In this algorithm, we partition an unsorted array into two sub-arrays, in such a way that all the elements on the left side of that partition point (also called a pivot) should be smaller than the pivot, and all the elements on the right side of the pivot should be greater. After the first iteration of the quick sort algorithm, the chosen pivot point is placed in the list at its correct position. After the first iteration, we obtain two unordered sub-lists, and follow the same process again on these two sub-lists. Thus, the quick sort algorithm partitions the list into two parts and recursively applies the quick sort algorithm on these two sub-lists to sort the whole list.
We start by choosing a pivot point ...
