韩信点兵

#include <iostream>#include <cstdio>int main(){   freopen("in.txt","r",stdin);   freopen("out.txt","w",stdout);   int x,y,z,i;   while(scanf("%d%d%d",&x,&y,&z)==3)   {           for(i=10;i<=100;i++)           {                if(((i-x)%3==0)&&((i-y)%5==0)&&((i-z)%7==0))                {                    printf("%d",i);                    break;                }           }           if(i>100)             printf("No answer\n");   }    return 0;}

还是人太笨，大一总是没理解题意
