题目描述

Mike and Joe are playing a game with some stones. Specifically, they have nn piles of stones of sizes a1,a2,,ana_1, a_2, \ldots, a_n . These piles are arranged in a circle.

The game goes as follows. Players take turns removing some positive number of stones from a pile in clockwise order starting from pile 11 . Formally, if a player removed stones from pile ii on a turn, the other player removes stones from pile ((imodn)+1)((i\bmod n) + 1) on the next turn.

If a player cannot remove any stones on their turn (because the pile is empty), they lose. Mike goes first.

If Mike and Joe play optimally, who will win?

输入格式

Each test contains multiple test cases. The first line contains the number of test cases tt ( 1t10001 \le t \le 1000 ). Description of the test cases follows.

The first line of each test case contains a single integer nn ( 1n501 \le n \le 50 ) — the number of piles.

The second line contains nn integers a1,a2,,ana_1, a_2, \ldots, a_n ( 1ai1091 \le a_i \le 10^9 ) — the size of the piles.

输出格式

For each test case print the winner of the game, either "Mike" or "Joe" on its own line (without quotes).

说明/提示

In the first test case, Mike just takes all 3737 stones on his first turn.

In the second test case, Joe can just copy Mike's moves every time. Since Mike went first, he will hit 00 on the first pile one move before Joe does so on the second pile.
