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.
