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
