3. Consider the standard Shortest Path Problem. a) After we have solved the shortest path problem, we would now like to find the second shortest path (which may have the same cost). Provide a method to do this. b) Your relative insists that a certain edge must be used on the shortest path. Provide a method that finds the shortest path that includes that edge. 3.
