number of substrings, return the one with minimum total length. It can be shown that there exists a unique solution of minimum total length.\n\nNotice that you can return the substrings in any order.\n\nExample 1:\n\nInput: s = \"adefaddaccc\"\nOutput: [\"e\",\"f\",\"ccc\"]\nExplanation: The following are all the possible substrings that meet the conditions:\n[\n \"adefaddaccc\"\n \"adefadda\",\n \"ef\",\n \"e\",\n \"f\",\n \"ccc\",\n]\nIf we choose the first string, we cannot choose anything else and we'd get only 1. If we choose \"adefadda\", we are left with \"ccc\" which is the only one that doesn't overlap, thus obtaining 2 substrings. Notice also, that it's not optimal to choose \"ef\" since it can be split into two. Therefore, the optimal way is to choose [\"e\",\"f\",\"ccc\"] which gives us 3 substrings. No other solution of the same number of substrings exist.\n\nExample 2:\n\nInput: s = \"abbaccd\"\nOutput: [\"d\",\"bb\",\"cc\"]\nExplanation: Notice that while the set of substrings [\"d\",\"abba\",\"cc\"] also has length 3, it's considered incorrect since it has larger total length.\n\nConstraints:\n\n- 1 <= s.length <= 10^5\n- s contains only lowercase English letters.\n",

Flip means changing '0' to '1' and '1' to '0'.\n\nReturn the minimum number of operations needed to make s equal to target.\n\nExample 1:\n\nInput: target = \"10111\"\nOutput: 3\nExplanation: Initially, s = \"00000\".\nChoose index i = 2: \"00000\" -> \"00111\"\nChoose index i = 0: \"00111\" -> \"11000\"\nChoose index i = 1: \"11000\" -> \"10111\"\nWe need at least 3 flip operations to form target.\n\nExample 2:\n\nInput: target = \"101\"\nOutput: 3\nExplanation: Initially, s = \"000\".\nChoose index i = 0: \"000\" -> \"111\"\nChoose index i = 1: \"111\" -> \"100\"\nChoose index i = 2: \"100\" -> \"101\"\nWe need at least 3 flip operations to form target.\n\nExample 3:\n\nInput: target = \"00000\"\nOutput: 0\nExplanation: We do not need any operations since the initial s already equals target.\n\nConstraints:\n\n- n == target.length\n- 1 <= n <= 10^5\n- target[i] is either '0' or '1'.\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert

+{"question_id": 1531, "task_id": "string-compression-ii", "difficulty": "Hard", "problem_description": "Run-length encoding is a string compression method that works by replacing consecutive identical characters (repeated 2 or more times) with the concatenation of the character and the number marking the count of the characters (length of the run). For example, to compress the string \"aabccc\" we replace \"aa\" by \"a2\" and replace \"ccc\" by \"c3\". Thus the compressed string becomes \"a2bc3\".\n\nNotice that in this problem, we are not adding '1' after single characters.\n\nGiven a string s and an integer k. You need to delete at most k characters from s such that the run-length encoded version of s has minimum length.\n\nFind the minimum length of the run-length encoded version of s after deleting at most k characters.\n\nExample 1:\n\nInput: s = \"aaabcccd\", k = 2\nOutput: 4\nExplanation: Compressing s without deleting anything will give us \"a3bc3d\" of length 6. Deleting any of the characters 'a' or 'c' would at most decrease the length of the compressed string to 5, for instance delete 2 'a' then we will have s = \"abcccd\" which compressed is abc3d. Therefore, the optimal way is to delete 'b' and 'd', then the compressed version of s will be \"a3c3\" of length 4.\n\nExample 2:\n\nInput: s = \"aabbaa\", k = 2\nOutput: 2\nExplanation: If we delete both 'b' characters, the resulting compressed string would be \"a4\" of length 2.\n\nExample 3:\n\nInput: s = \"aaaaaaaaaaa\", k = 0\nOutput: 3\nExplanation: Since k is zero, we cannot delete anything. The compressed string is \"a11\" of length 3.\n\nConstraints:\n\n- 1 <= s.length <= 100\n- 0 <= k <= s.length\n- s contains only lowercase English letters.\n", "canonical_tests": {"language":

