All of the categories have to either be unique within their set or the same.

Good idea, added the tag!

Are you sure that's the correct test? That input should definitely result in a truthy output. Which language are you trying to solve it in?

6 kyu was what I initially suggested, but through feedback the level settled in at 7.

Thank you so much!

I agree, it seems like a more roughly explained version of the linked kata.

Might want to specify that the smaller of the two possible angles is to be returned.

Optionally could also include an information that input can always assumed to be a valid amount of hours (0-23) and minutes (0-59).

I might aswell change the description to specify that non-empty string inputs can be assumed. Most languages do not have an empty string test at the moment.

Awesome stuff, merged them all!

Essentially a more complex version. In that version you have to find valid combinations, here you only need to check if a specific given combination is valid.

But yes, it's the same game.

Merged!

Fixed!

Yup, that's exactly what I did now!

Ah, obviously ... my initial random test implemenation was way too naive, should be covered better now!

Huh, I thought it used the most recent one by default. Updated it!
