e58a5e6842 Update tim_sort.py (#972)
* Update tim_sort.py


Update tim_sort.py

The previous algorithm was skipping numbers, according to issue #959, and my own tests.
The version I am applying uses a while loop, which works correctly and is easier to compute, as there is no break statement.

* Update tim_sort.py

217615abf6 Removed Unused Variables (#949)
- Removed two unused variables.
- Changed `a` to `_` since the `a` variable is never used.

This addresses [3 alerts from lgtm](d55bbcd204/files/sorts/Odd-Even_transposition_parallel.py).

34889fc6d8 Update quick_sort.py (#928)
Use the last element as the first pivot, for it's easy to pop, this saves one element space.
Iterating with the original list saves half the space, instead of generate a new shallow copy list by slice method.

6e894ba3e8 Odd-Even Transposition Sort (#769)
* -Added a single-threaded implementation of odd-even transposition sort.

This is a modified bubble sort meant to work with multiple processors.
Since this is running on a single thread, it has the same running time
as bubble sort.

* -Added a parallel implementation of Odd-Even Transposition sort

This implementation uses multiprocessing to perform the swaps
at each step of the algorithm simultaneously.
