Heap sort or Quicksort?

Hello, I have a question about heap sort and quicksort. Which one is faster and which one should i use?

4 hours ago, # |

Quicksort is faster than heapsort. Quicksort is usually about 2–3 times faster than heapsort. This is because quicksort's inner loop can be implemented efficiently on most architectures. Use quicksort if you prioritize speed and memory usage is not a concern, have a medium-sized dataset that fits in memory. Use heap sort if need a guarantee of worst-case performance (O(nlogn)), doing external sorting with large datasets.

Exploring the Worst Case Complexity of Quicksort (2015)

The quicksort algorithm has the best case complexity of O(n log n) when each pivot in the sort divides the list into two equal uniform pieces [1]. The worst case occurs when the pivot always divides the list into one lis...
