I'm getting WA too, and I was accepted in SPOJ in this fairly moment... So I'm asking for the judges to fix this as soon as possible... thx

Well, we improved a lot since that update, but still I get WA on case 16, so any help on this would be appreciated...

It gives -89, cos the distance between two points is the euclidean distance "rounded up", so sqrt(2)=2, anyway I want to ask the judges to check if the official solution runs in time, please, thnx...

Please admins, check the datatests for this problem, it has been giving Presentation Error for many users for a long time with no reason (I tried it myself, even with an already accepted solution)...

I did, yeah... After fixing a little mistake in the order of the answers...

hahahha, ok, I'm now waiting for a friend to implement his solution and then check it down with mine...

Yeah, but anyway I thought there should be problems where float is enough, well, it seems I was wrong...

Hey, now I got accepted, it was my suspicion long time ago, and now the mistery looks clearer, it seems our COJ has problems working with float numbers, because the only thing I changed was the float by double....

Hey, does anybody knows the meaning of "If two sections apply to the same vertex, then you must take the section with the lowest index.", I don't see a way in which this can occur, and that's probably why I'm getting WA, thanks in advance...

Hey, I was just trying to solve this problem, and got wrong answer, then I got the official solution, and saw it did gave the same result, WA, so are we sure, that the datatests are alright????
