I was worried about that. Is there a way to limit use of the standard library in a way accepted by the community? I feel like this problem is trivial if you are allowed to use a hash table or vector, but becomes much much harder and a more useful exercise when you have to use pointers. Thanks for the information though!

Thank you for the explanation. I will concede that your points are quite valid as even when I was writing up the solution for this I made a list of pointer variables and forgot to put an astrik in front of the later variables. I think it would be helpful to maybe define a styling to use in Kata's across the whole website though, so that in the future styling is more cut and dry.

Actually they are a little bit different. The one you linked guarantees a loop exists and the goal is to find the length of the loop. The problem I have created asks you to determine if there is a loop or not. I am kind of new to the site though, is this not sufficiently different?

I feel like it is clear. I read it like its another word in the type similar to "unsigned int" or something similar. Is there a styling guide anywhere on the website?

Thank you! Is there a way to close this?
