思路

1.主要时判断行列的范围是否有效

Answer

#include<stdio.h>
void initexcel(int m,int n){//初始化表格
    if(m>9||n>9)
         printf("-1\n");
    else
        printf("0\n");
}
void change(int m,int n,int x1,int y1,int x2,int y2){//交换
    if(x1<0||x2<0||y1<0||y2<0)
        printf("-1\n");
    else if(x1>=m||x2>=m||y1>=n||y2>=n)
        printf("-1\n");
    else
        printf("0\n");
}

    if(m+1>9||x>=m)
        printf("-1\n");
    else
        printf("0\n");
}

    if(n+1>9||y>=n)
        printf("-1\n");
    else
