There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. C.A.R. Hoare
Quicksort is an efficient comparison sort algorithm. It can operate in place on the array, requiring small additional amounts of memory to perform sorting.
Quicksort can be faster than merge sort and heap sort. Quicksort 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 quick sort.
Unsorted array before sorting: [12, 34, 56, 23, 45, 78, 46] Sorted array After Quicksort sorting: [12, 23, 34, 45, 46, 56, 78]
