[leetcode] 1497. Check If Array Pairs Are Divisible by k Description Given an array of integers arr of even length n and an integer k. We want to divide the array into exactly n / 2 pairs such that the sum of each pair is divisible by k. Return True If you ......
If the array already is k-periodic, then print 0. Input The first line of the input contains a pair of integers n, k (1 ≤ k ≤ n ≤ 100), where n is the length of the array and the value n is divisible by k. The second line contains the sequence of elements ...
