CMC split concatted JSONs in O(n) time. e.g. {"a":42}"x"{} => {"a":42}, "x", {}. You can assume JSON lib encoder/decoder is O(n), where n is len(string).

why advertise google.com

A: Strings without twin letters

Juvana"Strings without twin letters" refers to sequences of characters where no two adjacent letters are identical. These strings exhibit a unique pattern of diversity and often require specific algorithms or methods for identification and manipulation in various programming contexts.click

 
No clue
Seems like a failed spam attempt

TIL there's an apl version called Dyalog APL Vision. But the real question is when will there be the Dyalog APL Vision Pro?

@Adám We need you on this ASAP

Why so many websites require using google chrome, do they use JsFuck and didn't check Firefox? XD
 
Firefox has an option to spoof Chromes user agent to let you access those sites

@lyxal how much does it cost?
 
If you're asking, you can't afford it.

Wow. I just did a chess puzzle which involved forcing the opponent to en passant
Now normally that would go in the gaming room, but forced en passant as an answer?
That's too good to not post here. I have achieved life goals. I will now proceed to Google en passant

@lyxal do you have to take en passant if you can?
 
yes
 
I don't think you do
 
taking en passant is forced
 
I think the rule is that if you want to take en passant you have to do it immediately when it is possible
but you can choose to never do it
@lyxal how is it forced?
 
it's in the rules of chess
 
11:58 AM
ok so the rule is as I described I believe
 
Garry Chess literally told me himself
 
". If the right to capture en passant is not exercised immediately, it is subsequently lost. Making the capture is optional, unless there is no other legal move."
 
he said "lyxal, as the creator of Chess, I decree that en passant is forced"
 
well if Garry said it...
 
he did fr fr no cap
 
11:59 AM
sorry I can't parse that
 
straight up not bussin
 
chatgpt translated it for me :)
at last, a real use!
"fr" is short for "for real," emphasizing the sincerity or truthfulness of the statement.
"no cap" is also slang for "no lie" or "no exaggeration." It's a way of asserting that what was said is genuine and truthful.
 
and what does "did" mean
 
no idea!
 
damn
 
12:04 PM
"Not bussin" can be interpreted as not exciting, not impressive, or not remarkable.
So, in the context of the conversation, Lyxal seems to be saying in a humorous way that what they're saying is indeed truthful but not particularly remarkable or exciting. It's part of the casual and playful tone of the conversation.
 
@Simd based asf. ChatGPT glowup moment, got that zoomer translation drip (iykyk).
 
So, when someone says "based asf," they're saying that something or someone is exceptionally authentic, true to themselves, or unapologetically genuine. It's often used to express admiration or agreement with someone's actions or statements.
 
no no let chatgpt cook
it's got that gen z rizz
 
does anyone know if they are in gen z?
 
12:20 PM
I've created somewhat of a litmus test to find out. If you laugh at the following image, you're gen z
 
I am officially not gen z!
but what if you never laugh at anything?
12 – 27 apparently
who knew
 
1:25 PM
@lyxal 🙂 IFunny

@lyxal i wasnt going to laugh but I saw the ifunny and immediently laughed
 
@lyxal Never before have I felt more old
 
> hehe i added a hat lol
 
2:29 PM
It was "nahhh bird bag :despair:" that got me lol
 
i didn't laugh until ginger pointed out the oversized smiley face
 
3:03 PM
@SandboxPosts as mentioned in my post this really feels like a dup, but the most similar existing challenge i could find was that highly downvoted one i linked to
like, how have we not gotten a vanilla "swap letter cases" challenge yet?
 
3:50 PM
Is the site being super slow for anyone else?
 
@pxeger Yes
 
4:36 PM
@mousetail hrm this reply is in my message input box i wonder what message its replying to
lol
@mousetail wait really? cool!

CMC Given an array of integers A, the task is to output two new arrays. One array B of the same length as A so that B[i] is the maximum over A for every index that is not i and another C which is the same length as A so that C[i] is the index in A that is the maximum over A for every index that is not i

Evening all
If I choose 1,000,000 64 bit numbers uniformly at random, what is the chance of getting no duplicates?
 
Google birthday paradox
 
holy hell
 
Sorry, I was a topology student.
But I guess it's (2^64 choose 1,000,000) times 1,000,000! out of (2^64)^1,000,000.
Which is a stupid rational number.
 
That looks hard to compute
 
Yeah.
 
9:41 PM
Unless anyone has a computer :)
 
I guess even 16EiB cannot store that.
 
Hmmm
This must be doable
 
Related fact: By South Korean standards, "m choose n" is written "mCn".
 
That is similar to the west
 
With m and n subscripted.
@Simd Whose west?
 
9:47 PM
Looks like it is approx e^{-10^12/2^65} if I am reading the wiki correctly
@DannyuNDos Putin's
 
That's... one way to refer to Europe, I guess.
 
😁
 
Another related fact: Getting the numbers all same is more likely than getting the numbers all different when rolling 7d6.
 
It's that true for any number of d6?
I guess not
 
True only for 7 or more d6.
 
9:52 PM
Nice fact
 
This fact is kind of a trick. Because the latter chance is zero.
 
@Simd why do you always ask these weirdly specific complicated probability (and other maths too) questions?
@DannyuNDos same in america
 
And in Australia
 
10:29 PM
@Seggan which ones are the weirdest?
 
@Simd i meant "weird" as in "weirdly specific"
