取消函数的使用改写上述代码

取消函数后，代码会变得更紧凑，但仍保持清晰。我们将直接在主循环中检查并执行消除操作。以下是取消函数后的代码：

import java.util.Scanner;

public class EliminationGame {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();
        int m = scanner.nextInt();

        int[][] board = new int[n][m];
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m; j++) {
                board[i][j] = scanner.nextInt();
            }
        }

        // 直接在主循环内检查并消除
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m - 2; j++) {
                if (eliminateLineAndColumn(board, i, j)) {
                    // 避免重复消除，仅在当前操作后更新对应区域
                    if (board[i][j] > 0) {
                        board[i][j] = 0;
                        if (i > 0 && eliminateLineAndColumn(board, i - 1, j)) continue;
                        if (j > 0 && eliminateLineAndColumn(board, i, j - 1)) continue;
                    }
                }
            }
        }

        // 输出结果
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < m; j++) {
                System.out.print(board[i][j] > 0 ? board[i][j] : "0 ");
            }
            System.out.println();
        }
    }

    // 合并检查和消除的逻辑
    private static boolean eliminateLineAndColumn(int[][] board, int row, int col) {
        int count = 1;
        if (checkLine(board, row, col) || checkColumn(board, col, row)) {
            for (int delta = 1; delta <= 2; delta++) {
                if (count >= 3) {
                    for (int dir = 0; dir < 2; dir++) {
                        int newRow = row + (dir == 0 ? delta : 0);
                        int newCol = col + (dir == 1 ? delta : 0);
                        while (newRow >= 0 && newRow < board.length && newCol >= 0 && newCol < board[0].length) {
                            board[newRow][newCol] = 0;
                            newRow += dir;
                            newCol += dir;
                        }
                    }
                    return true;
                }
                count = 1;
            }
        }
        return false;
    }
}

这段代码去掉了`checkLine`和`checkColumn`两个函数，将它们的逻辑整合到`eliminateLineAndColumn`方法中。这样处理虽然减少了函数调用，但是代码可能会稍微复杂一些。
