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
   
   
   
   

import java.util.Scanner;

class Main{
    public static void main(String[] args) {
        Scanner input=new Scanner(System.in);
        while (input.hasNext()){
        	int n=input.nextInt();
        	int arr[]={1,2,0,2,2,1,0,1};
        	if (arr[n%8]==0){
        		System.out.println("yes");
        	}else {
        		System.out.println("no");
        	}
        }
    }
