Kata

Somebody adopt this -- "This user has deleted their profile"

Returning inconsistent data types is not a best practice.

If you don't want an Error thrown when no integers are found, I guess returning undefined is the least of the other evils in this case.

Hi, thanks for your comment. I wrote this Kata as an 8 kyu starter question for absolute beginners. It was similar, in my opinion, in its complexity and difficulty to the question I received when I joined the site. Thanks for letting me know it is similar to another Kata. I've unpublished it and I'll build on it from here.

It is apparent from the shockingly low quality of this Kata that the Kata author has put in no effort whatsoever to even attempt to make this Kata remotely presentable to the Community. I would suggest that you unpublish this Kata and coming up with a much better idea before publishing a new Kata.

A watered-down duplicate of this 8 kyu Kata. This means that this Kata fails to present novel content to the user undertaking it. The lack of novel content in a Kata as an Issue is recognised as an official CW stance.

Your Kata needs more extensive test coverage to prevent easy cheap-cheat solutions and/or logically flawed solutions. The most common way to increase test coverage is through the inclusion of randomly generated test cases at runtime so please add these. The lack of test coverage in a Kata as an Issue is recognised as an official CW stance.
