Web14 sep. 2024 · Binary Heap; Steps to perform heap sort: We start by using Heapify to build a max heap of elements present in an array A. Once the heap is ready, the largest element will be present in the root node of the heap that is A[1]. Now swap the element at A[1] with the last element of the array, and heapify the max heap excluding the last element. WebHeaps. A heap is a tree-based data structure in which all the nodes of the tree are in a specific order.
