Components Methods

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

Task

We can use getComponents() inside hasOneComponent() function, and return True if answer consists of one component. Let's leave getComponents() as it is, and change hasOneComponent() by calling getComponents() inside it, and analyzing the answer.
