494fb4fb49 address merge_soft duplicate files (#1612) 
Here the old file merge_sort_fastest is renamed to unknown_sort. Because it is not merge sort algorithm.

Comments are updated accordingly.

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.

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.

a3ab980816 random_normaldistribution_quicksort 
This is for creating an algorithm implementing QuickSort Algorithm where the pivot element is chosen randomly between first and last elements of the array and the array elements are taken from a Standard Normal Distribution.

This is different from the ordinary quicksort in the sense, that it applies more to real life problems , where elements usually follow a normal distribution. Also the pivot is randomized to make it a more generic one.
