In the algorithm, we make use of max_heapify and create_heap which are the first part of the algorithm. When using create_heap, we need to understand how the max-heap structure, as shown below, works. Because we make use of a binary tree, the bottom of the heap contains the maximum number of nodes. … Ver más The Heapsort algorithm mainly consists of two parts- converting the list into a heap and adding the max element from the heap to the end of the list, while maintaining the heap structure. For easy implementation, we … Ver más The worst case for heap sort might happen when all elements in the list are distinct.
