The tasks for challenge #373 are as follows: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Task 373-1: Equal List Submitted by: Mohammad Sajid Anwar You are given two arrays of strings.

The tasks for challenge #372 are as follows: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Task 372-1: Rearrange Spaces Submitted by: Mohammad Sajid Anwar You are given a string text of words that are placed among a number of spaces. Write a script to rearrange the spaces so that there is an equal number of spaces between every pair of adjacent words and that number is maximised. If you can’t distribute, place the extra spaces at the end. Finally return the string. I use this procedure: Count available spaces s. Trim leading and trailing spaces. Split string to @words on spaces. Count gaps between words (n words means n-1 gaps). Form quotient q and remainder r of sp...

You can find it here: The Weekly Challenge The Weekly Challenge for the week of 2026-04-27 through 2026-05-03 is #371. The tasks for challenge #371 are as follows: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Task 371-1: Missing Letter Submitted by: Reinier Maliepaard You are given a sequence of 5 lowercase letters, with one letter replaced by ‘?’. Each letter maps to its position in the alphabet (‘a = 1’, ‘b = 2’, …, ‘z = 26’). The sequence follows a repeating pattern of step sizes between consecutive letters. The pattern is either a constant step (e.g., ‘+2, +2, +2, +2’) or a simple alternating pattern of two distinct steps (e.g., ‘+2, +3, +2, +3’). Example inputs: ("ac?gi", "ad?jm", "ae?mq", "acf?k", "beg?l") Expected outputs: e g i ...
