When should I use merge sort?

When should I use merge sort instead of quicksort?

Merge sort is preferred when you need stable sorting or when dealing with large datasets that don't fit in memory.

What are the advantages of merge sort over other sorting algorithms?

Merge sort has a guaranteed time complexity of O(n log n) and is stable, making it suitable for linked lists.

Are there any scenarios where merge sort is not a good choice?

Yes, merge sort can be less efficient for small datasets compared to algorithms like insertion sort.

Can you explain how merge sort works?

Sure! Merge sort divides the array into halves, sorts each half, and then merges them back together in order.
