Thanks, now should be fixed

The expected value is the right value of "should return" but I don't know why it returned -1, I'll investigate it

Thanks akar-0 I understand, I'll try modify it in a way which create a new approach is needed

I really apreciete every comments and report of duplicate or errors when theese are constructive, in codewars there are a many different kind of Fibonacci sequence, FizzBuzz etc.., with different approach or adding extra algorithm, and I think this kata could be one of those, I know that it could be improved to be more challenging or interesting, BTW if mods find this kata a duplicated there is no problem to be unpublish.

Not only does this entail crafting a unique theme or backstory, but would ideally also involve a new, interesting approach to a problem. Maybe this kata has 0 novelty but not duplicated.

Some part of those kata's solutions can be used combined in this kata, but parameters and descriptions are not the same

Now should be fixed

Need to add a basic test with a number with two digit with same value, e.g. 11, otherwise kata can be passed even though solution isn't correct
