I agree to you. The description should be explain that point like clearly.

@lordware1 +1

The description is literally two lines of text: the first line describes the input, the second one the output.

( The picture was there when you wrote this. Were you so busy looking at that you could not read the text ?!? )

the 7 kyu is a power mod exercise, this is a power tower mod, which is much harder

Which one?

I'd say 6

Or trivial, depending on the language choosed.

yes

True Story

In my opinion, you can definitely solve it without any number theory knowledge... but yes, those solutions are probably much faster.

ofc not. But you won't ever have to write stuff like that in production (if that happens that would surely mean there is a problem in the project itself... x) That or you have really funny guys for colleagues x) )

because solution deifned that way is already a function accepting one argument

Thank you!
