This was too hard for an 8 KYU, I would prefer it to be 7. Also it seemed like there was a few errors in the spelling and grammer of the discription.

Thank you bro this helped a lot.

I am curious, what is the meaning of lambda?

What is the purpose of the last part? There isn't a case where nums doesn't exist.

Nice it is much longer now.

Thank you, this makes it much better and harder to tell what is happening.

Thanks for the feedback. I am going to unpublish this.

I created this kata, let me know if you think it would be a good kata.

Yes this is the best practices.

This was an interesting question, but I was unable to complete it.

This took me very long to do in Java. I am trying to learn more Java

This was a well explained, fun kata.

Fun question

Why is this only 8 KYU? I think it should be like a 6.

More test cases should be added. Only three of the fixed test cases need you to return False, and the random ones usually never do.
