Sort an Array Using Quicksort Algorithm

Explore how to sort an array of integers in ascending order using the quicksort algorithm. Learn the process of selecting a pivot, partitioning the array, and applying recursion to subarrays. Understand the efficiency of quicksort, with its typical time complexity of O(n log n) and space complexity of O(log n), enhancing your grasp of algorithm design and performance analysis.

We'll cover the following...

Statement

Given an array of integers nums, sort it in ascending order using the quicksort algorithm.

Example

Here’s an example of the quicksort algorithm:

g array Original array 0 1 2 3 4 55 23 26 2 25 array2 Sorted array 0 1 2 3 4 2 23 25 26 55

Sample input

[55, 23, 26, 2, 25]

Expected output

[2, 23, 25, 26, 55]

Try it yourself #

#include <iostream>
#include <vector>
using namespace std;
void QuickSort(vector<int> &nums, int size) { 
	// TODO: Write - Your - Code
	return;
}

Solution

Here is an overview of how the quicksort algorithm works:

  • Select a pivot element from the array
