when i use the test i get Test is not defined but when i attempt it works fine. is that a bug. btw what does this kata really teach us ?

this goes to tell you everything is about math

damn

this was a fun one for sure

nice solution took me sometimes but finale got it done

i basically did the same but long way but i think is not the best with O(2n) why is this top in the first place becuase is short or what ?

feels good when your solution is on top

am passing the test but am getting err when I attempt it I don't know why