+{"question_id": 1535, "task_id": "find-the-winner-of-an-array-game", "difficulty": "Medium", "problem_description": "Given an integer array arr of distinct integers and an integer k.\n\nA game will be played between the first two elements of the array (i.e. arr[0] and arr[1]). In each round of the game, we compare arr[0] with arr[1], the larger integer wins and remains at position 0, and the smaller integer moves to the end of the array. The game ends when an integer wins k consecutive rounds.\n\nReturn the integer which will win the game.\n\nIt is guaranteed that there will be a winner of the game.\n\nExample 1:\n\nInput: arr = [2,1,3,5,4,6,7], k = 2\nOutput: 5\nExplanation: Let's see the rounds of the game:\nRound | arr | winner | win_count\n 1 | [2,1,3,5,4,6,7] | 2 | 1\n 2 | [2,3,5,4,6,7,1] | 3 | 1\n 3 | [3,5,4,6,7,1,2] | 5 | 1\n 4 | [5,4,6,7,1,2,3] | 5 | 2\nSo we can see that 4 rounds will be played and 5 is the winner because it wins 2 consecutive games.\n\nExample 2:\n\nInput: arr = [3,2,1], k = 10\nOutput: 3\nExplanation: 3 will win the first 10 rounds consecutively.\n\nConstraints:\n\n- 2 <= arr.length <= 10^5\n- 1 <= arr[i] <= 10^6\n- arr contains distinct integers.\n- 1 <= k <= 10^9\n",

(Only one repeated value is considered in the valid path).\n\nThe score is defined as the sum of unique values in a valid path.\n\nReturn the maximum score you can obtain of all possible valid paths. Since the answer may be too large, return it modulo 10^9 + 7.\n\nExample 1:\n\nInput: nums1 = [2,4,5,8,10], nums2 = [4,6,8,9]\nOutput: 30\nExplanation: Valid paths:\n[2,4,5,8,10], [2,4,5,8,9],

2:\n\nInput: nums1 = [1,3,5,7,9], nums2 = [3,5,100]\nOutput: 109\nExplanation: Maximum sum is obtained with the path [1,3,5,100].\n\nExample 3:\n\nInput: nums1 = [1,2,3,4,5], nums2 = [6,7,8,9,10]\nOutput: 40\nExplanation: There are no common elements between nums1 and nums2.\nMaximum sum is obtained with the path [6,7,8,9,10].\n\nConstraints:\n\n- 1 <= nums1.length, nums2.length

+{"question_id": 1540, "task_id": "can-convert-string-in-k-moves", "difficulty": "Medium", "problem_description": "Given two strings s and t, your goal is to convert s into t in k moves or less.\n\nDuring the i^th (1 <= i <= k) move you can:\n\n- Choose any index j (1-indexed) from s, such that 1 <= j <= s.length and j has not been chosen in any previous move, and shift the character at that index i times.\n- Do nothing.\n\nShifting a character means replacing it by the next letter in the alphabet (wrapping around so that 'z' becomes 'a'). Shifting a character by i means applying the shift operations i times.\n\nRemember that any index j can be picked at most once.\n\nReturn true if it's possible to convert s into t in no more than k moves, otherwise return false.\n\nExample 1:\n\nInput: s = \"input\", t = \"ouput\", k = 9\nOutput: true\nExplanation: In the 6th move, we shift 'i' 6 times to get 'o'. And in the 7th move we shift 'n' to get 'u'.\n\nExample 2:\n\nInput: s = \"abc\", t = \"bcd\", k = 10\nOutput: false\nExplanation: We need to shift each character in s one time to convert it into t. We can shift 'a' to 'b' during the 1st move. However, there is no way to shift the other characters in the remaining moves to obtain t from s.\n\nExample 3:\n\nInput: s = \"aab\", t = \"bbb\", k = 27\nOutput: true\nExplanation: In the 1st move, we shift the first 'a' 1 time to get 'b'. In the 27th move, we shift the second 'a' 27 times to get 'b'.\n\nConstraints:\n\n- 1 <= s.length, t.length <= 10^5\n- 0 <= k <= 10^9\n- s, t contain only lowercase English letters.\n",

