Problem: K Maximum Sum Combinations From Two Arrays

hard

40 min

Explore how to identify the k largest sum combinations from two integer arrays by adding one element from each array. Learn to apply the top k elements pattern and use heaps to efficiently find and return these sums in non-increasing order.

Statement

You are given two integer arrays, arr1 and arr2, each of size $n$ . You are also given an integer 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 $0 ≤ i, j < n$ .

Note: The output should be sorted in non-increasing order.

Constraints:

$1 ≤ n ≤ 1000$
$1\leq$ arr1[i], arr2[i] $\leq 10^3$
$1 ≤$ k $≤ n$
