I agree with above. Each kata in this series could be solved with a tailored solution. Many different strategies fit the different kata's. Very fun and challenging series.

Encouraging post! This will be the first and only kata I do in the series, as the previous are not available in the language I'm practicing. Looking forward to it!

Thanks for the feedback! I added more sample tests.

There are examples for addition and subtration. Can you elaborate it?

Lovely to hear positive feedback!, Made the Example a bit detailed!
