문제

Mari and Jüri are playing a computer game and arguing whose average score is higher. Write a program that based on their results decides whose average score is higher.

입력

The first line of input contains an integer $N$ (1ドル \le N \le 500,000円$). Each of the following $N$ lines contains a capital letter M or J and (separated by a space) an integer $P$ (0ドル \le P \le 10,000円$), where M stands for Mari and J for Jüri and $P$ is the number of points achieved during one playthrough by the corresponding player.

출력

The only line of output should consist of capital letter M if Mari's average score is higher than Jüri's, capital letter J if Jüri's average score is higher, or capital letter V if Mari's and Jüri's scores are equal. If a player has not played the game at all, then let that player's average score be 0ドル$.
