Statement
You are given two integer arrays, arr1 and arr2, each of size k. Your task is to return the k largest sum combinations that can be formed by adding one element from arr1 and one element from arr2, for all possible pairs (arr1[i] + arr2[j]), where
Note: The output should be sorted in non-increasing order.
