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...

In this article, we explain the heap sort algorithm in Python. We cover sorting numeric and textual data in both ascending and descending order. Finally, we compare heap sort with quick sort and perform a benchmark. An algorithm is a step-by-step procedure to solve a problem or perform a...
Heap Sort Algorithm heap-sort uses max heap data structure to sort a sequence. The steps are: We need construct a max heap in place firstly, so that we can make sure that the bigest value locates on the first position of the heap. Swap the top value with the last value of the sequen...

Example of Heap Sort in C++ This technique uses binary heap which is constructed using a complete binary tree where the root node is greater than its two children nodes. Consider the given array of data sets. Let us go according to the algorithm. It says to select the highest element as ...
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. The initial set of numbers that we want to sort is stored in an array e.g. [10, 3, 76, ...
