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
0 1 2 3 4 5
 

Sample Output
no no yes no no no
 

ac代码:

#include <iostream>
#include <cstdio>
using namespace std;
int main(){
 int n;
 while(~scanf("%d",&n)){
   if((n-2)%4==0)
       printf("yes\n");
   else
       printf("no\n");
 }
  return 0;
