Unofficial AtCoder Translations on GitHub
By ADJA, history, 5 years ago, In English

Hello, hope you all are well and doing fine!

Recently, I've been solving some old AtCoder problems that are only available in Japanese (with Google Translate and a lot of guessing). Problems are really nice, so I decided to put short English translations of them on GitHub. Nothing fancy, just several sentences describing the core part of each problem. There are 10 translated problems so far:

https://github.com/ADJA/AtCoderTranslations

(current problems are in the 2100–2400 difficulty range)

Contribute?

How you can help: There are ~382 untranslated problems from the early AtCoder Beginner and Regular contests left, so I encourage you all to contribute! No Japanese required.

It takes about 5-10 minutes for each problem (please solve the problem first if you don't speak Japanese), and can be done right from the GitHub web interface.

Please see contributing section in the README for more information: https://github.com/ADJA/AtCoderTranslations#contribute

I think with enough contributors, all problems can be translated just in several weeks. Plus, solving the problems is a good training too. Isn't that a time well spent in the quarantine? :)

Note that those old problems are not well-organized (prepared without admins), so the quality of problems depend on writers. Some of them are good, others are bad.

The best ones were already translated and used in Open Cup. Does anyone have those statements?

    There are some unusual problems there too. For example this one (translation) gives you all the tests and test generator right away.

    If anybody has Opencup or other translations of old problems, I'd be happy to include them in the repository too.

thanks ADJA a nice thing to do, atcoder problems are really cool. I'm willing to pay if someone wants to help. It's hard to understand those old problem statements from google translate alone.
