There may be more than one subarrays with sum as the given sum, return the first such subarray. Solution 1. O(n^2) runtime: enumerate all possible subarrays and check if there is at least subarray that sums to the given sum.
Given an array A of integers, return the number of (contiguous, non-empty) subarrays that have a sum divisible by K.Example 1:Input: A = [4,5,0,-2,-3,1], K = 5Output: 7Explanation: There are 7 subarrays with a sum divisible by K = 5:[4, 5, 0, -2, -3, 1], [5]...
