Describe your change:

Added the various complexities for the quick sort algorithm

  • Add an algorithm?
  • Fix a bug or typo in an existing algorithm?
  • Add or change doctests? -- Note: Please avoid changing both code and tests in a single pull request.
  • Documentation change?

I'm not sure if this space complexity analysis is accurate for this specific implementation. From Wikipedia, it seems like the $O(\log n)$ space complexity may only hold for a quick sort implementation that performs partitioning in place (though I may be wrong here). This Python implementation doesn't do in-place partitioning.

Yes, the best case is for in place it seems. I rechecked.
Since in place is the best way, should I implement with in-place method?
