Happy New Year to the Codeforces community!
I would like to invite you all to join the mirror of the Ateneo Senior High School Programming Varsity's mid-year contest, Dagitab 2021. You will be given a little under 10 days to solve 13 problems. The problems will be available starting 9:00 am on Jan 2 (UTC+8), and the contest officially runs until 11:59 pm on Jan 11 (again, UTC+8).
EDIT: The problems are now available. Good luck!

Most of the problems in the contest are standard, since it is targeted at beginners, so as long-format, I think this contest would be educational for people up to Cyan level. More experienced contestants could even treat these 13 problems as an easy ICPC set, and a team of three Purples could possibly finish the entire set within the 5-hour period (I think).
I also guaranteed that all these problems are comfortably solvable using Python (though you might need to submit to PyPy or still use fast I/O for some of them).
Regardless, I think the problems should be relatively interesting, and I'm quite proud of my work, so please check it out :D It will be fun!
Thanks to my friends dsjong, jvafable, hexagonforce, daniddelrio, and csfromcs for testing the problems. Thanks also to verngutz and PPTGamer for helping me in the writing process and reading over the final problems. Thanks also to kevinsogo whose KompGen library was invaluable in creating the test data for all these problems. And of course, thanks to MikeMirzayanov for Codeforces and the Polygon platform.
The problem stories revolve around the various adventures of ProgVar students Alice, Bob, and Cindy. Here's some art of Alice that I commissioned my wonderful friend @saji_tan (https://twitter.com/saji_tan) to do for me. Three of the problems have some chibi art of Alice in them! Maybe next year I can afford art for Bob and Cindy...
We hope to see you in Dagitab 2021!
