A timed contest where all contestants compete online and are given the same problems to solve under the same time constraints.
The Development Competition includes the following tracks: Code, Assembly, and Architecture.
The F2F Competition asks competitors to perform small fixes to challenge results or to actually fix bugs.
Marathon Competition offers a longer timeline, and an opportunity for competitors to iterate and improve their solutions against open-ended problems that have no single right answer.
