CF1846B.Rudolph and Tic-Tac-Toe

Rudolph invented the game of tic-tac-toe for three players. It has classic rules, except for the third player who plays with pluses. Rudolf has a $3 \times 3$ field — the result of the completed game. Each field cell contains either a cross, or a nought, or a plus sign, or nothing. The game is won by the player who makes a horizontal, vertical or diagonal row of $3$'s of their symbols.

Rudolph wants to find the result of the game. Either exactly one of the three players won or it ended in a draw. It is guaranteed that multiple players cannot win at the same time.

鲁道夫为三位玩家发明了井字棋游戏。其规则与经典井字棋相同，但第三位玩家使用“加号（+）”作为自己的棋子。鲁道夫有一个 $3 \times 3$ 的棋盘——表示一局已结束的游戏结果。每个格子中要么是“叉（×）”，要么是“圈（○）”，要么是“加号（+）”，要么为空。当某位玩家在水平、垂直或对角线上连成三个自己符号时，该玩家获胜。

鲁道夫希望判定这局游戏的结果：三名玩家中恰好有一人获胜，或以平局结束。题目保证不会出现多名玩家同时获胜的情况。

The first line contains one integer $t$ ($1 \le t \le 10^4$) — the number of test cases.

Each test case consists of three lines, each of which consists of three characters. The symbol can be one of four: "X" means a cross, "O" means a nought, "+" means a plus, "." means an empty cell.

第一行包含一个整数 $t$（$1 \le t \le 10^4$）——测试用例的数量。

每个测试用例由三行组成，每行包含三个字符。字符可以是以下四种之一：“X” 表示叉号，“O” 表示圈号，“+” 表示加号，“.” 表示空格。

For each test case, print the string "X" if the crosses won, "O" if the noughts won, "+" if the pluses won, "DRAW" if there was a draw.

对于每个测试用例，如果十字（X）获胜，则输出字符串 "X"；如果圆圈（O）获胜，则输出 "O"；如果加号（+）获胜，则输出 "+"；如果平局，则输出 "DRAW"。
