Okay, thank you very much for fast reply
Can I add you in friends list? Your profile is awesome, looks like you are a genius.
I wanna be really part of codewars community!

I did not look at your exact solution, but by 'wrong' i mean the print/return part.

I solved this kata and submitted it, it was a problem with return the list.
Or anyway my code is wrong?

Please see this paragraph: https://docs.codewars.com/training/troubleshooting#.print-vs-return

Your code is wrong, it's not a kata issue.

Can you explain what I need to do to run tests without this issue? Because I don't have any idea how to solve it...

Test Results:
Fixed Tests
Basic Test Cases
Log
[5, 10, 15, 20, 25]
None should equal [5, 10, 15, 20, 25]
Log
[1, 2]
None should equal [1, 2]

Approved :)

Nice.

Done

Hobovsky and everyone else,

Your right! I got a bit carried away... apologies.

I've withdrawn the comment from my original post.

Perhaps, a lesson for me to think more carefully before I write...

Hello dani1995ar,

Yes I agree --> keep coding... :)

This has been discussed many times before --> but I think the system promotes it...

Not sure about this, I think there's not a single incentive from the system to directly promote a short code. You don't get points for short code, you dont get additional reward for short code.
The only form of promotion of a short code seems to be noobs upvoting short solutions, and, eventually, existence of some golf kata. But one day, they will learn ;)

Hello JohanWiltink, ejini战神 and everyone else,

There are some very clever guys and gals on here.

But, short code seems to be a 'holy grail' on Codewars the shorter the better!

Short, dense code for me is hard to write but also hard to read --> so both writing and reading takes more time for the human...

The machine doesn't care either way...

approved
