Problem Description
There are another kind of Fibonacci numbers: F(0) = 7, F(1) = 11, F(n) = F(n-1) + F(n-2) (n>=2).
 
Input
Input consists of a sequence of lines, each containing an integer n. (n < 1,000,000).
 
Output
Print the word "yes" if 3 divide evenly into F(n).
Print the word "no" if not.
 
Sample Input
 
Sample Output
#include<iostream>
#include<cstring>
using namespace std;
int main()
{
	int n;
	while(cin>>n)
	{
		if(n==2)   cout<<"yes\n";
		else  if((n-2)%4==0)    cout<<"yes\n";
		else   cout<<"no\n";
	}
	return 0;
}
