@alxkm Does this kind of contribution qualifies as a meaningful algorithm for this repo? Honestly i think this one-liner is too simple...

[alxkm]

@DenizAltunkapan, yes, I agree - an odd-even checker is quite a standard utility and doesn't really qualify as a meaningful algorithm in the context of this repository.

see comments above -> not considered as meaningful algorithm in this repo

Hi @DenizAltunkapan @alxkm Thank you for the feedback and for clarifying the repository’s focus. I appreciate the guidance on what qualifies as a meaningful algorithm here. I’ll look into contributing more substantial algorithms or data structures that better align with the project’s goals.

If you have any recommendations or suggestions on specific topics or areas that need contributions, I’d be happy to explore those. Thanks again for your time and consideration.
