Chapter 29.3, Problem 29.3.3CP

Show the output of the following code:

public class Test {

  public static void main(String[] args) {

    WeightedGraph<Character> graph = new WeightedGraph<>();

    graph.addVertex(‘U’);

    graph.addVertex(‘V’);

    int indexForU = graph.get Index(‘U’);

    int indexForV = graph.get Index(‘V’);

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

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

    graph.addEdge(indexForU, indexForV, 2.5);

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

      graph.getDegree(indexForU));

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

      graph.getDegree(indexForV));

    System.out.println(“Weight  of UV is ” +

      graph.getWeight(indexForU, index0fV));

  }

}
