Merge Two Sorted Arrays | First Step of Merge Sort Explained
In this video, we implement and understand how to merge two already sorted arrays into a single sorted array.
This merging logic is the core building block of the Merge Sort algorithm. Before understanding the full recursion of Merge Sort, it’s important to master this step first.
We go step-by-step through the logic, comparisons, and edge cases, building a strong foundation for understanding Merge Sort’s O(n log n) time complexity.
