HDU 5832 A water problem

Problem Description

Two planets named Haha and Xixi in the universe and they were created with the universe beginning.

There is  73  days in Xixi a year and  137  days in Haha a year. 

Now you know the days  N  after Big Bang, you need to answer whether it is the first day in a year about the two planets.

 

Input

There are several test cases(about  5  huge test cases).

For each test, we have a line with an only integer  N(0≤N) , the length of  N  is up to  10000000 .

 

Output

For the i-th test case, output Case #i: , then output "YES" or "NO" for the answer.

 

Sample Input

  
  

   
   10001
0
333
  
  

 

Sample Output

  
  

   
   Case #1: YES
Case #2: YES
Case #3: NO
  
  

一道水题，问一个数能不能被73和137同时整除，数字很长，用字符串读入。
