hi, Im yoshiro.

sorry, my problem was I sent an old version of my program to the judge by accident.

The program that passed millions of test cases of course got AC. I enjoyed writing that test case generator : )!!

I posted several critical test cases for this program challenge here, but I don't see them here any more.

I will look again. If I find them I will post here.

have a good day,
-yoshiro (mark) aoki

The test cases I posted were in my post right before yours.

I see that my message there has been cut away (removed).

Maybe my posting of that information was not allowed

Ok, from memory I can offer only small advice, and that is to be sure to write test cases to check border conditions.

Hope that helps. Now, I must get back to working

what is the exact input limit for this problem??

my solution works well for <100000000;

but does nt wrk more than that.

can anyone help???

here is my code.

is I/O format ok???

i got TLE;
but why??????

You can't read, or what?

The problem statement is very specific about what you should expect in the input:

Looks good to me.

Because your program can't solve 11000 test cases in under 3 seconds.

You need to solve each test case much faster, than with a loop with many millions of iterations.

LOts of people give input/output for num>=100000000.
which needn't to be cosidered because problem statement says

The input will contain one or more line each containing a positive integer N (N<100000000).

You can simply solve this using brute force. May be there is a smarter way to get lower runtime but I am too lazy to figure it out as I got Accepted. My code got Accepted in 0.572(not a good runtime but whatever). Just use a character array to precalculate and print the N-th(or (N-1)-th, depending on what you use) index of the array.
