 » 4 years ago, # |   -10 What is wrong with sample test case in problem Platinum Problem 2. Exercise Route??I think bad data...Your output file exercise.out: [File missing!]The correct answer: 13223522111
•  » » 4 years ago, # ^ | ← Rev. 2 →   0 The answer for sample is 4 according to the sample:SAMPLE OUTPUT:4
•  » » 4 years ago, # ^ | ← Rev. 2 →   0 I printed n and m and it said that they are equal to 1000 and 200000.
•  » » » 4 years ago, # ^ |   -41 Please do not discuss the problem as the contest is still running. Thank you.
•  » » » » 4 years ago, # ^ | ← Rev. 2 →   -10 I do not actually discuss the problem.I mentioned something from the statement or gave ideas?
•  » » 4 years ago, # ^ |   +30 Thanks for pointing this out; the issue was that the sample case was not the first test case. This is being fixed and past submissions are being regraded.
 » 4 years ago, # |   -50 Is anyone taking silver?

•  » » » 4 years ago, # ^ |   -45 LOL I just wanted to know who's taking silver.
•  » » » » 4 years ago, # ^ |   +47 LOL I just said that sample is wrong.
•  » » » » » 4 years ago, # ^ |   +34 Okay okay I'm sorry. :P
 » 4 years ago, # |   +33 All problems are FFT in every division. Change my mind.
•  » » 4 years ago, # ^ |   0 Actually the time limit for Java allows slow fourier transform too.
 » 4 years ago, # | ← Rev. 4 →   +6 I think there's something wrong with the test data of Gold P2, can someone who got AC on that reply to this comment.UPD: The test data was indeed wrong and the submissions were rejudged.
•  » » 4 years ago, # ^ | ← Rev. 2 →   -11 I wouldn't consider this cheating but you're walking a fine line so I'd be careful. Anyways, I hope you get your problem solved!EDIT: Glad the test cases were fixed.
•  » » 4 years ago, # ^ | ← Rev. 4 →   0 Wait there was something wrong with the Gold Problem 2 test data? I thought it was only platinum problem 2? Also, who announced that the test data was wrong and when was it rejudged?Edit: Noobita answered my question already: it was early on in the competition and the grading machine had trouble with whitespace. Thanks again Noobita.
 » 4 years ago, # |   +8 Wouldn't the fact that the contest is open the entire weekend allow for cheating if you create a fake account and read the problems and then once you solve them confidently log into your main and start the test? How does USACO deal with this?
•  » » 4 years ago, # ^ | ← Rev. 2 →   +14 Perhaps the US competitors must do the test in a certain hour or under the supervision of someone. Coordinators trusting in their competitors is a risky bet (perhaps unfair for honest participants)
•  » » » 4 years ago, # ^ |   0 US competitors take the exam the same way everybody else does. There aren't any special procedures.
•  » » » » 4 years ago, # ^ |   0 My perfect world idea is that competitors which can solve the problems obtaining the required score in a weekend, are sufficiently proud of themselves for cheating.
 » 4 years ago, # |   -47 wait wut problem one on silver is sooo hard!