+{"question_id": 1547, "task_id": "minimum-cost-to-cut-a-stick", "difficulty": "Hard", "problem_description": "Given a wooden stick of length n units. The stick is labelled from 0 to n. For example, a stick of length 6 is labelled as follows:\n\nGiven an integer array cuts where cuts[i] denotes a position you should perform a cut at.\n\nYou should perform the cuts in order, you can change the order of the cuts as you wish.\n\nThe cost of one cut is the length of the stick to be cut, the total cost is the sum of costs of all cuts. When you cut a stick, it will be split into two smaller sticks (i.e. the sum of their lengths is the length of the stick before the cut). Please refer to the first example for a better explanation.\n\nReturn the minimum total cost of the cuts.\n\nExample 1:\n\nInput: n = 7, cuts = [1,3,4,5]\nOutput: 16\nExplanation: Using cuts order = [1, 3, 4, 5] as in the input leads to the following scenario:\n\nThe first cut is done to a rod of length 7 so the cost is 7. The second cut is done to a rod of length 6 (i.e. the second part of the first cut), the third is done to a rod of length 4 and the last cut is to a rod of length 3. The total cost is 7 + 6 + 4 + 3 = 20.\nRearranging the cuts to be [3, 5, 1, 4] for example will lead to a scenario with total cost = 16 (as shown in the example photo 7 + 4 + 3 + 2 = 16).\n\nExample 2:\n\nInput: n = 9, cuts = [5,6,1,4,2]\nOutput: 22\nExplanation: If you try the given cuts ordering the cost will be 25.\nThere are much ordering with total cost <= 25, for example, the order [4, 6, 5, 2, 1] has total cost = 22 which is the minimum possible.\n\nConstraints:\n\n- 2 <= n <= 10^6\n- 1 <= cuts.length <= min(n - 1, 100)\n- 1 <= cuts[i] <= n - 1\n- All the integers in cuts array are

From a given cell, you can move to one of the cells adjacent to it - in one of the four directions (up, down, left, or right), if it has the same value of the current cell.\n\nAlso, you cannot move to the cell that you visited in your last move. For example, the cycle (1, 1) -> (1, 2) -> (1, 1) is invalid because from (1, 2) we visited (1, 1) which was the last visited cell.\n\nReturn true if any cycle of the same value exists in grid, otherwise, return false.\n\nExample 1:\n\nInput: grid = [[\"a\",\"a\",\"a\",\"a\"],[\"a\",\"b\",\"b\",\"a\"],[\"a\",\"b\",\"b\",\"a\"],[\"a\",\"a\",\"a\",\"a\"]]\nOutput: true\nExplanation: There are

We have a circular track which consists of n sectors labeled from 1 to n. A marathon will be held on this track, the marathon consists of m rounds. The i^th round starts at sector rounds[i - 1] and ends at sector rounds[i]. For example, round 1 starts at sector rounds[0] and ends at sector rounds[1]\n\nReturn an array of the most visited sectors sorted in ascending order.\n\nNotice that you circulate the track in ascending order of sector numbers in the counter-clockwise direction (See the first example).\n\nExample 1:\n\nInput: n = 4, rounds = [1,3,1,2]\nOutput: [1,2]\nExplanation: The marathon starts at sector 1. The order of the visited sectors is as follows:\n1 --> 2 --> 3 (end of round 1) --> 4 --> 1 (end of round 2) --> 2 (end of round 3 and the marathon)\nWe can see that both sectors 1 and 2 are visited twice and they are the most visited sectors.

+{"question_id": 1563, "task_id": "stone-game-v", "difficulty": "Hard", "problem_description": "There are several stones arranged in a row, and each stone has an associated value which is an integer given in the array stoneValue.\n\nIn each round of the game, Alice divides the row into two non-empty rows (i.e. left row and right row), then Bob calculates the value of each row which is the sum of the values of all the stones in this row. Bob throws away the row which has the maximum value, and Alice's score increases by the value of the remaining row. If the value of the two rows are equal, Bob lets Alice decide which row will be thrown away. The next round starts with the remaining row.\n\nThe game ends when there is only one stone remaining. Alice's score is initially zero.\n\nReturn the maximum score that Alice can obtain.\n\nExample 1:\n\nInput: stoneValue = [6,2,3,4,5,5]\nOutput: 18\nExplanation: In the first round, Alice divides the row to [6,2,3], [4,5,5]. The left row has the value 11 and the right row has value 14. Bob throws away the right row and Alice's score is now 11.\nIn the second round Alice divides the row to [6], [2,3]. This time Bob throws away the left row and Alice's score becomes 16 (11 + 5).\nThe last round Alice has only one choice to divide the row which is [2], [3]. Bob throws away the right row and Alice's score is now 18 (16 + 2). The game ends because only one stone is remaining in the row.\n\nExample 2:\n\nInput: stoneValue = [7,7,7,7,7,7,7]\nOutput: 28\n\nExample 3:\n\nInput: stoneValue = [4]\nOutput: 0\n\nConstraints:\n\n-

