In quick sort we split the array into two parts and all the elements of one part is less than or equal to elements of other part for all possible indexes for both parts and if we sort these lines repeatedly then the entire array will be sorted. These are known as Divide and conquer ...
Quicksort is one of the fastest general-purpose sorting algorithms used in contemporary code bases. It utilizes the divide-and-conquer technique similar to the merge sort algorithm. Although, the former one depends on an operation commonly called partitioning. The original vector is split on the ...

Following are the implementations of Quick Sort algorithm in various programming languages −C C++ Java Python Open Compiler #include <stdio.h> #include <stdbool.h> #define MAX 7 int intArray[MAX] = { 4,6,3,2,1,9,7 }; void printline(int count) { int i; for (i = 0; i < ...

Now, let us have a look at the implementation of quicksort in Java. Thequicksort()function checks whether the argument array has more than one element. If the subarray has only one element or is empty, then it is already sorted, and the function returns. Else, the partitioning is perform...
1. The very first step in Quick Sort includes selecting an element as a pivot element. A pivot element is an element from the array which is selected to act as a division to a range of numbers. If we select ‘n’ as our pivot element, so the numbers from the array which are less...
