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
The answer for sample is 4 according to the sample:
SAMPLE OUTPUT:
4
I printed n and m and it said that they are equal to 1000 and 200000.
Please do not discuss the problem as the contest is still running. Thank you.
I do not actually discuss the problem.
I mentioned something from the statement or gave ideas?
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.
Is anyone taking silver?
Please do not discuss the problem as the contest is still running. Thank you.
LOL I just wanted to know who's taking silver.
LOL I just said that sample is wrong.
Okay okay I'm sorry. :P
All problems are FFT in every division. Change my mind.
Actually the time limit for Java allows slow fourier transform too.
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.
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.
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.
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?
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)
US competitors take the exam the same way everybody else does. There aren't any special procedures.
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.
