Mastering Merge Sort: Efficient Sorting Algorithm Explained | CodeZilla

🎥 Welcome to CodeZilla! In today's video, we dive into the world of sorting algorithms and explore the efficient and powerful Merge Sort algorithm.

🔍 What is Merge Sort?
Merge Sort is a classic divide-and-conquer algorithm that sorts an array or list by dividing it into smaller subarrays, sorting those subarrays, and then merging them back together. This approach ensures a time complexity of O(n log n), making it one of the most efficient sorting algorithms, especially for large datasets.

🧩 How Does Merge Sort Work?

Divide: Split the array into two halves until each subarray contains a single element.
Conquer: Recursively sort each subarray.
Combine: Merge the sorted subarrays to produce the final sorted array.
📋 Step-by-Step Breakdown:

Start with an unsorted array.
Recursively divide the array until each subarray has one element.
Merge the subarrays by comparing elements and arranging them in sorted order.
Continue merging until the entire array is sorted.
💡 Why Use Merge Sort?

Stable Sort: Maintains the relative order of equal elements.
Efficiency: Consistently performs well with O(n log n) time complexity.
Versatility: Works well with large datasets and linked lists.
🔧 Code Implementation:
We'll walk you through a step-by-step implementation of merge sort in various programming languages, including Python, Java, and C++.

📈 Performance Analysis:
Understand the best, worst, and average-case scenarios of merge sort, and see how it compares with other sorting algorithms like Quick Sort and Bubble Sort.
