The end of the December is fast approaching and it is time for the
best last contest of the year! The Good Bye 2018 round will take place on Sunday, December 30, 2018 at 14:35 UTC.
As the people who already engaged in discussions about the ultimate problem suspect, I am the problem writer. As such, I'd like to thank to:
- arsijo and KAN for the round coordination and one of the problems,
- AlexFetisov, cyand1317, Errichto, Jeel_Vaishnav, Lewin, misof, winger for testing and invaluable suggestions,
- MikeMirzayanov and everyone involved in building and running Codeforces and Polygon platform.
The round will last for 2:30 hours and you will be given 8 problems for both divisions. There will be an interactive problem.
You have the last opportunity to reach Your rating goals for 2018. Good luck!
UPD: The top 3 participants eligible for ICPC 2019/20 season can win a great prize.
UPD2: The scoring distribution is 500-1000-1750-2250-3000-3000-3750-4000.
UPD3: Round is finished. I hope you enjoyed the contest! I am really sorry for the duck-up in problem G. I'll share more details once the important things (systest, editorial ...) are taken care of. The systest might be slightly delayed because of that.
UPD5: We apologize for the issue with problem G. We are still investigating this issue. Verdicts “Idleness limit exceeded” may be changed to other. We will write a full report about it later.
UPD6: The results are final, rating will be recalculated shortly. Congratulations to the winners:
