BFT and BFS

First, Copy and Paste the whole implemented class Graph to the Editor, and save it somewhere outside for safety.

BFS and BFT do the same action, too, but in bfs() we search until end vertex is found. Actually, we can pass unnecessary end node to the bft() and change algorithm a bit, but avoid using to almost the same functions bfs() and bft().

Task

Change the bft() function by adding an unnecessary vertex end as a parameter, so you could refactor it like the bfs() function.

Task

Change the bft() function by adding an unnecessary vertex end as a parameter, so you could refactor it like the bfs() function.
