找到包含相同数字序列的列和行的索引

Question

我想找到2D数组中包含相同数字序列的列和行的索引。 例如

{2, 3, 2, 6} 
{3, 6, 3, 10} 
{7, 4, 2, 12}
{6, 8, 6, 4}

在此示例中，程序必须返回行索引0和列索引2 我用C语言编写了一个程序，但是没有用

# include <stdio.h>
        int main(){
            char tab[3][3];
            int simiLgn, simiClm;
        for (int i = 0; i<3; i++){
            for (int j = 0; j<3; j++){
                printf("Tableau[%d][%d]=", i, j);
                scanf("%d", &tab[i][j]); 
            }
        }

        for (int i = 0; i<3; i++){
            for (int j = 0; j<3; j++){
                printf("%d \t", tab[i][j]); 
            }
            printf("\n");
        }


        int fix_lgn = 0;
        int fix_col = 0;
        while (fix_lgn<3){
            while (fix_col<3){
                for (int i=0, j=0; i<3, j<3 ; i++, j++){
                    if(tab[fix_lgn][j] == tab[i][fix_col]){
                        simiLgn = fix_lgn;
                        simiClm = fix_col;
                    }
                    else{
                        simiLgn = -1;
                        simiClm = -1;
                    }
                }
                fix_col++;

        }
        fix_col = 0;
        fix_lgn++;
        }

        printf("ligne index: %d\n", simiLgn);
        printf("colonne index: %d\n", simiClm);

        return 0;
    }

谢谢
