Tic-tac-toe is played by two players A and B on a 3 x 3 grid. Here are the rules of Tic-Tac-Toe: Players take turns placing characters into empty squares (" "). The first player A always places "X" characters, while the second player B always places "O" characters. "X" and "O" characters are always placed into empty squares, never on filled ones. The game ends when there are 3 of the same (non-empty) character filling any row, column, or diagonal. The game also ends if all squares are non-empty. No more moves can be played if the game is over. Given an array moves where each element is another array of size 2 corresponding to the row and column of the grid where they mark their respective character in the order in which A and B play. Return the winner of the game if it exists (A or B), in case the game ends in a draw return "Draw", if there are still movements to play return "Pending". You can assume that moves is valid (It follows the rules of Tic-Tac-Toe), the grid is initially empty and A will play first. Example 1: Input: moves = [[0,0],[2,0],[1,1],[2,1],[2,2]] Output: "A" Explanation: "A" wins, he always plays first. "X " "X " "X " "X " "X " " " -> " " -> " X " -> " X " -> " X " " " "O " "O " "OO " "OOX" Example 2: Input: moves = [[0,0],[1,1],[0,1],[0,2],[1,0],[2,0]] Output: "B" Explanation: "B" wins. "X " "X " "XX " "XXO" "XXO" "XXO" " " -> " O " -> " O " -> " O " -> "XO " -> "XO " " " " " " " " " " " "O " Example 3: Input: moves = [[0,0],[1,1],[2,0],[1,0],[1,2],[2,1],[0,1],[0,2],[2,2]] Output: "Draw" Explanation: The game ends in a draw since there are no moves to make. "XXO" "OOX" "XOX" Example 4: Input: moves = [[0,0],[1,1]] Output: "Pending" Explanation: The game has not finished yet. "X " " O " " " Constraints: 1 <= moves.length <= 9 moves[i].length == 2 0 <= moves[i][j] <= 2 There are no repeated elements on moves. moves follow the rules of tic tac toe.