You are also given integers start, finish and fuel representing the starting city, ending city, and the initial amount of fuel you have, respectively.\n\nAt each step, if you are at city i, you can pick any city j such that j != i and 0 <= j < locations.length and move to city j. Moving from city i to city j reduces the amount of fuel you have by |locations[i] - locations[j]|. Please notice that |x| denotes the absolute value of x.\n\nNotice that fuel cannot become negative at any point in time, and that you are allowed to visit any city more than once (including start and finish).\n\nReturn the count of all possible routes from start to finish. Since the answer may be too large, return it modulo 10^9 + 7.\n\nExample 1:\n\nInput: locations = [2,3,6,8,4], start = 1, finish = 3, fuel = 5\nOutput: 4\nExplanation: The following are all possible routes, each uses 5 units of fuel:\n1 -> 3\n1 -> 2 -> 3\n1 -> 4 -> 3\n1 -> 4 -> 2 -> 3\n\nExample 2:\n\nInput: locations = [4,3,1], start = 1, finish = 0, fuel = 6\nOutput: 5\nExplanation: The following are all possible routes:\n1 -> 0, used fuel = 1\n1 -> 2 -> 0, used fuel = 5\n1 -> 2 -> 1 -> 0, used fuel = 5\n1 -> 0 -> 1 -> 0, used fuel = 3\n1 -> 0 -> 1 -> 0 -> 1 -> 0, used fuel = 5\n\nExample 3:\n\nInput: locations = [5,2,1], start = 0, finish = 2, fuel = 3\nOutput: 0\nExplanation: It is impossible to get from 0 to 2 using only 3 units of fuel since the shortest route needs 4 units of fuel.\n\nConstraints:\n\n- 2 <= locations.length <= 100\n- 1 <= locations[i] <= 10^9\n- All integers in locations are distinct.\n- 0 <= start, finish < locations.length\n- 1 <= fuel <=

You are given a 0-indexed integer array neededTime where neededTime[i] is the time (in seconds) that Bob needs to remove the i^th balloon from the rope.\n\nReturn the minimum time Bob needs to make the rope colorful.\n\nExample 1:\n\nInput: colors = \"abaac\", neededTime = [1,2,3,4,5]\nOutput: 3\nExplanation: In the above image, 'a' is blue, 'b' is red, and 'c' is green.\nBob can remove the blue balloon at index 2. This takes 3 seconds.\nThere are no longer two consecutive balloons of the same color.

The graph is fully traversed by Alice and Bob if starting from any node, they can reach all other nodes.\n\nReturn the maximum number of edges you can remove, or return -1 if Alice and Bob cannot fully traverse the graph.\n\nExample 1:\n\nInput: n = 4, edges = [[3,1,2],[3,2,3],[1,1,3],[1,2,4],[1,1,2],[2,3,4]]\nOutput: 2\nExplanation: If we remove the 2 edges [1,1,2] and [1,1,3]. The graph will still be fully traversable by Alice and Bob. Removing any additional edge will not make it so. So the maximum number of edges we can remove is 2.\n\nExample 2:\n\nInput: n = 4, edges = [[3,1,2],[3,2,3],[1,1,4],[2,1,4]]\nOutput: 0\nExplanation: Notice that removing any edge will not make the graph fully traversable by Alice and Bob.\n\nExample 3:\n\nInput: n = 4, edges = [[3,2,3],[1,1,2],[2,3,4]]\nOutput: -1\nExplanation: In the current graph, Alice cannot reach node 4 from the other nodes. Likewise, Bob cannot reach 1. Therefore it's impossible to make the graph fully traversable.\n\nConstraints:\n\n- 1 <= n <= 10^5\n- 1 <= edges.length <= min(10^5, 3 * n * (n - 1) / 2)\n- edges[i].length == 3\n- 1 <= type_i <= 3\n-

3 + 4 = 8\nrequests[1] -> nums[0] + nums[1] = 2 + 1 = 3\nTotal sum: 8 + 3 = 11.\nA permutation with a higher total sum is [3,5,4,2,1] with the following result:\nrequests[0] -> nums[1] + nums[2] + nums[3] = 5 + 4 + 2 = 11\nrequests[1] -> nums[0] + nums[1] = 3 + 5 = 8\nTotal sum: 11 + 8 = 19, which is the best that you can do.\n\nExample 2:\n\nInput: nums = [1,2,3,4,5,6], requests = [[0,1]]\nOutput: 11\nExplanation: A permutation with the max total sum is [6,5,4,3,2,1] with request sums [11].\n\nExample 3:\n\nInput: nums = [1,2,3,4,5,10], requests = [[0,2],[1,3],[1,1]]\nOutput: 47\nExplanation: A permutation with the max total sum is [4,10,5,3,2,1] with request sums [19,18,10].\n\nConstraints:\n\n- n == nums.length\n- 1 <= n <= 10^5\n- 0 <= nums[i] <= 10^5\n- 1 <=

