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 $NN$ ($1\le N\le 5000001\; \backslash le\; N\; \backslash le\; 500\backslash ,000$). Each of the following $NN$ lines contains a capital letter M or J and (separated by a space) an integer $PP$ ($0\le P\le 100000\; \backslash le\; P\; \backslash le\; 10\backslash ,000$), where M stands for Mari and J for Jüri and $PP$ 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 $00$.
