/**
* Description: Algorithms and Data Structures.
* Quick Sort is a fast sorting algoritm, which is used not only for educational purposes,
* but widely applied in practice. On the average, it has O(n log n) complexity, making quicksort suitable for sorting big data volumes.
* The divide-and-conquer strategy is used. Choose a pivot value. Partition. Rearrange elements in such way, that all elements which is lesser than the pivot
* go to the left part of the array and all elements greater than the pivot, to the right part of the array. Values equal to the pivot can stay
* in any part of the array.Apply quicksort algoritm recursively to the left and the right parts.
