A connected component in a graph is a maximal set of vertices that are mutually connected. Write a Graph client CCFinder that computes the connected components of a graph. Include a constructor that takes a Graph as an argument and computes all of the connected components using breadth-first search. Include a method areConnected \((v, w)\) that returns true if \(v\) and \(w\) are in the same connected component and false otherwise. Also add a method components () that returns the number of connected components.
