Daily Coding
Solve the day's algorithm task with one graded submission
Daily Coding releases one coding task at midnight UTC, the same for everyone, rotating through easy, medium and hard. You write a solution in the browser, test it as often as you like, then submit once. That single submission passes or fails, and it settles the day.

About Daily Coding
The tasks cover algorithms and data structures, such as coin change. It suits people who want a short, high-stakes daily problem rather than a big problem bank.
Reading the task and running tests needs no account. A free account is needed to submit, and it adds streaks, points, levels, badges and leaderboards. It supports eleven languages, has no ads and is open source.
