Learn Programming - Breadth First Search (BFS) - Finding the shortest path through a Maze!

I saw a few of you enjoyed my last post on DFS or Depth First Search, so I made a tutorial on it's sister algorithm Breadth First Search (BFS), check it out below:

Computer scientists say this algorithm is optimal, basically it finds the shortest path through a maze. This has many applications such as computer networking. You can read more about the applications of BFS here:

In case you missed my last post on DFS, you can find it here:

Again, this tutorial is designed for absolute beginners so, if you don't understand something or need clarification, leave a comment below and I will answer as best I can! Thanks for welcoming me to the steemit community!
