Hi

Just in time

@AviFS You don't need ¨ in =¨

Thanks! @Razetime was just telling me!

He also says I can trainify!

thanks dictionary

Jo King

(but in this case, it's fortnightly)

pxeger

@Bubbler what are you gonna do if I bookmark something else under the name biweekly-mini-golf-6?

Bubbler

What, is that US/UK thing too?

@pxeger Well, I won't be here on #6 so I don't care :P

AviFS

9:43 AM

@betseg Which dictionary said anything about US vs UK, I was always under the impression that was just an ambiguity of the English language, but not regional.

Oh, I see, on Wikitionary

I'm not sure I believe it...

If it's true that it's UK vs US, it's not very well known

Eg. this article & this article

Are dedicated to the issue of what bimonthly really means, and neither one mentions UK/British/US/American, that I can find

Jo King

i would assume that since outside the US we already have a word for every two weeks, so they always assume that biweekly means twice a week

pxeger

is fortnightly not a word used in the US?

AviFS

That's what I'm inferring too, but I don't know if it's actually more likely to be so

Unrelated String

not commonly

AviFS

@pxeger Is fortnightly a word used anywhere?!

Jo King

9:48 AM

i don't play it

Aka, no.

@AviFS I use it

i use it

In fact, I use it regularly enough that you might say I use it fortnightly

AviFS

Are you anywhere?

Unrelated String

9:49 AM

i can't speak for all of us but i can readily recognize what fortnightly means but would not necessarily think to use it

pxeger

I'm in the UK

AviFS

@UnrelatedString Same. It sounds totally antiquated to me.

Bubbler

@AviFS It is used for a recurring event on Puzzling.SE

pxeger

@UnrelatedString I'd probably just say "every two weeks", tbf

AviFS

Sounds to me pretentious & archaic. Which is kind of a recurring theme with British words...

I guess that means we sound unsophisticated & hip by comparison

pxeger

9:51 AM

yup

Unrelated String

i'd say it feels more amusingly archaic than pretentiously archaic

pxeger

bemusingly, mayhaps?

AviFS

Hahahah

@UnrelatedString I see what you mean, but it really depends on the tone imo. It could very easily sound pretentious/try hard if one wasn't careful. In this crowd, I'd assume playful. But in most crowds, if with an American accent, I'd just assume obnoxious.

A username

Excuse myself!

pxeger

If you use too many weird/big words in one sentence you'll always sound silly

AviFS

9:54 AM

But at least then it's obvious that it's "in jest." If you just say "a fortnight" out of the blue here, it's... really weird.

cmc: strings p q r are such that each is [ab]* and now consider the following: continuously replace the left-most instance of p in r with q, until p is no longer in r. the cmc is to find the p, q that takes the longest number of iterations to halt as a function of the length of r. an example, p=ab, q=bba, r=a^nb, which halts in O(2^n) steps. tio.run/##S0oszvj/vzg1RUHdKtG6wLpYPzFJPykpUd@6JNE6UL2mPFlBN@f//…

(A word like hoover sounds specifically British to my ear, whereas a word like fortnight just sounds old fashioned. A Brit would still get away with it obviously, but it'd leave a different taste in my mouth if an American used those two words.)

goto sleep;

@Ausername × takes two arguments: a string, and either 0 or 1, and uppercases or lowercases according to the argument. It's designed to be normally used with a static 0 or 1 in the same way the trigonometric function ○ uses 1-6 for sin/cos/whatever, but it can be used with the input. It also vectorises automatically, so it can be used for this challenge

AviFS

goto sleep fortnightly;

@Bubbler May have been asked already, but what would the expected output for something like 1(2(3) where the 3 is contained within the outer matched parens but not its own inner parens? 23 or 2?

Unrelated String

I would assume 3

Jo King

the example doesn't print 6, so i think the brackets still have to be balanced?

Shaggy

@UnrelatedString :facepalm: missed the leading ( in Bubbler's example so 3 would indeed appear to be the correct solution. Time for more caffeine. Much more!

I recently had a challenge idea, and I wanted to ask feedback for it here, before I post it in the Sandbox.
The idea came from the cat program, but now:
If I execute your code x it should output y, if I replace your code with y you should output x. x and y can't be same.
Is there some sort of very easy way to do this I have overlooked?
