WebJul 16, 2016 · Heap Sort is comparison based sorting algorithm. It uses binary heap data structure. Heap Sort can be assumed as improvised version of Selection Sort where we find the largest element and place it at end index. But unlike selection sort and like quick sort its time complexity is O (n*logn). WebThe steps we follow during heap sort are:- Initially build a max heap of elements in Arr. The root element contains the maximum element i.e. Arr [0]. So swap that element will last element of the heap and then heapify the heap excluding the last element.
