Hi everyone,
April Fools is near and as usual we have an April Fools Day Contest on Codeforces this year. In addition to that, I usually try to host some form of mini April Fools Contest for my friends every year (or almost every year).
This year, I am trying to host a bigger April Fools Day contest than usual and I invite everyone to participate! In view of the April Fools contest on Codeforces, the round will begin at 31 March 10pm (GMT+8) and lasts for exactly $$$24$$$ hours (and thus it will end ~35 minutes before the CF April Fools round).
The contest will consist of several unusual tasks, and I hope that everyone will at least find something interesting. The problems will not be sorted by increasing order of difficulty (if the word difficulty is even applicable), so it is highly advisable to read (and try!) all tasks. This round is not an offical Codeforces round and thus is obviously unrated.
There is a Discord server for this contest (you can join it using this link). The Discord server might be required for some tasks. Hope to see you there!
Contest Link: here
UPD: The contest is open to both individuals and teams. However, if you decide to join as part of a team, I encourage you to use the team registration feature on CF or at least submit from just one account.
I would also like to thank gamegame and Savior-of-Cross for their help in testing and feedback (which changed one of the tasks).
The contest scoring will be IOI-styled, and there are no time penalties. Most of the tasks have some form of partial scoring. There will be $$$7$$$ tasks in total, with scores $$$100-100-100-100-100-100-200$$$.
UPD 2: Registration should be open now. The contest starts in ~6 hours. Good luck and have fun! (If you haven't joined the discord server, I encourage you to do so :) ).
