I already did, actually it was easy for a 4kyu challenge, but that day I was a bit stressed and my brain didn't work well at all

well some years ago you couldnt even print "hello world". I mean, your skill is growing so dont be upset. I believe you'll be able to solve this kata soon

i feel the drama too, bro ;O

At the return, you could use sb.substring(0, sb.length() - 1); and it returns a string, so you dont have to use toString()

Thanks, B1ts, very helpful. I think I misinterpreted the compiler message. I thought that the first string of numbers was the input. I read "equal" as "return".

Obviously I have to optimise the code a little further...

You haven't shown us what the "random input" is. The first one is your returned result, the 2nd is expected one.

I'm too weak, this question is too strong... I can't solve this medium problem... How can I be a real engineer? How am I going to get into google?? KUSOOO :(

thank you for pointing that out.

Nice kata :), I think it should be 6kyu

I don't get a single line XD

Took me 4 hours but after all I did it. Very nice kata :D

I did it' let's goooooooooo, so much time spend just for the last test fibonacci... 😅😄😄

I did it!!!! :DDDDDD

Day 3: I can't even figure it out how to do the loop system :(
