Congratulations

Congrats, you completed all necessary steps!

You implemented different functions that using BFS which may be useful for the Graph class. For now, the last tiny step is to think about some code reorganization and optimal usage.

You may notice that methods above usually contain similar code, and some methods can reuse others. For example, hasOneComponent() and getComponents() do the similar action, so we can combine them.

Let's go to the tasks!
