Quicksort is an efficient comparison sorting algorithm. It can operate in place on an array, requiring small additional amounts of memory to perform sorting.
Quicksort can be faster than merge sort and heap sort. Quick sort is one of the divides and conquers strategy algorithm. It requires careful selection of pivot element. Even if the array nearly sorted or sorted the quicksort takes the same complexity. If the array nearly sorted, we can choose insertion sort for better complexity.
Write a program to implement the quicksort.
Unsorted array before sorting: [12, 34, 56, 23, 45, 78, 46] Sorted array After Quicksort sorting: [12, 23, 34, 45, 46, 56, 78]
