Problem Description
Rock, Paper, Scissors is a two player game, where each player simultaneously chooses one of the three items after counting to three. The game typically lasts a pre-determined number of rounds. The player who wins the most rounds wins the game. Given the number of rounds the players will compete, it is your job to determine which player wins after those rounds have been played. 

The rules for what item wins are as follows:

?Rock always beats Scissors (Rock crushes Scissors)
?Scissors always beat Paper (Scissors cut Paper)
?Paper always beats Rock (Paper covers Rock) 
 
Input
The first value in the input file will be an integer t (0 < t < 1000) representing the number of test cases in the input file. Following this, on a case by case basis, will be an integer n (0 < n < 100) specifying the number of rounds of Rock, Paper, Scissors played. Next will be n lines, each with either a capital R, P, or S, followed by a space, followed by a capital R, P, or S, followed by a newline. The first letter is Player 1抯 choice; the second letter is Player 2抯 choice.

Output
For each test case, report the name of the player (Player 1 or Player 2) that wins the game, followed by a newline. If the game ends up in a tie, print TIE.

题目大意：两个人玩石头、剪刀、步，第一个人赢了输出"Player 1"，第二个人赢了输出

"Player 2"，平手了就输出"TIE"。

思路：用两个数计算他们两个人的次数，平了不计。谁赢得次数多算谁赢。相等就是平手。

        char A,B;
        int NumA = 0,NumB = 0;
        for(int i = 0; i < N; ++i)
