* -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.

This is a non-parallelized implementation of odd-even transpostiion sort.

Normally the swaps in each set happen simultaneously, without that the algorithm
|
|
is no better than bubble sort.
