Let say you have input array equal [50, 100, 70] and a max distance is 30.
The recuresive function will result with 0, but this kata expect null in such scenario.

Gotcha, thanks!

The program gives you the internal measurements of the frame, but you really need to find the external measurements.

Could you please elaborate on this with a specific example? Why does ["1'", "1'", "1/2""] return "4' 4""? I'm not entirely clear on this.

Random tests are vulnerable to input modification.

really nice

Should work for random test cases - Expected: NaN, instead got: NaN

Never came across such a kata yet that threaded this specific discussion. Would be helpful for you to either explain, post a link to a kata that has a discussion relevant to your input or not bring it up in the first place if you're not going to teach someone who's new to this...

If you want a kata with such comments ( at length ), try this one: Draw a Clock.

Three things: that discussion is over a year old, I found it like this, and I fail to understand why I would have to educate every new user on here. If you can't be bothered to learn, why should I be bothered to teach?

If this is your first authored kata, have a look at this as well: https://github.com/codingforeveryone/READMEs/blob/master/codewars/writing-your-own-kata.md

I could, but it's been done to death. Read the comments on most kata that deal with floating point numbers.

No I meant about the Test.assertApproxEquals

You could have nested any level in tests. Zero, one, more than one. Would have required recursive calls, and would have made for a more interesting kata. As it stands, it's really just another "map and reduce my list".

Can you please explain your reasoning? This is the first kata I created, so I'm new to writing tests and problems on here. Thanks
