- Q4. Merge sort code
- Ans.
Merge sort is a divide-and-conquer algorithm that sorts an array by recursively dividing it into halves and merging sorted halves.

Merge the sub-arrays back together in sorted order.
Time complexity is O(n log n), making it efficient for large datasets.
Example: Sorting [38, 27, 43, 3, 9, 82, 10] results in [3, 9, 10, 27, 38, 43, 82].
