Approved.
Ruby translation should be updated 3.0, see relevent information here: https://github.com/codewars/content-issues/wiki/List-of-Ruby-Kata-to-Update
Enabled in this fork
JavaScript version: I think that the fact that tests include numbers larger than
Number.MAX_SAFE_INTEGERshould be mentioned in kata description.But it's already there? Upper limit for
nis specified as10^16, isn't it?Oh, sorry, never mind then, I missed it.
Nice one myjinxin, like all your kata's!
Hello, Testing for: n = 0 Expected: '', instead got: 'Impossible'
May be Expected: 'Impossible'?
Thanks for your feedback ;-) 0 is not a valid input.
1 ≤ n ≤ 10^16, so it's out of the range. I've checked my code. fixed one place which can generate 0 as input(the probability is very low).Just out of curiosity, why doesn't
n = 2not yield a sum.3^0+3^0 = 2, right?Distinct powers of 3. I see.
I can`t slove this: Testing for: n = 243 Expected: '3^5+3^undefined', instead got: '3^5'; Why expected undefined? It is my problem or it is bug?
Okay, I see. Fixed. Thanks for your feedback ;-)
Python, Ruby and Crystal translations delivered, cheers :)
Cheers ;-)
