Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as interview prep, company training, university coursework, practice problems, a speed contest, or to challenge each other.
The first puzzles will unlock on December 1st at midnight EST (UTC-5).
Some changes starting this year from the previous year(s):
There will be 12 puzzles instead of 25. (Why did the number of days per event change?)
There is no global leaderboard. (What happened to the global leaderboard?)








Are you one of the problem setters for AOC?
I am not. The problems are always prepared by Eric Wastl (the creator of AoC).
You can find more about who are involved in the Credits section of the About page.
why cant we have nice things because of toxic competition
Also 12 days is understandable, but I don't understand why its 1 to 12, instead of 13 to 25, most people have breaks in the latter half of December and exams in the first half
This has been answered in the link I posted.
Previously it was 25 puzzles, one each day during Dec 1-25. I think not having it consecutively on Dec 1-12 would confuse some people.
are there any certifications or anything as such?
Nope. There is no competition. It's just for fun.
It's especially fun for non-CPers. They get exposed to stuff like recursion, stack/queue, graph/tree, dynamic programming, bitwise operations.
that's a cool initiative. goodluck

Somewhat of a shame that there is no global leaderboard this year. Hopefully we can have on next year. :(
The global leaderboard only tracks the top 100 participants to get the first and both the gold stars on each day. It becomes meaningless when most of the participants in that list cheat using LLMs. I think it was a good decision. Fewer online competitions should hold potential to be added to a resume. Deters away the grifters.
