There are different ways to sort things, and in this article, we will learn how to use three popular sorting methods in Java: Bubble Sort, Merge Sort, and Quick Sort. We will explain these methods step by step in simple language. Bubble Sort in Java Bubble Sort is one of the easiest ...

Quicksort (Commun. ACM 4(7):321–322, 1961) remains one of the most studied algorithms in computer science. It is important not only as a practical sorting method, but also as a splendid teaching aid for introducing recursion and systematic algorithm development. The algorithm has been ...
The recursion part of the Quicksort algorithm is actually a reason why the average sorting scenario is so fast, because for good picks of the pivot element, the array will be split in half somewhat evenly each time the algorithm calls itself. So the number of recursive calls do not double...
Let's move to the next element 6, as 6 is smaller than pivot it will be in i=2. 9 will be in moved to i = 3. Comparing 3 with pivot and 3 is less than 10. So i will increment and become i=3 and 10 and 3 will be swapped. ...
Scala – Sorting Array in Ascending Order using Quicksort Sort Here, we will create an array of integers and then we will sort the created array using quicksort with recursion. Scala code to sort an array in ascending order using quicksort sort ...
Quicksort is a popular sorting algorithm that is often faster in practice compared to other sorting algorithms. It utilizes a divide-and-conquer strategy to quickly sort data items by dividing a large array into two smaller arrays. It was developed by Charles Antony Richard Hoare (commonly known...
