Conclusion – Heap sort in data structure The heap sort works internally in the binary heap, which is a completely balanced binary tree that either has the largest value or the smallest value at its node. Thus, the heapify process is carried out recursively to get the sorted array, as shown...

Learning how to write the heap sort algorithm requires knowledge of two types of data structures - arrays and trees. The initial set of numbers that we want to sort is stored in an array e.g. [10, 3, 76, 34, 23, 32] and after sorting, we get a sorted array [3,10,23,32,34,...

The heap sort algorithm starts by using procedure BUILD-HEAP to build a heapon the input array A[1 . . n]. Since the maximum element of thearray stored at the root A[1], it can be put into its correct finalposition by exchanging it with A[n] (the last element in A).If we ...

Sort the subtrees in ascending order based on the value of the root node of each subtree. While there are still multiple subtrees, iteratively recombine the last two (from right to left). If the root of the second-to-last subtree has a left child, swap it to be the right child. ...
Heapsort is an O(n \log n) sorting algorithm that works by first constructing a heap out of the list and repeatedly pulling the root off the top of the heap and reconstructs it until there are no items left in the heap. The values that are pulled off of the top of the heap come...
