I agree, it does seem more challenging. I would say it feels more like a 4-5 kyu level.

Thanks for you comment.

I have modified a little bit description, hopefully it will be easier to understand the kata.

Any other suggestions or ideas how can this kata be improved more ?

Although I am not the original author, I have modified the description to make it clearer.

okay, well if you are that new to coding, don't work on yellow kata, stick with white kata, or work more on your basic skills first. just have reasonable expectations.

Look at the hint at the end of the kata description.
