Hi Codeforces!
We would like to invite you to participate in Codeforces Round 984 (Div. 3) on Nov/02/2024 17:35 (Moscow time). You will be given 7 or 8 problems and 2 hours and 15 minutes to solve them. The penalty for an incorrect submission will be 10 minutes. There may be interactive problems in the round.
The round will be ruled according to the standards of educational rounds (extended ICPC). Thus, solutions will be judged on preliminary tests during the round, and after the round, there will be a 12-hour phase of open hacks. After open hacks all accepted solutions will be rejudged on successful hacks. We've tried to make decent tests — just like you, we'll be upset if you have dropped solutions after the end of the contest.
Reminder that only trusted Division 3 competitors will be included in the official results table. This is a forced measure to combat unsportsmanlike behavior. To qualify as a trusted Division 3 competitor, one must:
- participate in at least five rating rounds (and solve at least one problem in each of them)
- not have a point 1900 or higher in the rating.
Whether you are a trusted Division 3 participant or not, if your rating is less than 1600, the round for you will be rated.
The tasks were authored and prepared by a team consisting of Seny, eugenechka.boyko.2_0-0 and myself.
The round is based on the recent Lipetsk Team Programming Olympiad for school students. Please note that if you are a participant of the Olympiad, you are not allowed to participate in this round. Thanks to the coordinator of this Olympiad myav and the author Small_machine, whose tasks were not included in this round due to their high complexity.
We thank very much:
- Vladosiya for excellent coordination
- Sokol080808, FBI, ssor96, itz_pabloo, IceHydra, justlm for testing the round
- MikeMirzayanov for creating the wonderful Codeforces and Polygon platforms.
- You for participating!
Looking forward to Round 984. Let’s have a good contest. Good luck, everyone!
As a tester i almost became a tester and I am happy about it.
As a non-tester, I did not test it.
as a tester, i can assure you that these problems are, indeed, problems!
As a !tester I think you will like the problem sets
Even though I will be considered a trusted participant, when I'm trying to register, it says, "You are registering "out of competition" reason: rating should be between 0 and 1,599 in order to register for the contest." Why is it so?
your rating is $$$\ge 1600$$$, so you are an unrated participant
Then what about the trusted participant thing mentioned in 3rd paragraph? More than 5 contests and <1900
About the results table of the round.
The max rating not at 1900 or higher imo is to cross out the scenario that someone already participated a lot and had a high skill ceiling that purposely threw their ratings down to oblivion just to be rated in Div3/Div4.
In short, preventing smurfing from legit/long-reputated account.
But in fact, unrated participation is a way to increase your rating on your second accounts. So, we already have a lot of cheaters.
True. Honestly those measures hold more to the moral ground than actual enforcement. That's something, but not perfect.
I pray that we will not have an unrated parc. in div2/div1.
But we can do something like you can't create more than 1/2 accounts from 1 mac-adress.
that will be cool
as a tester, i want to sleep, i hope you enjoy the tasks
hope to enjoy this round
we hope so too:D
what is the difference between div1, div2 and div3? Is it only the level of difficulty?
Yes, div1 is the hardest, div2 is slightly easier (often, div 2 contests run in conjunction with div1 contests, where the div 1 contest starts with the div 2 C problem), then div 3 is easier (I'd say div 3 E is equal to div 2 C in a lot of cases), then div 4 contests (which aren't as common) are the easiest
Finally! An adequate round without pendochinese aithors!
With love to my kittens
