## BFS: check if graph is one-component

In the previous method, we considered that the graph is one-component. That’s because if you start traversing at some node, you’ll visit only nodes from the same component. 

If there are some other components, you should start from vertices of another component.

This mini-course introduces the BFS Algorithm. It requires understanding the graph theory on base level, and Python programming language knowledge. This course is built on implementing step-by-step solutions and using `Graph` class implementation, so you have to understand Python OOP minimally. You have to be able to implement an algorithm by pseudocode.

Meet the BFS example and code, that you'll improve during the course.

Let's upgrade your code to make it faster and consistent.

Apply your knowledge to solve some algorithmic problems.
