Extend the class of Exercise P-14.75 to support the update methods of the graph ADT.

In Exercise P-14.75

Implement the simplified graph ADT described in Exercise P-14.73, using the adjacency list structure.

In Exercise 73

Use an adjacencymatrix to implement a class supporting a simplified graph ADT that does not include update methods. Your class should include a constructor method that takes two collections—a collection V of vertex elements and a collection E of pairs of vertex elements—and produces the graph G that these two collections represent.
