No, they are inside the class so you can use them all you want. Being private just means they can't be accessed by instantiated objects.

You could remove the first line (empty code comment)

Not entirely, which seems to be my pitfall. I've unpublished the kata so that I can take more time to read through and understand exactly what it takes write an acceptable kata.

Did you already read the docs about authoring?

Thank you for the feedback. It's helpful as this is my first authored kata. Wish the best!

Hi,

• still not enough ;) (compute the expected result first)
• generally, 100 random tests are done.
• note: nothing new here, I think you should unpublish the kata (there are little chances that it gets approvable one day)

Cheers

I appreciate the raised issue. I published without editing the initial solution. It's now fixed.
