Hi everyone! On behalf of the VNOI CUP 2023 team, I would like to invite you to participate in VNOI CUP 2023 Final — online mirror, which will be held in parallel with the official onsite division and the open onsite division.
Some important information about the round:
- Online mirror link.
- Time: Saturday, 22 July 2023, 03:00 UTC.
- Duration: 5 hours.
- Problems: 7 to 10, sorted by difficulty (hopefully!). Each problem contains multiple subtasks.
- Penalty format: AtCoder style, i.e. timestamp of last submission that increased your score + 5 minutes per submission before the best submission for each problem.
To get a flavor of our problems, we recommend you checking out this year's qualifier rounds in the following links: Round 1, Round 2, and Round 3. You can also check out last year's final round online mirror here.

As a person who cannot do any Kuroni's semi-hard problems, I strongly believe that this round is gonna be biblical, and a random Red kid will AC the entire thing in 2 hours!!
so true bestie!!!!
Which Red kid in your opinion will absolutely demolish this round sir? (my humble guess would be thenymphsofdelphi, but of course it could be inaccurate due to signed integer overflow)
Can't really give you a prediction since I don't want to impose a bias, but I'm sure as heck if someone AK in 2 hours I will be very sad :(
orz must participate this
As a tester, I did not test this.
Only tested the previous round.
OMG! It's tomorrow!!!!
