@manuhdez Great. It makes much more sense now. Thanks for the PR. 👍
@raisedadead Can we merge this?

Hi @manuhdez first of all thanks a lot for taking the time to make this pull request.

However I am of the opinion that changing the title does not resolve the issue that the OP on the original thread as mentioned.

Please continue on the original thread. We will guide further on a proper update to the challenge, post which you can update this request.
