Hi everyone,
I am currently participating in the gym contest CCPC 2016-2017, Finals (http://mirror.codeforces.com/gym/101206). It appears that there may be a problem with test data for problem L, but I don't know how to fix it.
My team felt that something may have gone wrong when we noticed that most ghost participants had solved the problem, but none of the live competitors managed to solve it. My team's code failed on test 1, which is usually sample data, but it passes on local tests and on custom invocation.
After enabling coach mode in gym, I found that there was a mistake in test 1 of problem L, and it looks like the sample test case was miscopied. Unfortunately I don't know how to fix this issue, and I could only notify competing teams that there was an issue.
If you have the time and know how to work with Polygon, can you please change the test case to match the problem data?
Thanks.

PS: I'm not sure if I was supposed to enable coach mode in this situation, but I hope that it was the right decision.
I have fixed it and rejudged all the submissions. I am very sorry for the wrong data.
No need to be sorry, preparing a contest is a lot of hard work. Thanks for the time you spent in preparing the gym!
mathlover What is happening with problem F? We are receiving Denial of judgement verdict on any code we submit.

I have rejudged your submissions at coach mode. And they run as usual. I think you meet a corner case about Codeforces judgement system.
