Chapter 28.4, Problem 28.4.3CP

Show the output of the following code:

public class Test {

  public static void main(String[] args) {

    Graph<Character> graph = new UnweightedGraph<>();

    graph.addVertex(‘U’);

    graph.addVertex(‘V’);

    int indexForU = graph.getIndex(‘U’);

    int indexForV = graph.getlndex(‘V’);

    System.out.println (“indexForU is ” + indexForU);

    System.out.println(“indexForV is ” + indexForV);

    graph.addEdge(indexForU, indexForV);

    System.out.println(“Degree of U is ” +

      graph.getDegree(indexForU));

    System.out.println{“Degree of V is ” +

      graph.getDegree(indexForV));

  }

}
