triomino拼图c语言

好的，以下是Triomino拼图的C语言代码：

#include <stdio.h>
#include <stdbool.h>

#define SIZE 3

void TrominoTile(int x_board, int y_board, int x_missing, int y_missing, int size_board, int board[SIZE][SIZE]) {
    int x_center, y_center, count;
    if (size_board == 1) {
        return;
    }
    count = 0;
    x_center = x_board + size_board / 2;
    y_center = y_board + size_board / 2;
    if (x_missing < x_center && y_missing < y_center) {
        count++;
        board[x_center - 1][y_center] = count;
        board[x_center][y_center - 1] = count;
        board[x_center][y_center] = count;
        TrominoTile(x_board, y_board, x_missing, y_missing, size_board / 2, board);
        TrominoTile(x_board, y_center, x_center - 1, y_center, size_board / 2, board);
        TrominoTile(x_center, y_board, x_center, y_center - 1, size_board / 2, board);
        TrominoTile(x_center, y_center, x_center, y_center, size_board / 2, board);
    } else if (x_missing < x_center && y_missing >= y_center) {
        count++;
        board[x_center - 1][y_center - 1] = count;
        board[x_center][y_center - 1] = count;
        board[x_center][y_center] = count;
        TrominoTile(x_board, y_board, x_center - 1, y_center - 1, size_board / 2, board);
        TrominoTile(x_board, y_center, x_missing, y_missing, size_board / 2, board);
        TrominoTile(x_center, y_board, x_center, y_center - 1, size_board / 2, board);
        TrominoTile(x_center, y_center, x_center, y_center, size_board / 2, board);
    } else if (x_missing >= x_center && y_missing < y_center) {
        count++;
        board[x_center - 1][y_center - 1] = count;
        board[x_center - 1][y_center] = count;
        board[x_center][y_center] = count;
        TrominoTile(x_board, y_board, x_center - 1, y_center - 1, size_board / 2, board);
        TrominoTile(x_board, y_center, x_center - 1, y_center, size_board / 2, board);
        TrominoTile(x_center, y_board, x_missing, y_missing, size_board / 2, board);
        TrominoTile(x_center, y_center, x_center, y_center, size_board / 2, board);
    } else { // (x_missing >= x_center && y_missing >= y_center)
        count++;
        board[x_center - 1][y_center - 1] = count;
        board[x_center][y_center - 1] = count;
        board[x_center - 1][y_center] = count;
        TrominoTile(x_board, y_board, x_center - 1, y_center - 1, size_board / 2, board);
        TrominoTile(x_board, y_center, x_center - 1, y_center, size_board / 2, board);
        TrominoTile(x_center, y_board, x_center, y_center - 1, size_board / 2, board);
        TrominoTile(x_center, y_center, x_missing, y_missing, size_board / 2, board);
    }
}

void PrintBoard(int board[SIZE][SIZE]) {
    for (int i = 0; i < SIZE; i++) {
        for (int j = 0; j < SIZE; j++) {
            printf("%2d ", board[i][j]);
        }
        printf("\n");
    }
}

int main() {
    int board[SIZE][SIZE] = {{0}};
    int x_missing, y_missing;
    printf("请输入缺失方块的坐标（x, y）：");
    scanf("%d%d", &x_missing, &y_missing);
    board[x_missing][y_missing] = -1; // 标记缺失方块
    TrominoTile(0, 0, x_missing, y_missing, SIZE, board);
    printf("Triomino拼图如下：\n");
    PrintBoard(board);
    return 0;
}

在代码中，先定义了一个`TrominoTile`函数，用于填充拼图。其中，`x_board`和`y_board`表示当前矩阵的左上角坐标，`size_board`表示当前矩阵的大小，`x_missing`和`y_missing`表示缺失方块的坐标。当`size_board`等于1时，表示只有一个方块，直接返回；否则，根据缺失方块所在的象限，将矩阵分为四个子矩阵，递归调用`TrominoTile`函数进行填充。

在`main`函数中，先将缺失方块的位置标记为-1，然后调用`TrominoTile`函数进行填充。最后，调用`PrintBoard`函数打印填充后的矩阵。

希望能够帮到你！
