Challenge 9 - Quick sort

[AbsoluteBeginner]

Sorting is an extremely well researched topic and extremely unlikely any of us will discover anything new that works well.  But that isn't the point, the point is researching something, thinking about it and writing code, testing the code and comparing it with other methods objectively.  So by all means, share your variants or maybe try to write the quicksort as originally suggested.

In that case, I will continue preparing my code for publication. Because it is interesting.