It is not allowed to remove the whole array.\n\nReturn the length of the smallest subarray that you need to remove, or -1 if it's impossible.\n\nA subarray is defined as a contiguous block of elements in the array.\n\nExample 1:\n\nInput: nums = [3,1,4,2], p = 6\nOutput: 1\nExplanation: The sum of the elements in nums is 10, which is not divisible by 6. We can remove the subarray [4], and the sum of the remaining elements is 6, which is divisible by 6.\n\nExample 2:\n\nInput: nums = [6,3,5,2], p = 9\nOutput: 2\nExplanation: We cannot remove a single element to get a sum divisible by 9. The best way is to remove the subarray [5,2], leaving us with [6,3] with sum 9.\n\nExample 3:\n\nInput: nums = [1,2,3], p = 3\nOutput: 0\nExplanation: Here the sum is 6. which is already divisible by 3.

where targetGrid[row][col] is the color in the position (row, col) of the grid.\n\nReturn true if it is possible to print the matrix targetGrid, otherwise, return false.\n\nExample 1:\n\nInput:

+{"question_id": 1599, "task_id": "maximum-profit-of-operating-a-centennial-wheel", "difficulty": "Medium", "problem_description": "You are the operator of a Centennial Wheel that has four gondolas, and each gondola has room for up to four people. You have the ability to rotate the gondolas counterclockwise, which costs you runningCost dollars.\n\nYou are given an array customers of length n where customers[i] is the number of new customers arriving just before the i^th rotation (0-indexed). This means you must rotate the wheel i times before the customers[i] customers arrive. You cannot make customers wait if there is room in the gondola. Each customer pays boardingCost dollars when they board on the gondola closest to the ground and will exit once that gondola reaches the ground again.\n\nYou can stop the wheel at any time, including before serving all customers. If you decide to stop serving customers, all subsequent rotations are free in order to get all the customers down safely. Note that if there are currently more than four customers waiting at the wheel, only four will board the gondola, and the rest will wait for the next rotation.\n\nReturn the minimum number of rotations you need to perform to maximize your profit. If there is no scenario where the profit is positive, return -1.\n\nExample 1:\n\nInput: customers = [8,3], boardingCost = 5, runningCost = 6\nOutput: 3\nExplanation: The numbers written on the gondolas are the number of people currently there.\n1. 8 customers arrive, 4 board and 4 wait for the next gondola, the wheel rotates. Current profit is 4 * $5 - 1 * $6 = $14.\n2. 3 customers arrive, the 4 waiting board the wheel and the other 3 wait, the wheel rotates. Current profit is 8 * $5 - 2 * $6 = $28.\n3. The final 3 customers board the gondola, the wheel rotates. Current profit is 11 * $5 - 3 * $6 = $37.\nThe highest profit was $37 after rotating the wheel 3 times.\n\nExample 2:\n\nInput: customers = [10,9,6], boardingCost = 6, runningCost = 4\nOutput: 7\nExplanation:\n1. 10 customers arrive, 4 board and 6 wait for the next gondola, the wheel rotates. Current profit is 4 * $6 - 1 * $4 = $20.\n2. 9 customers arrive, 4 board and 11 wait (2 originally waiting, 9 newly waiting), the wheel rotates. Current profit is 8 * $6 - 2 * $4 = $40.\n3. The final 6 customers arrive, 4 board and 13 wait, the wheel rotates. Current profit is 12 * $6 - 3 * $4 = $60.\n4. 4 board and 9 wait, the wheel rotates. Current profit is 16 * $6 - 4 * $4 = $80.\n5. 4 board and 5 wait, the wheel rotates. Current profit is 20 * $6 - 5 * $4 = $100.\n6. 4 board and 1 waits, the wheel rotates. Current profit is 24 * $6 - 6 * $4 = $120.\n7. 1 boards, the wheel rotates. Current profit is 25 * $6 - 7 * $4 = $122.\nThe highest profit was $122 after rotating the wheel 7 times.\n\nExample 3:\n\nInput: customers = [3,4,0,5,1], boardingCost = 1, runningCost = 92\nOutput: -1\nExplanation:\n1. 3 customers arrive, 3 board and 0 wait, the wheel rotates. Current profit is 3 * $1 - 1 * $92 = -$89.\n2. 4 customers arrive, 4 board and 0 wait, the wheel rotates. Current profit is 7 * $1 - 2 * $92 = -$177.\n3. 0 customers arrive, 0 board and 0 wait, the wheel rotates. Current profit is 7 * $1 - 3 * $92 = -$269.\n4. 5 customers arrive, 4 board and 1 waits, the wheel rotates. Current profit is 11 * $1 - 4 * $92 = -$357.\n5. 1 customer arrives, 2 board and 0 wait, the wheel rotates. Current profit is 13 * $1 - 5 * $92 = -$447.\nThe profit was never positive, so return -1.\n\nConstraints:\n\n- n == customers.length\n- 1 <= n <= 10^5\n- 0 <= customers[i] <= 50\n- 1 <= boardingCost,

