Restoring Shortest Path

BFS searching shortest path

That was hard! But now let's implement a method to find the shortest path between two vertices, not only length.

To do that, you have to know for each node where did it come from. So, let's add list pred that contains predcessor for i node. At the beginning, pred contains only -1.

Tarea

Modify bfs(start, end) so it returns a list of vertices between start and end nodes (both inclusive). If there is no path, return an empty list.

Do not forget to keep the path.
