Solution: Find K Pairs with Smallest Sums

Understand how to find the k pairs with the smallest sums from two sorted arrays by implementing a min heap-based k-way merge. Learn to optimize performance compared to brute force, analyze time and space complexities, and apply this approach to solve coding interview problems effectively.

We'll cover the following...

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 chosen from list2.

Your task is to return the k pairs (u1, v1),(u2, v2),...,(uk, vk)(u1, \space v1), (u2, \space v2), ..., (uk, \space vk) whose sums u1+v1,u2+v2,...,uk+vku1 + v1, u2 + v2, ..., uk + vk ...
