Problem: K Maximum Sum Combinations From Two Arrays

Medium

30 min

Explore how to identify the k maximum sum pairs from two arrays by combining elements and using heaps for efficient selection. This lesson helps you understand sorting and data structures to solve pair sum problems and manage time complexity effectively.

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 $≤ n$
