OP solved it, closing

That was a year ago- so it's probably irrelevant by now- but just in case-
A little hint- what if left/right nodes got a left/right node of its own?

Never post code or part of code's solutions without the "spoiler" flag... ;)
I flagged it. Those who have already completed the kata can see your message and will be able to answer to you.

That was just miss click, not rage :/
P.S. Ok post "question".

If you need help don't post an issue, post a question.
Not useful to downvote my post...

I know that there is no errors,i've read all coments, but now iam at a nonplus. I dont know how to fix my code.Just asking for some help or hint.

There are no errors in the tests, they are the same in all languages and as you can see at the top of the page 8445 guys passed the kata.

Thx

You can call out code or a command with backticks ` before and after your code, also mark your comment as a spoiler if it contains code.
