This repository holds learning code, not a library or a service. There are no releases; only the main branch is maintained. Nothing here is meant to process untrusted input in production.

If you find something that could harm a person who runs the code, for example a script that writes outside the repository or runs a command it should not, report it privately through GitHub's private vulnerability reporting. Please do not open a public issue for it.

Wrong answers, crashes and slow solutions are ordinary bugs: open a wrong answer report instead.