Each building has a number of employees. It's transfer season, and some employees want to change the building they reside in.\n\nYou are given an array requests where requests[i] = [from_i, to_i] represents an employee's request to transfer from building from_i to building to_i.\n\nAll buildings are full, so a list of requests is achievable only if for each building, the net change in employee transfers is zero. This means the number of employees leaving is equal to the number of employees moving in. For example if n = 3 and two employees are leaving building 0, one is leaving building 1, and one is leaving building 2, there should be two employees moving to building 0, one employee moving to building 1, and one employee moving to building 2.\n\nReturn the maximum number of achievable requests.\n\nExample 1:\n\nInput: n = 5, requests = [[0,1],[1,0],[0,1],[1,2],[2,0],[3,4]]\nOutput:

+{"question_id": 1606, "task_id": "find-servers-that-handled-most-number-of-requests", "difficulty": "Hard", "problem_description": "You have k servers numbered from 0 to k-1 that are being used to handle multiple requests simultaneously. Each server has infinite computational capacity but cannot handle more than one request at a time. The requests are assigned to servers according to a specific algorithm:\n\n- The i^th (0-indexed) request arrives.\n- If all servers are busy, the request is dropped (not handled at all).\n- If the (i % k)^th server is available, assign the request to that server.\n- Otherwise, assign the request to the next available server (wrapping around the list of servers and starting from 0 if necessary). For example, if the i^th server is busy, try to assign the request to the (i+1)^th server, then the (i+2)^th server, and so on.\n\nYou are given a strictly increasing array arrival of positive integers, where arrival[i] represents the arrival time of the i^th request, and another array load, where load[i] represents the load of the i^th request (the time it takes to complete). Your goal is to find the busiest server(s). A server is considered busiest if it handled the most number of requests successfully among all the servers.\n\nReturn a list containing the IDs (0-indexed) of the busiest server(s). You may return the IDs in any order.\n\nExample 1:\n\nInput: k = 3, arrival = [1,2,3,4,5], load = [5,2,3,3,3]\nOutput: [1]\nExplanation:\nAll of the servers start out available.\nThe first 3 requests are handled by the first 3 servers in order.\nRequest 3 comes in. Server 0 is busy, so it's assigned to the next available server, which is 1.\nRequest 4 comes in. It cannot be handled since all servers are busy, so it is dropped.\nServers 0 and 2 handled one request each, while server 1 handled two requests. Hence server 1 is the busiest server.\n\nExample 2:\n\nInput: k = 3, arrival = [1,2,3,4], load = [1,2,1,2]\nOutput: [0]\nExplanation:\nThe first 3 requests are handled by first 3 servers.\nRequest 3 comes in. It is handled by server 0 since the server is available.\nServer 0 handled two requests, while servers 1 and 2 handled one request each. Hence server 0 is the busiest server.\n\nExample 3:\n\nInput: k = 3, arrival = [1,2,3], load = [10,12,11]\nOutput: [0,1,2]\nExplanation: Each server handles a single request, so they are all considered the busiest.\n\nConstraints:\n\n- 1 <= k <= 10^5\n- 1 <= arrival.length, load.length <= 10^5\n- arrival.length == load.length\n- 1 <= arrival[i], load[i] <= 10^9\n- arrival is strictly

+{"question_id": 1610, "task_id": "maximum-number-of-visible-points", "difficulty": "Hard", "problem_description": "You are given an array points, an integer angle, and your location, where location = [pos_x, pos_y] and points[i] = [x_i, y_i] both denote integral coordinates on the X-Y plane.\n\nInitially, you are facing directly east from your position. You cannot move from your position, but you can rotate. In other words, pos_x and pos_y cannot be changed. Your field of view in degrees is represented by angle, determining how wide you can see from any given view direction. Let d be the amount in degrees that you rotate counterclockwise. Then, your field of view is the inclusive range of angles [d - angle/2, d + angle/2].\n\nYou can see some set of points if, for each point, the angle formed by the point, your position, and the immediate east direction from your position is in your field of view.\n\nThere can be multiple points at one coordinate. There may be points at your location, and you can always see these points regardless of your rotation. Points do not obstruct your vision to other points.\n\nReturn the maximum number of points you can see.\n\nExample 1:\n\nInput: points = [[2,1],[2,2],[3,3]], angle = 90, location = [1,1]\nOutput: 3\nExplanation: The shaded region represents your field of view. All points can be made visible in your field of view, including [3,3] even though [2,2] is in front and in the same line of sight.\n\nExample 2:\n\nInput: points = [[2,1],[2,2],[3,4],[1,1]], angle = 90, location = [1,1]\nOutput: 4\nExplanation: All points can be made visible in your field of view, including the one at your location.\n\nExample 3:\n\nInput: points = [[1,0],[2,1]], angle = 13, location = [1,1]\nOutput: 1\nExplanation: You can only see one of the two points, as shown above.\n\nConstraints:\n\n- 1 <= points.length <= 10^5\n- points[i].length == 2\n- location.length == 2\n- 0

