When should I use Quicksort in C++?

When should I use Quicksort in C++?

Quicksort is ideal for large datasets due to its average-case time complexity of O(n log n). It's also efficient for in-memory sorting.

Are there situations where I shouldn't use Quicksort?

Yes, avoid Quicksort for small datasets or when stability is required, as it is not a stable sort.

What are the advantages of using Quicksort over other sorting algorithms?

Quicksort is generally faster than other O(n log n) algorithms like Merge Sort due to better cache performance and lower constant factors.

Can you explain how the partitioning works in Quicksort?

Sure! In Quicksort, the array is divided into two sub-arrays based on a pivot element, where elements less than the pivot go to the left and those greater go to the right.
