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 partitioning we have pivot in the final position. After recursively sorting the partition array, we get the sorted elements.C Quick Sort Algorithm:.
If n V right of V and all elements xi.
.Similar to, quicksort in C follows the principle of decrease and conquer, or as it is often called, divide and conquer. The quicksort algorithm is a sorting algorithm that works by selecting a pivot point, and thereafter partitioning the number set, or array, around the pivot point.Also known as partition-exchange sort, quicksort was developed by Tony Hoare, a British computer scientist, in 1959. Since its publishing in 1961, quicksort has become one of the top choices in sorting algorithms.

How To Sort An Array
The Quicksort ProcessOnce the partitioning is done, the group of elements smaller than the pivot element is placed before it, and the remaining, greater ones, after it. There are several variations of the quick sort algorithm, depending on what kind of element (or number) is selected as the pivot:. The first element as the pivot. The last element as the pivot. A random element as the pivot.

Median as the pivotThe main process in a quicksort algorithm is partitioning. If x is the pivot in an array, then the main intent of the sorting process is to put x at the right position in a sorted array, such that smaller elements precede x and greater elements follow it. T(n) = T(k) + T(n-k-1) + (n) → (i)T(k) and T(n-k-1) represents the two recursive calls in the quicksort algorithm. So, that was all about quicksort in C. The concept of sorting is one of the fundamental aspects of programming, hence, very important to have a good knowledge about.The programs that are detailed in the article for the implementation of a quicksort algorithm are two of the several possibilities.
Leaning it is best when experimented on your own.So, go and try it for yourself! You can consult other resources and some of the to understand the concept even better and further polish your programming skills as well.If you have some interesting way of implementing the quicksort algorithm, please brag about it in the comments.