false.\n\nNotice that x + y denotes the concatenation of strings x and y.\n\nExample 1:\n\nInput: a = \"x\", b = \"y\"\nOutput: true\nExplaination: If either a or b are palindromes the answer is true since you can split in the following way:\na_prefix = \"\", a_suffix = \"x\"\nb_prefix = \"\", b_suffix = \"y\"\nThen, a_prefix + b_suffix = \"\" + \"y\" = \"y\", which is a palindrome.\n\nExample 2:\n\nInput: a = \"xbdef\", b = \"xecab\"\nOutput: false\n\nExample 3:\n\nInput: a = \"ulacfd\", b = \"jizalu\"\nOutput: true\nExplaination: Split them at index 3:\na_prefix = \"ula\", a_suffix = \"cfd\"\nb_prefix = \"jiz\", b_suffix = \"alu\"\nThen, a_prefix + b_suffix = \"ula\" + \"alu\" = \"ulaalu\", which is a palindrome.\n\nConstraints:\n\n- 1 <= a.length, b.length <= 10^5\n- a.length == b.length\n- a and b consist of lowercase English letters\n", "canonical_tests": {"language": "python", "source": "def check(candidate):\n assert candidate(a = \"abcdefg\",b = \"gfedcba\") == True\n

All the coordinates are integral coordinates on the X-Y plane, and the distance between the two coordinates is the Euclidean distance.\n\nYou are also given an integer radius where a tower is reachable if the distance is less than or equal to radius. Outside that distance, the signal becomes garbled, and the tower is not reachable.\n\nThe signal quality of the i^th tower at a coordinate (x, y) is calculated with the formula ⌊q_i / (1 + d)⌋, where d is the distance between the tower and the coordinate. The network quality at a coordinate is the sum of the signal qualities from all the reachable towers.\n\nReturn the array [c_x, c_y] representing the integral coordinate (c_x, c_y) where the network quality is maximum. If there are multiple coordinates with the same network quality, return the lexicographically minimum non-negative coordinate.\n\nNote:\n\n- A coordinate (x1, y1) is lexicographically smaller than (x2, y2) if either:\n - x1 < x2, or\n - x1 == x2 and y1 < y2.\n- ⌊val⌋ is the greatest integer less than or equal to val (the floor function).\n\nExample 1:\n\nInput: towers = [[1,2,5],[2,1,7],[3,1,9]], radius = 2\nOutput: [2,1]\nExplanation: At coordinate (2, 1) the total quality is 13.\n- Quality of 7 from (2, 1) results in ⌊7 / (1 + sqrt(0)⌋ = ⌊7⌋ = 7\n- Quality of 5 from (1, 2) results in ⌊5 / (1 + sqrt(2)⌋ = ⌊2.07⌋ = 2\n- Quality of 9 from (3, 1) results in ⌊9 / (1 + sqrt(1)⌋ = ⌊4.5⌋ = 4\nNo other coordinate has a higher network quality.\n\nExample 2:\n\nInput: towers = [[23,11,21]], radius = 9\nOutput: [23,11]\nExplanation: Since there is only one tower, the network quality is highest right at the tower's location.\n\nExample 3:\n\nInput: towers =

For the upcoming tournament, you want to choose the team with the highest overall score. The score of the team is the sum of scores of all the players in the team.\n\nHowever, the basketball team is not allowed to have conflicts. A conflict exists if a younger player has a strictly higher score than an older player. A conflict does not occur between players of the same age.\n\nGiven two lists, scores and ages, where each scores[i] and ages[i] represents the score and age of the i^th player, respectively, return the highest overall score of all possible basketball teams.\n\nExample 1:\n\nInput: scores = [1,3,5,10,15], ages = [1,2,3,4,5]\nOutput: 34\nExplanation: You can choose all the players.\n\nExample 2:\n\nInput: scores = [4,5,6,5], ages = [2,1,2,1]\nOutput: 16\nExplanation: It is best to choose the last 3 players. Notice that you are allowed to choose multiple people of the same age.\n\nExample 3:\n\nInput: scores = [1,2,3,5], ages = [8,9,10,1]\nOutput: 6\nExplanation: It is best to choose the first 3 players.\n\nConstraints:\n\n- 1 <= scores.length, ages.length <= 1000\n- scores.length == ages.length\n- 1 <= scores[i] <= 10^6\n- 1 <= ages[i] <= 1000\n", "canonical_tests": {"language": "python",

