Re: IOI 2008 (response to post by mugurelionut) | Reply
Yes, my submissions disappeared, too, now they are visible again and I can see the results of my submissions when I click on them.
Re: IOI 2008 (response to post by mugurelionut) | Reply
My submissions disappeared in 30 minutes after contest end.
And I had result 3-4 hours later.

Well, my submissions disappeared, too.
However is it possible to access the test data used?
I've got lots of runtime errors (SIGABRT), and can't understand why.
I'd like to test locally to replicate the error, hence understanding how to avoid it next time.

My submission disappeared, so I don't remember for sure the test cases I'd need, but I think one was 6bpf from fish.

The task PRINTER was really easy. My program passed it in online contest
with only sorting. The main part of the problem is to write a comparision
function for sorting, which is easy enough. I think there will be many
100 scores on that problem.

You mean like:

sort( v.begin(), v.end() );

Yeah, that was really the hardest part.

Experimenting a bit (and checking my code with -Wall), I've found out that I had lots of warnings such as doing
long long tmp;
scanf("%d", &tmp);

Could this be the cause of SIGABRTs (on some cases)?

Yes, I've read it, but actually I can't really understand why I got so much troubles with the online judge.
On my computer it always worked (the error might be appearing with slightly bigger inputs), but lots of test cases failed for this reason.
I'd like to avoid this on today's competition. :P
