public class GraphDriver {

 public static void main(String[] args)
 {
  BFSGraph g=new BFSGraph();
  g.addVertex('A');
  g.addVertex('B');
  g.addVertex('C');
  g.addVertex('D');
  g.addVertex('E');
  g.addVertex('F');
  g.addVertex('G');
  g.addVertex('H');
 
  g.addEdge(0, 1);
  g.addEdge(1, 2);
  g.addEdge(1, 7);
  g.addEdge(2, 3);
  g.addEdge(2, 4);
  g.addEdge(7, 4);
  g.addEdge(4, 5);
  g.addEdge(4, 6);
  g.bfs();
 }
