I see, thank you for the feedback. I'll stop authoring for now and just focus on learning more.

I think because the while loop directly models the problem's sequential reduction requirement. And I kinda notice most of the kata are solved using for loops so it might be nice if there's a kata that can be solved only using while loops.

Thank you for the suggestion!

Thank you so much for the feed back. I'll try ko improve it.

The control flow is unreal

And you use import to solve simple problem hahah

not really. I think solving simple problems with method won't improve your problem solving skills.
