a program which returns the current state of a tennis game.

 

reminder: 

first scrore = 15 points, 

second scor = 30 p , 

third score = 40 ppoints. 

After a player reaches 40 ppoints, he can: 

Enter a DEUCE state if both players have scored the same number of times. 

Enter an ADVANTAGE state if both players scores at least three times and the player scored 1 time more than his opponent. 

WIN the game if he has scored at least four times and 2 times more than the other player. 

Implementation methode: public static string ComputeGameState(string nameP1, string nameP2, string[] wins) wich returns the current state of a game. 

nameP1: the name of first player, 

nameP2: name of second player. 

wins is an array listing the name of each ball's winner.

        string score1 = scoreP1 < 3 ? scoreNames[scoreP1] : "40";
