Consider the scenario of the game we have been seeing so far: The Revengers. Create a common interface via which the superheroes and the villains can be called easily. Use the concepts of the Facade design pattern.

You can refer the following steps to implement the solution:

$1.$ Create an abstract interface called Gamecharacter which the superheroes and the villians can implement

$2.$ Create $2$ classes: Superhero and Villian, which defines the the getCharacter function

$3.$ Create a class called TheUltimateGame which returns The Revengers and The Villians according to the input

$4.$ Write the client code which calls TheUltimateGame class
