WebIt is an in-place sorting algorithm and performs sorting in O(1) space complexity. Compared to quicksort, it has a better worst-case time complexity — O(nlog n). The best-case complexity is the same for both quick sort and heap sort — O(nlog n). Unlike merge sort, it does not require extra space.
