What is the best sorting algorithm for large datasets?

The best sorting algorithm for large datasets often depends on the specific use case, but QuickSort and MergeSort are popular choices due to their efficiency.

Can you explain why QuickSort is preferred?

QuickSort is preferred because it has an average time complexity of O(n log n) and performs well in practice for large datasets.

Are there any scenarios where MergeSort is better?

Yes, MergeSort is stable and works well for linked lists and when you need to sort data that doesn't fit into memory.

What about other algorithms like HeapSort?

HeapSort is also O(n log n) and has a good worst-case performance, but it generally has a larger constant factor compared to QuickSort.

How do I choose the right algorithm for my data?

Consider factors like data size, whether the data is partially sorted, memory constraints, and whether you need stability in sorting.
