You're right, 3*9 = 27, £ == -1, so 27+(-1) == 26

"For example, the number 26 as an input should return 3^"
Is this correct or should it be '3£' ?

added :)

Ruby translation, if you don't mind :)

I've approved it. Oops, sorry, first time mistake I suppose.

Why did you close the Suggestion ?

The translation description has been updated.

Yeah, I think that would be a good idea for js, since you need to be more explicit with numbers than in python. It can probably be mentioned in 'the goal' section.

JS translation

Should the description mention that inputs are BigInts? It currently does not.

fixed, split into positive/negative/zero

Missing it block in sample/fixed tests.

Next time, don't post the solution of the hard kata in the easier one, please (prune out the irrelevant parts before)

Cheers

Yeah that is very similar. I'll unpublish this.

How about this one: Lattice Point Interpolation?

The only kata of that name I can find don't have any resemblance to this kata, so I don't think so.

There is a kata "guess the function" or something like that. Perhaps that's a dupe.
