The Nineteenth Byte

It's "greedy" in the sense that it wants the longest string possible, +? is "lazy" in the sense that it'll get as little as possible that's still a valid match

Fmbalbuena

ab+? can be ab

Redwolf Programs

No, but it is the same as ab+

Wait nvm

Yeah, it's the same

Fmbalbuena

12:27 AM

+? is "lazy" in the sense that it'll get as little as possible that's still a valid match but there are two matches?

Redwolf Programs

Well, "b" would be all it matches without the g flag

Fmbalbuena

@RedwolfPrograms I have a question

Jo King

... is it a secret?

Fmbalbuena

@JoKing wdym?

Jo King

you have a question but you haven't asked it

Redwolf Programs

12:36 AM

Gtg for now, so you'll have to ask someone else o/

Fmbalbuena

@JoKing Sorry, ~~but i have a question~~

Jo King

i hope it serves you well

Fmbalbuena

@JoKing Regex to check if the number (binary) is divisible by 5

Jo King

probably possible, though it's much easier in decimal

Fmbalbuena

@JoKing I need FSA and I will convert

hyper-neutrino

12:43 AM

i mean it's a bit trivial in decimal :p

Jo King

what's an FSA?

Fmbalbuena

Finite-State Automata

@JoKing do you know?

@JoKing Read this

Jo King

you probably do something like have 5 parts that keep track of each state n of modulo 5, then switch between them for each digit d based on (n=(n*2+d)%5)

@Fmbalbuena umm ok, why don't you do that

Fmbalbuena

@JoKing because i'm lazy

Jo King

i mean, it gives you code that you can use to generate the DFA based on base and divisor

Fmbalbuena

12:50 AM

I can't install pygraphviz

@JoKing are you lazy?

Razetime

@Fmbalbuena just general advice, sometimes not saying everything that comes to mind is good.

Jo King

@Fmbalbuena no apparently

at second glance, it kinda looks like a demented smiley face

Fmbalbuena

@JoKing I will convert to regex

@JoKing This looks like Angry face with some numbers

@OldSandboxPosts remove the tags

Redwolf Programs

1:32 AM

OSP is supposed to remove the tags, IIRC

All I remember is the issue was brought up, and we made a decision one way or another

Fmbalbuena

1:48 AM

@JoKing ^(?:0*(?:1(?:10|0(?:01*01)*01*010|11(?:01*01)*01*010)*(?:0(?:01*01)*1|11(?:01*01)*1))?)*$ but this don't work with test case 1000001

Jo King

i came up with ^(0+|1(10)*(11|0)(01*0(01)*(00|1))*1)+$

Fmbalbuena

@JoKing oh sorry I'm late

@JoKing Can you explain why ^(?:0*(?:1(?:10|0(?:01*01)*01*010|11(?:01*01)*01*010)*(?:0(?:01*01)*1|11(?:01*01)*1))?)*$ don't match 1000001?

Jo King

i don't really know what the process you did to make that regex

A: How to convert finite automata to regular expressions?

There are several methods to do the conversion from finite automata to regular expressions. Here I will describe the one usually taught in school which is very visual. I believe it is the most used in practice. However, writing the algorithm is not such a good idea. State removal method This ...

@JoKing I don't really know what the process you did to make that regex

Jo King

i sorta eyeballed it... how can you get from 0 to 1, how can you get from 1 back to itself, how many ways can you get from 1 to 2, then 2 to itself, then 2 back to 0.

Fmbalbuena

1:55 AM

@JoKing I don't understand

Jo King

there's only one way to return to the 0 node after leaving it, and that's from the 2 node, so you can concentrate on the 0 -> 1 -> 2 -> 0 cycle (and each node's self-cycles)

Neil

@RedwolfPrograms does your laptop not have sleep/suspend mode?

Redwolf Programs

Oh yeah, it probably does

facepalms

Jo King

0 -> 0 is 0+
0 -> 1 is 1
1 -> 1 is (10)*
1 -> 2 is (11|0)
2 -> 2 is (01*0(3 -> 3 is (01)*)(3 -> 2 is (00|1))
2 -> 0 is 1

i assume i'm just doing a simplified/more complicated version of the linked process

i kinda wanna see if there's a shorter way of doing divisibility by 3 now

@Fmbalbuena ends up pretty much the same, the ?:s were making this version look longer

Redwolf Programs

2:32 AM

Well, the layout works, I just can't import it lol

Ooh I restarted my computer, and it works now!

I can do things like þhíß and τηισ now

Unrelated String

niiiice

Redwolf Programs

It should be exactly identical to the Chrome OS US-INTL layout, but with AltGr+G mapped to a dead key for a greek keyboard layout

I'll make AltGr+F or possibly AltGr+M do math stuff eventually

I'll try to cover both Jelly and Husk's code pages, I'd try to include Vyxal too but it's got some weird characters

Maybe I could use something like AltGr+H for the "weird" characters from 05AB1E/Husk/Vyxal that don't fit in with the rest

Unrelated String

2:50 AM

for jelly and husk are you thinking of having a pair of dead keys for overdot and underdot, which map to different characters for non-alphabetic combinations

Redwolf Programs

Chrome OS's INTL keyboard already had overdot and underdot, so I just ported those identically

Unrelated String

ah nice

Redwolf Programs

I suppose I could give them additional functions when used with numbers/symbols

Although it might not be as...discoverable? idk

-20, user was removed :/

-40 here

Redwolf Programs

Someday I'm going to upvote every answer on the site and then delete my account just to mess with people :p

lyxal

the mods would just choose to keep your votes though wouldn't they?

Redwolf Programs

They can do that?

lyxal

pretty sure

because otherwise someone like me could cause a lot of damage

the site would cumulatively lose 110k rep if my votes were deleted

Redwolf Programs

4:44 AM

That is quite a lot of rep

Wait don't votes from long enough ago not change?

hyper-neutrino

pretty sure that's just a default

i believe they can choose to delete votes from however long ago they want. not something I can do though; that's either a CM or a dev thing

i only lost 10 this time, lol

Redwolf Programs

Ooh my rep now contains 69

I'm sorry, but I must delete my account now. I'm done.

It simply can't get any better than this.

This should really be tagged with nice

Your task, is simply to multiply 2 integers given in input, separated by a ",". The catch is, you cannot use the multiplication operator or any loops whatsoever This is code-golf, so shortest code wins! Test cases: i dont know if you even need it! lol 1,0 -> 0 5,6 -> 30 3920,549 -> 2152080
