When should I use unstable sorting algorithms?

What is unstable sorting and when should I use it?

Unstable sorting algorithms do not maintain the relative order of equal elements. You might use them for efficiency when the order of equal elements is not important.

Can you give me examples of unstable sorting algorithms?

Sure! Examples include Quick Sort, Heap Sort, and Selection Sort.

Why would I choose an unstable sort over a stable one?

You might choose an unstable sort for better performance, especially with large datasets, where stability isn't a concern.

Are there situations where stability is crucial?

Yes, in scenarios like sorting records by multiple keys, stability ensures that equal elements retain their original order.
