I agree with comments of Joshua B. Should be a higher grade Kata.

Definitely agree, spot on with your comments.

Good Kata, gave me good practise in the use of switch statement.

Hi, I've checked some of the submitted Kata and they are failing on the Tests but appear to have been submitted? They fail on the
shouldReturnFalseOnReversedDoublebrakets(BrakedBalanceTest)
test and they should fail but I was wondering why they appear as solutions?

Hi RySkinz, your code looks fine to me. Re your question, a lot of the Kata can be split into a) those that need more coding skills and b) those that need more maths and logic skills - although our codes show that you can often do them in either way. But if you do web searches for the type of problem at hand, for example, "rectangles within rectangles" with words like combinations, permutations and maths, you will often find a math explanation. Also there is a site called stackoverflow that is very good for programming questions and answers. P.S. I'm largely self taught at coding myself.

I think a few more random tests needed for java

Nice Kata! For Java - it might be an idea to explicity state that there should be exception handling as this is good coding practise.

Yes, this looks better now, good work. Nice kata, I enjoyed solving it.

done a test using x=100 and this returns 26 in my own tests but fails when I submit?