Two different cities with labels x and y are directly connected by a bidirectional road if and only if x and y share a common divisor strictly greater than some threshold. More formally, cities with labels x and y have a road between them if there exists an integer z such that all of the following are true:\n\n- x % z == 0,\n- y % z == 0, and\n- z > threshold.\n\nGiven the two integers, n and threshold, and an array of queries, you must determine for each queries[i] = [a_i, b_i] if cities a_i and b_i are connected directly or indirectly. (i.e. there is some path between them).\n\nReturn an array answer, where answer.length == queries.length and answer[i] is true if for the i^th query, there is a path between a_i and b_i, or answer[i] is false if there is no path.\n\nExample 1:\n\nInput: n = 6, threshold = 2, queries = [[1,4],[2,5],[3,6]]\nOutput: [false,false,true]\nExplanation: The divisors for each number:\n1: 1\n2: 1, 2\n3: 1, 3\n4: 1, 2, 4\n5: 1, 5\n6: 1, 2, 3, 6\nUsing the underlined divisors above the threshold, only cities 3 and 6 share a common divisor, so they are the\nonly ones directly connected. The result of each query:\n[1,4] 1 is not connected to 4\n[2,5] 2 is not connected to 5\n[3,6] 3 is connected to 6 through path 3--6\n\nExample 2:\n\nInput: n = 6, threshold = 0, queries = [[4,5],[3,4],[3,2],[2,6],[1,3]]\nOutput: [true,true,true,true,true]\nExplanation: The divisors for each number are the same as the previous example. However, since the threshold is 0,\nall divisors can be used. Since all numbers share 1 as a divisor, all cities are connected.\n\nExample 3:\n\nInput: n = 5, threshold = 1, queries = [[4,5],[4,5],[3,2],[2,3],[3,4]]\nOutput: [false,false,false,false,false]\nExplanation: Only cities 2 and 4 share a common divisor 2 which is strictly greater than the threshold 1, so they are the only ones directly connected.\nPlease notice that there can be multiple queries for the same pair of nodes [x, y], and that the query [x, y] is equivalent to the query [y, x].\n\nConstraints:\n\n- 2 <= n <= 10^4\n- 0 <= threshold <= n\n- 1 <=

route of [1,3,5,3,5] has a maximum absolute difference of 2 in consecutive cells.\nThis is better than the route of [1,2,2,2,5], where the maximum absolute difference is 3.\n\nExample 2:\n\nInput: heights = [[1,2,3],[3,8,4],[5,3,5]]\nOutput: 1\nExplanation: The route of [1,2,3,4,5] has a maximum absolute difference of 1 in consecutive cells, which is better than route [1,3,5,3,5].\n\nExample

It is calculated using the following rules:\n\n- The rank is an integer starting from 1.\n- If two elements p and q are in the same row or column, then:\n - If p < q then rank(p) < rank(q)\n - If p == q then rank(p) == rank(q)\n - If p > q then rank(p) > rank(q)\n- The rank should be as small as possible.\n\nThe test cases are generated so that answer is unique under the given rules.\n\nExample 1:\n\nInput: matrix = [[1,2],[3,4]]\nOutput: [[1,2],[2,3]]\nExplanation:\nThe rank of matrix[0][0] is 1 because it is the smallest integer in its row and column.\nThe rank of matrix[0][1] is 2 because matrix[0][1] > matrix[0][0] and matrix[0][0] is rank 1.\nThe rank of matrix[1][0] is 2 because matrix[1][0] > matrix[0][0] and matrix[0][0] is rank 1.\nThe rank of matrix[1][1] is 3 because matrix[1][1] > matrix[0][1], matrix[1][1] > matrix[1][0], and both matrix[0][1] and matrix[1][0] are rank 2.\n\nExample 2:\n\nInput: matrix = [[7,7],[7,7]]\nOutput: [[1,1],[1,1]]\n\nExample 3:\n\nInput: matrix = [[20,-21,14],[-19,4,19],[22,-47,24],[-19,4,19]]\nOutput: [[4,2,3],[1,3,4],[5,1,6],[1,3,4]]\n\nConstraints:\n\n- m == matrix.length\n- n == matrix[i].length\n- 1 <= m, n <= 500\n-
