Find K Pairs with Smallest Sums

Explore how to identify the k pairs with the smallest sums from two sorted arrays. Understand the problem constraints and implement an efficient solution to merge pairs, which is essential for tackling coding interview questions involving sorted data and optimization.

Statement

You are given two integer arrays, list1 and list2, sorted in non-decreasing order, and an integer, k.

A pair (u, v)(u, \space v) is defined as one element uu chosen from list1 and one element vv ...
