What are the best sorting algorithms for large datasets?

What are the best sorting algorithms for large datasets?

The best sorting algorithms for large datasets include Quick Sort, Merge Sort, and Heap Sort. Each has its own advantages.

Can you explain why Quick Sort is often preferred?

Quick Sort is preferred due to its average-case time complexity of O(n log n) and its efficient in-place sorting.

What about Merge Sort? When should I use it?

Merge Sort is stable and works well for large datasets that don't fit in memory, as it can handle external sorting.

Are there any algorithms that are better for nearly sorted data?

Yes, Insertion Sort is very efficient for nearly sorted data, with a time complexity of O(n) in the best case.
