Find K Pairs with Smallest Sums

Understand how to find k pairs with the smallest sums from two sorted arrays by applying efficient k-way merge algorithms. Explore problem constraints, example scenarios, and implement your solution to prepare for coding interviews involving sorted data structures.

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 v ...
