Quick Sort in Java2 min read

In this post, we will learn how to implement Quick Sort in java. First, we will start by understanding the Quick Sort algorithm.

Quick Sort Algorithm

Quicksort algorithm is a way of rearranging the elements in an array in ascending or descending order. Quicksort is another Divide and Conquer algorithm.

It takes two empty arrays to hold elements, the first is less than the pivot value and the second element greater than the pivot value, and then sort the element around it or inside it. It involves Swapping and partitioning a section of the array.

Time Complexity of Quick Sort:

  • Best case:  0(n log n)
  • Average case:  0(n log n)
  • Worst case:  0(n^2)
