heh... yeah, good one!

awesome! love it!

True, I have no idea why I've decided to use this function

Same here. Took me quite a while, but it felt really satisfying after I had solved it.

This technically shouldn't count as valid since it will consider strings containing numbers as okay.

How so? Can you give me a name that will break this code?

from the first was fix this very quick, but then if someone name longer or wired and this will be failed.

That was the most difficult kata I've tried so far. It was much easier for me to solve some of the 4 kyu ones. But every one is different, I understand that. Thanks for kata. Took me around 7 hours to make it work

Interesting, great solution 👏 instead of doing the reverse like I did. Time complexity is O(n) if I'm correct, array_sum doesn't have an effect I guess

This is amazing! Some people are so smart. Great solutions

I thought that my solution was hard to read... After seeing this, I'm a happy man

Interesting...

basically took me the whole day , good challenage!

That was the most interesting kata I've had on Codewards so far. Took me around 5 hours to solve it, but I love the fact that it's not easy and easy to understand. Thanks to all the contributors this kata exists. 👏 I wish I could solve it fast like other guys here in the comments, but it is what it is.

It took me 5 hours to solve it. I think it is 100% worth 4 kyu
