The problem: Source: codewars Given an array of positive or negative integers $I = [i_1, .., i_n]$ , you have to produce a sorted array P of the form [ [$p$, sum of all $i_j$ of $I$ for which $p$ is a prime factor ($p$ positive) of $i_j$] …] P will be sorted by increasing order of the prime numbers. The final result has to be given as a string in Java, C#, C, C++ and as an array of arrays in other languages....

Problem: Source: Codewars.com The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: maxSequence({-2, 1, -3, 4, -1, 2, 1, -5, 4}); //should be 6: {4, -1, 2, 1} Easy case is when the list is made up of only positive numbers and the maximum sum is the sum of the whole array. If the list is made up of only negative numbers, return 0 instead....
