[checkIO]Home 12.Xs and Os Referee

Tic-Tac-Toe, sometimes also known as Xs and Os, is a game for two players (X and O) who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal rows (NW-SE and NE-SW) wins the game.

But we will not be playing this game. You will be the referee for this games results. You are given a result of a game and you must determine if the game ends in a win or a draw as well as who will be the winner. Make sure to return "X" if the X-player wins and "O" if the O-player wins. If the game is a draw, return "D".

A game's result is presented as a list of strings, where "X" and "O" are players' marks and "." is the empty cell.

Input: A game result as a list of strings (unicode).

Output: "X", "O" or "D" as a string.

​

Example:

checkio([

"X.O",

"XX.",

"XOO"]) == "X"

checkio([

"OO.",

"XOX",

"XOX"]) == "O"

checkio([

"OOX",

"XXO",

"OXX"]) == "D"

​

* 가로, 세로, 대각선이 모두 O이면 O출력, X면 X출력

* 세개 다 같은 것이 없다면 D를 출력
