So, now what is Quicksort ? Quicksort, or partition-exchange sort, is a sorting algorithm developed by Tony Hoare that, on average, makes O comparisons to sort n items. In the worst case, it makes O comparisons, though this behavior is rare. Quicksort is often faster in practice than other O algorithms. Additionally, quicksort's sequential and localized memory references work well with a cache. Quicksort is a comparison sort and, in efficient implementations, is not a stable sort. Quicksort can be implemented with an in-place partitioning algorithm, so the entire sort can be done with only O additional space used by the stack during the recursion. Properties of Quicksort :- The quick sort is an in-place, divide-and-conquer, massively recursive sort algorithm . The efficiency of the algorithm is majorly impacted by which element is chosen as the pivot point. The worst-case efficiency of the quick sort is o (n²) when the list is sorted and left most element is chosen as the p...
