  Problem Set 4: Interface-based Programming In problem set 3, you developed a console-based version of the paper and pencil game Bulls and Cows. The solution consisted of one class BullsAndcows and a main function defining the game loop. The approach works nicely, but did not follow the Model-View-Controller paradigm The task for this problem set is to develop an interface-based solution for Bulls and Cows. In particular, you are asked to implement a console view for the application that satisfies the following specification pragma once include
