Heap Sort is a complex and fast sorting algorithm that organizes original collection into a heap which is a binary tree with every node higher that its children in order, then repeatedly takes the root node to the end of the sorted section and rebuilds the heap with remaining notes. The ba...
Sorting Algorithm Quick reference Complexity Worst case time O(nlgn)O(nlgn) Best case time O(n)O(n) Average case time O(nlgn)O(nlgn) Space O(1)O(1) Strengths: Fast. Heap sort runs in O(nlg(n))O(nlg(n)) time, which scales well as nn grows. Unlike quicksort,...

Heap Sort is a popular and efficient sorting algorithm in computer programming. Learning how to write the heap sort algorithm requires knowledge of two types of data structures - arrays and trees. In this tutorial, you will understand the working of heap
