Program to implement heap sort in c

It does this with the following steps:. The heap sort works as its name suggests — it begins by building a heap out of the data set, and then removing the largest item and placing it at the end of the sorted array. After removing the largest item, it reconstructs the heap and removes the largest remaining item and places it in the next open position from the end of the sorted array.

This is repeated until there are no items left in the heap and the sorted array is full. Elementary implementations require two arrays — one to hold the heap and the other to hold the sorted elements. CSS Functions- Part 2. CSS Shadows. CSS Media Queries. CSS Transitions. CSS Sizing Units.

Introsort is an alternative to heapsort that combines quicksort and heapsort to retain advantages of both: worst case speed of heapsort and average speed of quicksort. Systems concerned with security and embedded systems such as Linux Kernel use Heap Sort because of the O n log n upper bound on Heapsort's running time and constant O 1 upper bound on its auxiliary storage.

Although Heap Sort has O n log n time complexity even for the worst case, it doesn't have more applications compared to other sorting algorithms like Quick Sort, Merge Sort. However, its underlying data structure, heap, can be efficiently used if we want to extract the smallest or largest from the list of items without the overhead of keeping the remaining items in the sorted order.
