The partial sums of a list of integers [a1, a2, a3, ..., an] are
s1 = a1

Given two lists of numbers, a source and a pattern, reorder the source to match the relative ordering of the pattern. Any two entries of the reordered source should compare the same way as the entries at those same positions of the pattern.
For example, the input
s = [-5, 9, 4, 13, 11, -6, 0]
p = [7, -4, 1, -8, 4, -3, ... |
There is a game I like to play. It happens on a grid of finite size (but it's wrapped, like a sphere). On that grid, a random (integer-only) point is selected. Then, I, the user, am prompted for a coordinate input. If my input matches the random point exactly, I am told that I have won. Otherwise, I am told the point-w... |

Given an ASCII tower and the force of the wind, write a program or function to determine if the tower will balance or which way it will fall.
For example the first tower balances but the second falls over toward the left.

Your task is to create a program that will, given an input image, create an output image of the same size, where all pixels are ordered by hex value.
Your program may:
Sort the pixels from left to right and then down or first sort down in columns and then right. In any case, the top left pixel is the smallest, and the... |
Valve's KV file format is as follows (in pseudo-EBNF):
<pair> ::= <text> <value>
<value> ::= <text> | <block>
<text> ::= "\"" <char>* "\""
<block> ::= "{" <pair>* "}"
The parsing starts on <pair> state. Whitespace is allowed anywhere, but is only required between two consecutive <text> tokens ("a""b" is invalid, but "... |
Your task is make program that do following:
You should take number. (Positive, negative, fraction is possible input)
If it is negative, you reverse the quine. and negate that number (Become positive)
Then you repeat <integer part of the input number> times and print first <floor(fraction part of the input number*leng... |
Input
A list of between 1 and 255 positive integers (inclusive), each in the range 1 to 232 - 1 (inclusive).
Your input format does not need to be identical to the test cases.
Input without leading zeroes is required to be accepted.
Input with leading zeroes is not required to be accepted.
You may use whatever delimit... |
Write a program that takes two integers as an input; the first can be any integer and the second is less than or equal to the number of digits in the first number. Let these numbers be a and b respectively.
The program will do the following
Concatenate a minimal number of 1s to the end of a so the number of digits in ... |
