# Algorithms 
This repository contains implementations of graph theory algorithms in Python. There is a [test folder][tf] in which all the algorithms are test with testcases using Python built-in [unittest][untest] module.<br>
The main [test.py][testpy] file is suggested by my friend u/MannerShark (on reddit).

These algorithms are originally from William Fisets Graph Theory Algorithm [Playlist][playlist]
