Merge Sort | Divide and Conquer Approach | Step-by-Step Explanation

🚀 Learn how to solve the Merge Sort problem using the Divide and Conquer technique. Given an array arr[], sort the elements in ascending order using the Merge Sort algorithm. Merge Sort recursively divides the array into smaller subarrays, sorts them, and then merges them back together efficiently. Example Input: arr[] = [4, 1, 3, 9, 7] Output: [1, 3, 4, 7, 9] Key Concepts Covered ✅ Divide and Conquer ✅ Recursion ✅ Merge Function ✅ Stable Sorting Algorithm ✅ Time Complexity Analysis Complexity Time Complexity: O(n log n) Space Complexity: O(n) This solution is commonly asked in coding interviews and competitive programming contests.
