第一期8.This problem is also a A + B problem,but it has a little difference,you should determine does (a+b) could be divided with 86.For example ,if (A+B)=98,you should output no for result.

#include<iostream>
using namespace std;
int main()
{
    int a,b;
    while(cin>>a>>b)
    {
    if ((a + b) % 86 == 0)
        cout << "yes"<<endl;
    else
        cout << "no"<<endl;
    }
return 0;
}
