Solve LeetCode 912 - Merge Sort (without recursion)

**Solve Leetcode 912 - Merge Sort 🍂**
In this video, we solve LeetCode 912 - Sort an Array using both Recursive and Iterative Merge Sort techniques. Merge Sort is a fundamental divide-and-conquer algorithm that splits an array into smaller parts, sorts them individually, and then merges them back in sorted order. We'll start with the classic recursive approach, diving into its implementation and explaining the recursive process. Then, we'll explore the Iterative Merge Sort, which eliminates the recursion and sorts the array in an iterative manner—great for understanding both perspectives!

By the end of this video, you'll have a clear understanding of the Merge Sort algorithm, its time complexity, and how to apply it effectively in coding interviews. 🌟 Perfect for strengthening your algorithmic thinking!
