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.
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
