I understand your frustration.

Software Developer's reality lies somewhere between a very clear description and "mind reading". A certain level of self-research is almost inevitable. You might need to perform some digging to advise a customer on the best approach or, as in this case, find out why solving particular cases is impossible.

Considering this is not a white kata (levels 7 and 8) I think some amount of research is appropriate.

This comment was key for me to find the solution. Thought I had the concepts right, oh boi I was wrong.

yep! a different approach to fibonacci katas. I think many katas are about kind of understanding the description, and then understanding what is the wanted output with the help of testcases, so description makes more sense!

Thank you.

OP solved it, closing

😃

What do you mean specifically?

I have not solved the kata, however I could still see the comment. Thanks for asking

this should probably have the spoiler tag on it, so I tagged it

The inner function need not be of arity 1.

I see you figured out how to do it. Closing.

thanks :) i had no idea it is even possible, and I chose sort for my solution

On what do you base your opinion?

And wouldn't it be fairer to skip kata you don't want to solve, instead of downvoting them?

I fully agree it's not challenging programmatically. That is completely obvious from the description though; no false advertising here. The challenge is working it out for yourself ( though I see with some amazement people actually just Googled it ).

To put it bluntly, who died and made you God?
