## Write a c program to implement heap sort

In this article, we will discuss the Heapsort Algorithm. Heap sort processes the elements by creating the min-heap or max-heap using the elements of the given array.

Min-heap or max-heap represents the ordering of array in which the root element represents the minimum or maximum element of the array. Before knowing more about the heap sort, let's first see a brief description of Heap.

A heap is a complete binary tree, and the binary tree is a tree in which the node can have the impldment two children. A complete binary tree is a binary tree in which all the levels except the last level, i.

Heapsort is a popular and efficient sorting algorithm.

The concept of heap sort is to eliminate the elements one by one from the heap part of the list, and then insert them into the sorted part of the list. In heap sort, basically, there are two phases involved in the sorting of elements.

By using the heap sort algorithm, they are as follows custom masters essay editing site us. Now let's see the working x heap sort in detail by using an example. To understand it more clearly, let's take an unsorted array and try to sort it using heap sort. It will make the explanation **write a c program to implement heap sort** and easier.

Next, we qrite to delete the root element 89 from the max heap. To delete this node, we have to swap it with the last node, i. After deleting the root element, we again have to heapify it to convert it into max heap. After swapping the array element 89 with 11, and converting the heap into max-heap, the elements of array are. In the next step, again, we have to delete the root element 81 from the max heap. After swapping the array element 81 with 54 and converting the heap into max-heap, the elements of array are .

In the next step, we have to delete the root element 76 from the max heap again. After swapping the array element 76 with 9 and converting the heap into max-heap, the elements of array are.

In the next step, again we have to delete the root element 54 from the max heap. After swapping the array element 54 with 14 and converting the heap into max-heap, the elements of array are .

## What is Heap Data Structure?

In the next step, again we have to delete the root element 22 from the max heap. After swapping the array element 22 with 11 and converting the heap implemwnt max-heap, the elements of array are. In the next step, again we have to ideas for a level physics coursework the root element 14 from the max heap. After **write a c program to implement heap sort** the array element 14 with 9 and converting the heap into max-heap, the elements of array are.

In the next step, again we have to delete the root element 11 from the max heap.

After swapping the array element 11 with 9, the elements of array are. Now, let's see the time complexity of Heap sort in the best case, average case, and worst case.

We will also see the space complexity of Heapsort. The time complexity of heap sort is O n logn in all three cases best impoement, average case, and worst case.]
