Tennis score

This code challenge is about implementing a simple tennis score. Each set is one game. We highly encourage you to write tests to implement this solution.

Mechanism

The scoring system is rather simple:

• Each player can have either of these points in one game: 0 15 30 40
• If you have 40 and you win the ball you win the game, however there are special rules:
  • If both have 40 the players are deuce.
  • If the game is in deuce, the winner of a ball will have advantage and game ball.
  • If the player with advantage wins the ball he wins the game
  • If the player without advantage wins they are back at deuce.
