上述问题用c语言代码解决

以下是用C语言实现的代码，其中`chessboard`数组表示棋盘，`size`表示棋盘大小，`x`和`y`表示当前处理的子棋盘左上角的坐标，`missing_x`和`missing_y`表示残缺的格子的坐标，`cover`表示当前处理的3格板的编号。

#include <stdio.h>

#define MAX_SIZE 1024

int chessboard[MAX_SIZE][MAX_SIZE];

void solve(int size, int x, int y, int missing_x, int missing_y, int cover) {
    if (size == 1) return;
    int half = size / 2;
    int center_x = x + half - 1;
    int center_y = y + half - 1;
    int next_cover = cover + 1;
    // 左上子棋盘
    if (missing_x <= center_x && missing_y <= center_y) {
        chessboard[center_x][center_y+1] = chessboard[center_x+1][center_y] = chessboard[center_x+1][center_y+1] = cover;
        solve(half, x, y, missing_x, missing_y, next_cover);
        solve(half, x, y+half, x+half-1, y+half, next_cover);
        solve(half, x+half, y, x+half, y+half-1, next_cover);
        solve(half, x+half, y+half, center_x+1, center_y+1, next_cover);
    }
    // 右上子棋盘
    else if (missing_x <= center_x && missing_y > center_y) {
        chessboard[center_x][center_y] = chessboard[center_x+1][center_y] = chessboard[center_x+1][center_y+1] = cover;
        solve(half, x, y, x+half-1, y+half-1, next_cover);
        solve(half, x, y+half, missing_x, missing_y, next_cover);
        solve(half, x+half, y, x+half, y+half-1, next_cover);
        solve(half, x+half, y+half, center_x+1, center_y+1, next_cover);
    }
    // 左下子棋盘
    else if (missing_x > center_x && missing_y <= center_y) {
        chessboard[center_x][center_y] = chessboard[center_x][center_y+1] = chessboard[center_x+1][center_y+1] = cover;
        solve(half, x, y, x+half-1, y+half-1, next_cover);
        solve(half, x, y+half, x+half-1, y+half, next_cover);
        solve(half, x+half, y, missing_x, missing_y, next_cover);
        solve(half, x+half, y+half, center_x+1, center_y+1, next_cover);
    }
    // 右下子棋盘
    else {
        chessboard[center_x][center_y] = chessboard[center_x][center_y+1] = chessboard[center_x+1][center_y] = cover;
        solve(half, x, y, x+half-1, y+half-1, next_cover);
        solve(half, x, y+half, x+half-1, y+half, next_cover);
        solve(half, x+half, y, x+half, y+half-1, next_cover);
        solve(half, x+half, y+half, missing_x, missing_y, next_cover);
    }
}

int main() {
    int size, missing_x, missing_y;
    printf("请输入棋盘大小和残缺格子的坐标：");
    scanf("%d %d %d", &size, &missing_x, &missing_y);
    chessboard[missing_x][missing_y] = -1;
    solve(size, 0, 0, missing_x, missing_y, 0);
    printf("每个格子上的编号如下：\n");
    for (int i = 0; i < size; i++) {
        for (int j = 0; j < size; j++) {
            printf("%4d ", chessboard[i][j]);
        }
        printf("\n");
    }
    return 0;
}

运行程序时，输入棋盘大小和残缺格子的坐标，程序会输出每个格子上的编号，其中-1表示残缺的格子，其余的数字表示3格板的编号。
