Nullify The Matrix

题意翻译

Ashish 和 Jeel 在玩游戏，有一个 $n\times m$ 的棋盘，每个格子有一个非负整数的权值。 两个人轮流操作，每次操作先选择一个权值非 $0$ 的格子作为起点，然后选择起点右下角的一个格子作为终点，然后选择它们之间的一条最短路径，然后给起点的权值减一个正整数、路径上每个点的权值随意加减（也可以不改变），但是都不能改成负数。 不能操作（全变成 $0$）就输了，Ashish 先手，问谁必胜。

题目描述

Jeel and Ashish play a game on an $ n \times m $ matrix. The rows are numbered $ 1 $ to $ n $ from top to bottom and the columns are numbered $ 1 $ to $ m $ from left to right. They play turn by turn. Ashish goes first. Initially, each cell of the matrix contains a non-negative integer. Each turn, a player must perform all of the following actions in order. - Choose a starting cell $ (r_1, c_1) $ with non-zero value. - Choose a finishing cell $ (r_2, c_2) $ such that $ r_1 \leq r_2 $ and $ c_1 \leq c_2 $ . - Decrease the value of the starting cell by some positive non-zero integer. - Pick any of the shortest paths between the two cells and either increase, decrease or leave the values of cells on this path unchanged. Note that: - a shortest path is one that passes through the least number of cells; - all cells on this path excluding the starting cell, but the finishing cell may be modified; - the resulting value of each cell must be a non-negative integer; - the cells are modified independently and not necessarily by the same value. If the starting and ending cells are the same, then as per the rules, the value of the cell is decreased. No other operations are performed. The game ends when all the values become zero. The player who is unable to make a move loses. It can be shown that the game will end in a finite number of moves if both players play optimally. Given the initial matrix, if both players play optimally, can you predict who will win?

The first line contains a single integer $ t $ ( $ 1 \leq t \leq 10 $ ) — the number of test cases. The description of each test case is as follows. The first line of each test case contains two integers $ n $ and $ m $ ( $ 1 \leq n, m \leq 100 $ ) — the dimensions of the matrix. The next $ n $ lines contain $ m $ space separated integers $ a_{i,j} $ ( $ 0 \leq a_{i,j} \leq 10^6 $ ) — the values of each cell of the matrix.

输出格式

For each test case, if Ashish wins the game, print "Ashish", otherwise print "Jeel" (without the quotes).

说明

In the first test case, the only cell of the matrix is 0. There are no moves Ashish can make. Jeel is the winner. In the second test case, Ashish can choose $ (r_1, c_1) = (r_2, c_2) = (1,3) $ and reduce the cell to $ 0 $ , leaving $ [0, 0, 0] $ . Jeel cannot perform any moves. Ashish wins.
