            it = mp.find(num);
            if(it != mp.end()){
                if(people != 0 && thispeople == 0) printf("\n"); //所有违禁人数
                if(thispeople == 0) printf("%s:",name);
                printf(" %04d",num);
                thispeople++;
                thisflag = 1;}

        
        }
        if(thisflag == 1) people++;
        thing += thispeople;}

    if(people != 0) printf("\n");
    printf("%d %d",people,thing);
    
    return 0;
}

一个小小的注意事项，printf(" %04d",num)，你看看这个04，是不是你苦苦追寻的那个测试点2
