I wonder what culture you grew up in that makes you reason "I think this kata is rated too easy, therefore the author should be banned".

Fact is, the author didn't pick the rating at all, it is voted on by the community. Now, you are 3kyu, so there is no excuse for you not knowing that. I therefore request you be filtered by moderation, such arrogance should just be banned. Not cool. Not impressive.

Its not 7 kyu.
Dear author, I have solved it.
Did you want to impress beginners and make fun of them?
Why did you claim its 7 kyu?
8 and 7 kyu are tasks for begginers with entry level who are trying to
find some motivation and learn absolutely basic things like basic methods, data types, etc.
The tasks should be checked and filtered with moderation, and such "comedians" should be just banned.
Not funny at all. Its not cool. U have not impressed anyone, no one cares tbh.

good task, the level corresponds to 7 kyu and the description is sufficient, gj

I have solved it.
BUT its no way kyu 7, its kyu 6 or 5.

extremely disgusting description.
I wish you to always get tasks with such description at work!

wow gud

as i can see from the solutions, this kata is not kyu 7, at least for JS, its a difficult task, I estimate kyu 6.

i think one should be under drugs to invent such a task

Very bad tests.
It says expected / actual vice verse.
Gross mess, needs to be fixed.

Real nonsense, in php cant be passed with NaN
