Fibonacci Again (簡單規律題)

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
