Example 1:
Input: board = [["a","a","a","."],[".",".",".","."]], x = 0, y = 3, player = "a"
Output: true
Explanation:
Example 2:
Input: board = [["a","b",".","."],["b","a",".","."],[".",".",".","."],[".",".",".","."]], x = 2, y = 2, player = "a"
Output: false
You are given an m x n board for a two-player game. Each cell is one of:
"." for empty"a" for player A"b" for player BGiven a move (x, y, player), simulate placing player at board[x][y] and return whether this move makes that player win.
A player wins if there are 4 consecutive pieces of that player in any direction: horizontal, vertical, diagonal (\), or anti-diagonal (/).
If board[x][y] is already occupied, return false.
Assume x and y are 0-indexed.
Placing at (0, 3) creates four consecutive "a" horizontally.
1 <= m, n <= 200board[i][j] is ".", "a", or "b"player is "a" or "b"0 <= x < m0 <= y < n
