I want to check if the current time is "close" to 9pm UTC. I have the following code to a.) get "now" and convert it to UTC time and b.) get 9pm utc time.
Based off when I run it, it looks like it's running. However, I usually use scripting languages, and this looks absolutely crazy to me. I don't necessarily want to ... |
C23 has introduced attribute specifier sequences. Consequently, the header below attempts to conditionally define macros for these sequences (for my own use cases). In cases where a compiler does not yet support them but does support GNU C's attributes, the macros will expand to utilize GNU C's attributes, provided equ... |
This is a follow-up question for A recursive_transform_reduce Function for Various Type Arbitrary Nested Iterable Implementation in C++ and recursive_invocable and recursive_project_invocable Concept Implementation in C++. I am trying to implement another version recursive_transform_reduce function which takes unwrap_l... |
I am going to do a math competition which allows writing programs to solve problems.
The code attempts to solve problem 25 from the Purple Comet Spring 2004 Mathematics Meet:
In the addition problem

The problem is:
Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] where i, j and k are distinct and nums[i] + nums[j] + nums[k] == 0.
The solution set must not contain duplicate triplets and the order of the output and the order of the triplets does not matter.
This is my code:

I'm working with an API, where the url can be constructed with setting_ids. To more clearly indicate the functionality of the setting ids I am mapping them to a WriterClass' methods, with relevant names.
In the code below these are method_a to method_c, in the true application this is a list of ~250 settings.
The funct... |
let currentWeekNumber = 1; // Initial week number
function getWeeklyDates(year, month, weekNumber) {
const dates = [];
// Set the first day of the month
const firstDay = new Date(year, month - 1, 1);
// Calculate the offset to the first day of the week (assuming Sunday is the first day)

The goal is to take an array of numbers, have a max weight (saying 40%), and if any number above the max_num = sum * weight is present, remove the excess and distribute it over the sum of numbers that are below max_num based on their own weights.
The code is designed to be able to take a sum of any number, although in ... |
This is a follow-up question for A recursive_transform_reduce Template Function with Unwrap Level Implementation in C++. To fix the issue mentioned in G. Sliepen's answer, I updated the test cases and recursive_transform_reduce itself. Please check them again. If there is anything I missed, please let me know.
Test Cas... |
