In a package named "execution" create a Scala class named "Team" and a Scala object named "Referee". Team will have: • State values of type Int representing the strength of the team's offense and defense with a constructor to set these values. The parameters for the constructor should be offense then defense • A third state variable named "score" of type Int that is not in the constructor, is declared as a var, and is initialized to O Referee will have: • A method named "playGame" that takes two Team objects as parameters and return type Unit. This method will alter the state of each input Team by setting their scores equal to their offense minus the other Team's defense. If a Team's offense is less than the other Team's defense their score should be 0 (no negative scores)A method named "declareWinner" that takes two Teams as parameters and returns the Team with the higher score. If both Teams have the same score, return a new Team object with offense and defense both set to O
