Coding Interview Patterns: Topological Sort in Python

Topological Sort is a common pattern in coding interview questions. In this video I describe the algorithm for finding a valid topological sorting given a graph as well as the space and time complexity. I also write the code in python and explain it step by step.

p.s. I made a small typo at the end it should be if len(output) != vertices

This is my first video so any advice is appreciated!
