写一段求二维整型数组的鞍点的c语言代码

以下是求二维整型数组鞍点的C语言代码：

#include <stdio.h>

#define ROW 3
#define COLUMN 3

void saddlePoint(int mat[][COLUMN]) {
    int i, j, k;
    bool flag = false;

    for (i = 0; i < ROW; i++) {
        // find the minimum value in row i
        int min = mat[i][0];
        for (j = 1; j < COLUMN; j++) {
            if (min > mat[i][j]) {
                min = mat[i][j];
            }
        }

        // check if the minimum is maximum in its column
        for (k = 0; k < ROW; k++) {
            if (min < mat[k][j]) {
                break;
            }
        }

        // mat[i][j] is a saddle point
        if (k == ROW) {
            printf("Saddle point found at (%d, %d): %d", i, j, mat[i][j]);
            flag = true;
        }
    }

    if (!flag) {
        printf("No saddle point found in the given matrix.");
    }
}

int main() {
    int mat[ROW][COLUMN] = {{2, 3, 4}, {5, 6, 7}, {8, 9, 1}};

    saddlePoint(mat);

    return 0;
}

该代码中用了嵌套循环来遍历每个元素，找到每行的最小值，然后在当前列找到最大值，检查是否存在鞍点。如果存在，则输出其位置和值。如果不存在，则输出找不到鞍点的信息。
