Problem: Merge Sorted Array

15 min

Understand how to merge two sorted arrays into a single sorted array using a k-way merge approach. This lesson helps you implement an efficient in-place merge that considers constraints and edge cases commonly found in coding interviews, enhancing your problem-solving skills.

Statement

You are given two integer arrays, nums1 and nums2, both sorted in non-decreasing order. You are also given two integers, m and n, representing the number of elements in nums1 and nums2, respectively.

Your task is to merge the elements of nums2 into nums1 so that nums1 becomes a single array sorted in non-decreasing order.

The merged result is stored in nums1, which has a total length of m + n. The first m positions contain the initial elements, the last n positions are placeholders (initialized to 0), and nums2 contains the n elements to merge.
