Run the whole suite:

Add a new language:

1. Drop your source under a new folder (keep the pattern <lang>/...).
2. Implement the optimal $O(n)$ hash-map Two Sum and print <Language>: OK after self-checks.
3. Wire the build/run commands into scripts/run_all.sh.
4. Add a job for it in .github/workflows/ci.yml so CI runs it (mirror the simple pattern used by the others).
5. Make sure the GitHub Action still passes.
