Quicksort program in c using array

Write a C program to implement Quick Sort using Arrays. Quick sort is a divide and conquer algorithm. Quick sort first divides a large list into two smaller sub-lists: the low elements and the high elements. Quick sort can then recursively sort the sub-lists.

In c quick sort we take the one element called as pivot,then we list all the smaller elements than pivot, and greater than pivot. After recursively sorting the partition array, we get the sorted elements. Table of Contents. Improve Article. Save Article. Like Article. It picks an element as pivot and partitions the given array around the picked pivot. There are many different versions of quickSort that pick pivot in different ways.

Always pick first element as pivot. Always pick last element as pivot implemented below Pick a random element as pivot. Pick median as pivot. What is the program of quick sort which has it's median as it's pivot? This will be the best case of quick sort in which partition process always picks the middle element as pivot. Recurrence for best case is O n log n. In-place idea is about space efficiency. Yes, Quick sort is an in-place algorithm. There is no need to allocate additional memory in the heap memory.

Quick sort works on divide and conquer technique. It picks an element as pivot from the given list or array and partition the given array around the picked pivot element.

Then data is compared with this pivot element, if it is smaller then put before pivot and if it is greater than pivot, it will be placed after pivot. Don't have an account? Sign Up.
