Hmm....This problem doesn't seem that hard....except may be a lot of printing. Is there any trick to it that no one has solved it yet?

I see that a good number of people have tried.

Maybe the testcases aren't correct. I don't think the problem is that difficult...
The only thing I can come up with is that there is some trick with the format, although I copy-pasted it and I am getting WA...

I think this problem is impossible to be solved in 3.000 sec, since there is a lot of data to be printed. I did my best and all I got was a TLE. Then, I removed my print statements and got WA in 0.010. So, how can I solve a problem that I can't print the correct output without getting TLE?

It's not strange that no one still solved this problem!

Is there a more fast way to output data?

How can I report that?

P.S.: Sorry for my bad english.

The fastest way to print will be fprintf, if that's not fast enough you can use fwrite. Or, an even better way is to first store the output in a buffer (char array) and use less print statements (since flushing buffer takes time, I think). But I am not an expert at I/O.
