Minesweeper Board Update

Given a Minesweeper board board and one click position (clickRow, clickCol), return the board after applying the click. Cell meanings: M: an unrevealed mine. E: an unrevealed empty cell. B: a revealed blank cell with no adjacent mines. 1 to 8: a revealed cell whose value is the number of adjacent mines. X: a mine that was clicked and exploded. Update rules: If the clicked cell is M, change it to X and stop. If the clicked cell is E, count mines in its eight neighboring cells: If the count is positive, replace it with that digit. Otherwise, replace it with B and recursively reveal all adjacent unrevealed E cells. Cells not revealed by this click must remain unchanged. Input Format m n board[0] board[1] ... board[m-1] clickRow clickCol Each board row is a string of length n. Output Format Print the updated board, one row per line.
