(20 minutes. Open notes)

  1. As isolated vertex in a graph is one that has no neighbors. Write a method for the myListGraph class called isolatedVertices that returns the isolated vertices in the graph, stored in a StringLinkList object. In other words, the first line of the method should be: 
    	public StringLinkList isolatedVertices()

  2. What is the worst case running time of the above method, as a function of n, the number of vertices in the graph. Justify your answer with a one-sentence explanation.
