Let's play the minesweeper game (Wikipedia, online game)!
You are given an m x n char matrix board representing the game board where:
You are also given an integer array click where click = [clickr, clickc] represents the next click position among all the unrevealed squares ('M' or 'E').
Return the board after revealing this position according to the following rules:
Examples
Example 1
Input: board = [["E","E","E","E","E"],["E","E","M","E","E"],["E","E","E","E","E"],["E","E","E","E","E"]], click = [3,0]
Output: [["B","1","E","1","B"],["B","1","M","1","B"],["B","1","1","1","B"],["B","B","B","B","B"]]
Example 2
Input: board = [["B","1","E","1","B"],["B","1","M","1","B"],["B","1","1","1","B"],["B","B","B","B","B"]], click = [1,2]
Output: [["B","1","E","1","B"],["B","1","X","1","B"],["B","1","1","1","B"],["B","B","B","B","B"]]
Constraints
m == board.lengthn == board[i].length1 <= m, n <= 50board[i][j] is either 'M', 'E', 'B', or a digit from '1' to '8'.click.length == 20 <= clickr < m0 <= clickc < nboard[clickr][clickc] is either 'M' or 'E'.
