"""
|
|
This is a pure Python implementation of the bogosort algorithm,
|
|
also known as permutation sort, stupid sort, slowsort, shotgun sort, or monkey sort.
|
|
Bogosort generates random permutations until it guesses the correct one.
|

For doctests run following command:
|
|
python -m doctest -v bogo_sort.py
|
|
or
|
|
python3 -m doctest -v bogo_sort.py
|
|
For manual testing run:
|
|
python bogo_sort.py
