A simple sorting technique that scans the sorted list, starting at the beginning, for the correct insertion point for each of the items from the unsorted list… Read more »

- Quick Sort Definition
A popular sorting algorithm that picks an element from the list, and reorder the list so that all elements which are less than the chosen element come before the chosen element.
- Divide and Conquer:
- (1) Divide the input instance into several instances of the same problem of
smaller size.
- (2) Recursively solve the problem on these smaller instances.
- (3) Combine the solutions for the smaller instances to a solution for the original instance (so after the recursive calls, we do some “extra work” to find the solution for our original instance).

quick SORT
The efficeieny of the quicksort depends on the pivot element. However the pivot element can also be choosen at random order or from the last element of the array
