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 NN 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 55 huge test cases).
For each test, we have a line with an only integer N(0≤N)N(0≤N), the length of NN 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
A water problem题目·很明确,一道水题.但抱歉的是高精度取余我懂,所以经不断的哇.10^10000000的数,所以是一定要用高精度取余的.
