How Codettas Work

Small code-golf like challenges

Codettas are small F-flat-minor code-golf like challenges with fixed expected output. Many mirror code.golf holes, with a few repo-defined variants.

Leaderboard rank is based on optimized compiled .ffb byte count, not source length. Output has to match the expected result before the byte score matters.
