思路:(10*a+b)%c=((a%c)*10+b)%c;

 

#include<iostream>
using namespace std;
const int mm=100010;
char s[mm],ss[mm];
int main()
{ int ans,anss;
while(cin>>s>>ss)
{
ans=anss=0;
for(int i=0;s[i]!='\0';i++)
{
ans=(ans*10+s[i]-'0')%86;
}
for(int i=0;ss[i]!='\0';i++)
anss=(anss*10+ss[i]-'0')%86;
ans=(ans+anss)%86;
if(ans)cout<<"no\n";
else cout<<"yes\n";
}
}
