Re: PROBLEM STATEMENT CORRECTED bbi5291 soft Aug 24, 2010 - 10:35:45 pm UTC
PROBLEM STATEMENT CORRECTED SourSpinach Some constraints in the problem statement did not match the test rather than changing the test data, I just changed the problem statement. Firstly, now boxen of area 0 are allowed - but the... Aug 24, 2010 - 8:35:53 pm UTC
Re: Re: Is the judge wrong? SourSpinach My only guess is that my program handles boxen with area 0 differently than yours. I'll correct those cases and redo the output. Aug 02, 2010 - 3:21:02 am UTC
Re: Re: Is the judge wrong? ryuuga Cases 8-12 have boxen with 0 area.. easy to check for and filter out cases 8-11 are the 4 I get wrong.. there aren't many special cases, so I can't figure out what they are. All test data laser start... Jul 31, 2010 - 7:01:06 pm UTC
Re: Is the judge wrong? SourSpinach The problem should've specified that x2>x1, and y2>y1 - that's been fixed. As for the data itself, I don't know what I was smoking when I wrote the test case generator, but it does indeed allow for b... Jul 31, 2010 - 4:58:40 pm UTC
Re: sample test case does not satisfy y1<=y2 SourSpinach Yeah, that one box just didn't satisfy that condition - I have no idea what I was doing. It's fixed now, the y coordinates have simply been switched. I don't believe this happens in any of the actual... Jul 31, 2010 - 4:40:51 pm UTC
Is the judge wrong? ryuuga Only 4 of the cases give a WA for me. These are 4 out of the 5 cases where boxes have 0 area( x1==x2 or y1==y2) I don't see why there should be boxes with no area to begin with, but these boxes don't ... Jul 30, 2010 - 7:33:05 pm UTC
sample test case does not satisfy y1<=y2 ryuuga for the first box in sample data, -1 5 1 -1, y1 -1), though it should be. Could cause bugs in programs if it is assumed but not true Jul 30, 2010 - 5:32:22 pm UTC
Hint SourSpinach This is simply a simulation problem - however, it's a particularly nasty one, with many details that could go wrong. Perhaps the trickiest part is finding the box union - after that, simply store it i... Sep 02, 2009 - 9:25:58 pm UTC
