@JorgeAlberto I'm doing well, thanks. I think Code Review might be the site you're after; their entire existence is based around the premise of improving code style.

Doorknob

@JorgeAlberto Why are you asking that here? This is the chatroom for codegolf.stackexchange.com, as it says in the description. You should try the JavaScript chatroom:

JorgeAlberto

@Doorknob srry for that bro, I'll check that room, thanks for the help also @AlexA. I already posted my question but I want tips too, thanks

Alex A.

@JorgeAlberto No problem. As Doorknob said, this room is for Programming Puzzles & Code Golf, where we do programming challenges. The kind of tips we could offer aren't really the kind that will help you write good code; they'd be tips for writing short, unreadable code. :P

Do you think it is too early for me to claim the bounty in the OP of this post? codegolf.stackexchange.com/questions/69060/… No-one else has made any other solutions for a week and I am still the only one to satisfy it.

Luis Mendo

@Dennis I think I solved the issue of unwanted output from symbolic computations. Please pull whenever you have time

Alex A.

@CameronAavik There doesn't appear to be an active bounty on that challenge.

@AlexA. at the end of the post it says "There is a bonus incentive: I will award a bounty to the smallest solution that works for any n and runs log(n). For small n it must be fast (determined at my discretion). Yes, this is possible."

Alex A.

Oh I didn't realize it was part of the post.

I'd wait until the OP has offered the bounty. I'm sure they'll take notice of your post soon enough.

Dennis

@LuisMendo OK, pulled.

Alex A.

Ah man, I saw this Bézout coefficient challenge and thought, "YES! Julia has gcdx which will do this!" Then I noticed that it uses the extended Euclidean algorithm, which is explicitly forbitted in the challenge.

A: Expand the number

Lua, 350 Bytes I think there's two way to golf it down further : I could make use of macro.define to replace some of the commons expressions (can't test right now, and not sure it would make me gain some bytes) Use split on the dot instead of iterating on the whole string. Once again, I'm not ...

A: Primitive Roots of Unity

Jelly, 11 bytes Rg=1O÷×4*@ı I wanted to generate the numbers coprime to N by folding set difference over all of the roots of unity from 1 to N, but I couldn't figure out how so I used @Dennis's method. Rg=1O÷×4*@ı Monadic chain: 6 R Range [1,2,...

Doorknob

The high today is 61 and people keep complaining about how cold it is. I moved here to Houston from Chicago, so... :P

Luis Mendo

@Dennis Thanks! I'll investigate what can be done

TimmyD

Colder the farther north you go. Plus factor in wind chills on top of that. kstp.com/article/stories/s3149999.shtml
