Quick Sort Algorithm - Quick sort is a highly efficient sorting algorithm and is based on partitioning of array of data into smaller arrays.

Quick Sort Pseudocode · We are given with an input array · Choose pivot, here we are choosing the last element as our pivot · Now partition the array as per pivot.

In pseudocode, the quicksort algorithm becomes: // Sorts a (portion of an) array, divides it into partitions, then sorts those algorithm quicksort(A, lo, hi) ...

Quicksort. Quicksort(A,p,r) if (p < r) q <- Partition(A,p,r) Quicksort(A,p,q) Quicksort(A,q+1,r) } } Partition(A,p,r) x <- A[p] i <- p-1 j <- r+1 while ...

This implementation of quicksort uses a simple base case on lines 2 through 4 to check if the array is either empty, or contains one element.
