How to Ask
Is your question a programming puzzle or code golf challenge?
All challenge questions on this site should have:
- A clear specification of what constitutes a correct submission, so that it is possible to indisputably decide whether an entry is valid or not. Test cases are highly encouraged.
- An objective primary winning criterion, so that it is possible to indisputably decide which entry should win.
Please follow a standard template and post first in the meta Sandbox for feedback.
If your question is about this website, ask it on meta instead.
