Re: 207 - PGA Tour Prize Money

I think the uDebug code is still slightly off when it comes to printing prize amount, at least based on my reading of the statement (there's a difference between winning $0.00 and not winning anything IMHO). Which I guess means the judge data is also a bit lacking since my AC code disagrees on this ...

Re: 12734 - Guess the String

It seems like the judge for this problem is broken? Can someone check it please?

Perhaps submission for this problem should be disabled until it can be fixed.

Re: 10069 - Distinct Subsequences

To clarify, the reason big int is required is because the statement is supposed to say 10^100, not 10100

Also the description of "subsequence" is cribbed directly & without credit from Intro to Algorithms, which is shameful to say the least.

Re: 12287 - Network Flow

It seems to me there's something wrong with the data for this problem. Ignoring the part about optimizing the rotation in the flow, I'm having difficulty understanding how to justify the TRA computation used to get ACC (which I just got). Consider the following cases, which all specify the same pump...

Re: 10840 - Multi-stage Compressor

Thanks to uDebug I finally got AC on this problem. There is a discrepancy between the data and problem statement. The statement says to output p_i, but actually what works is to output p_i / p_1. In other words we want not the output pressure after stage i but the compression ratio after stage i. Th...

Re: 597 broken input

I know I can't get AC. I thought I read somewhere that red checkmarks could mean no I/O or could mean the OJ has input but not a verified output. Not that I could find anywhere that explains what the checkmarks mean (do you have a link for that?) Anyway, the judge is definitely providing non-empty i...

511 Sample output erroneous

It seems the issue mentioned in the forum thread:

http://acm.uva.es/board/viewtopic.php?f=6&t=42698

has not been addressed (probably it wasn't reported directly?).

Please take a look.

Thanks!

597 broken input

I realise this problem has a red checkmark (I didn't at first since I accessed it via http://uva.onlinejudge.org/external/5/597.html directly), but it seems the input doesn't follow the specification (giving me runtime errors until I figured out the problem). I confirmed there aren't any empty lines...

Re: 10679-I Love String!!! - Shallow judge data

Has this been fixed? I don't want to submit to find out since it would surely overwrite my current (legitimate) ranking. I couldn't find any post by Carlos noting that this issue was addressed.

Slow judge

I haven't submitted to this judge in a while, but it seems excessively slow. Is it related to a brief downtime earlier today? Or perhaps someone ("Lee Wei") making a huge number of submissions over a short period?

Careful Igor -- unless the two points are a full diameter apart, they actually determine two circles with a given radius (or none, if they are further apart than a diameter), not a unique one.

You could also make your queue variable local to the while loop, since that seems to be the only place you use it.

I agree. Your vm.push_back(m) in particular -- you're making a copy of the dictionary so far and pushing it into the vector...so at the end you end up with a vector with O(n^2) string pairs inside...

Sorry, you're not even close.... Why do you assume "k" has to be an integer? There is no reason that k^2-4uk-4 should be a perfect square, you only need it to be positive. If this is homework, have you done Lagrange multipliers? Or any calculus at all?? I can tell you that you'll probably need a der...
