One challenge per day, and it is the same challenge for everyone. Borrowed from Advent of Code, except it runs all year instead of twelve days in December.
You solve it in the browser in one of 11 languages (JavaScript, TypeScript, Python, PHP, Ruby, Java, Go, C++, C#, Rust, Swift), and the tests run in a self-hosted Piston sandbox in well under a second. Once you submit, every other solution to the same challenge becomes readable.
No account needed for today's challenge. Free, non-commercial, open source under MIT, including the sandbox setup. 40 challenges so far, so the rotation repeats after 40 days until I write more.
