The Sphinx's Lair

Avi

00:00

so uhhhhh I'm stumped

given that you're given a list of numbers with maximum 1 million and minimum 0

how to keep a running list of the two numbers that are farthest away from each other?

bobble

keep a running maximum number and a running minimum number?

Avi

suppose the first few numbers are like 0, 100, 200, 160, 50

then first 2 = 0 and 100

bobble

oh wait is this differences between pairs?

Avi

first 3 = 0 and 100, or 100 and 200

first 4 = 0 and 100, because 160 cuts 100-200 into 100-160 and 160-200

first 5 = 100-160, because 50 turns 0-50 and 50-100

bobble

oh the problem makes more sense now

Avi

00:04

the question is

can you do this without going over the whole range of adjacent numbers every time

Jeremy Dover

Can you sort first?

bobble

This can be computed in O(n) time on a sorted list

Avi

yeah I kept a sorted set

and it's O(n) to do it once

but if you have to redo it every time that you add a number

it becomes O(n^2) which is no bueno

bobble

flothesof.github.io/farthest-neighbors.html

found a generalization

oh wait not running

drat not applicable

Avi

that's not helpful, I've already seen this :(

I tried thinking if I put a queue of segments

bobble

00:09

you could store a list of ranges

and then each new point, you split the range it falls in

Avi

sorted by distance

bobble

and then see which range is the largest

Avi

but then the question is, how do you do fast lookups on the range

bobble

(I'm thinking specifically of python's range, which has an obscenely fast "in" operator)

oh wait still O(n)

drat

Avi

yeah :(

still O(ranges) so since each n adds a range, it's O(n)

bobble

00:12

is there a known min and max for the given numbers?

Avi

well, yes

bobble

too large to store as an array?

Avi

highest value for a long? :P

bobble

ah

Avi

cp-algorithms.com

btw there are some algorithms here

I'm going down the list hoping to find something

bobble

00:14

The ranges idea could be O(n * log(n)) if you do a binary search to find the matching range

and keep a separate variable for the longest range

which is only updated when necessary

Avi

hmmm

maybe each range is like

first number + distance to the next one

and you can insert by subtracting the distance off and putting it in a new object, with the new num

bobble

it's your algorithm, I'm just tossing idea out

Avi

yeah

I think I've seen something similar with the ranges before

but I'm no expert

at least, not with numbers

graph theory I can do very well

bobble

My favorite program was one that, given data, constructed a most-likely HMM and then ran it through the Viterbi algorithm

because I could legitimately say that my program was programming a program

and then make robot movie references

Sciborg

Resisting the urge to make a CGP Grey reference about bots building bots that build bots.

bobble

00:22

ahhh he's great!

I like his "how to become pope" video the best

Sciborg

He is! I love putting on his podcast while I code :D

bobble

"Not to nitpick (not unlike my podcast, Mostly Nitpicking)...."

North Læraðr

@Sciborg I love CGP

Sciborg

I remember when somebody informed me about the hidden bees in all of his videos, and I spent like an entire day hunting through his archive looking for every bee I could find. Turns out there are a ton

He's a treasure

bobble

He does have the one weird opinion about how death is bad and there shouldn't be any, but he's nice and coherent and not self-contradictory and has logical arguments, which is more than usual, so it's fine

Sciborg

00:26

Honestly even if I don't agree with that, his video on the subject (The Dragon metaphor) was really well-produced and is fun to watch solely for the quality of animation and storytelling.

bobble

does it have any hidden bees?

Sciborg

it might :p

My favorite bee is the plushie bee that hangs out on his desk during videos like The Race for Staten Island

I also get a kick out of the time he literally flew to a different state to look in a library for a lost document from 1955 for one video

bobble

that one was great, I cackled out loud and my family looked at me weird

Sciborg

He was like "the search ends here..."
*jump cuts to him literally on a plane*

"I COULDN'T LET IT GO"

bobble

00:45

@Sciborg, I'm watching some CPG Gray right now. I blame you.

Bubbler

5 hours ago, by bobble

So, maybe, (-sub)MERGE(-d) + SORT is your parsing

bobble

... is completely, utterly wrong?

Bubbler

This is the intended answer.

Avi

sheds a bitter tear

bobble

@Sciborg, you got it!

Bubbler

00:49

Sorry if it didn't work out well

Avi

shrugs

go for it, @Sciborg :)

Bubbler

(especially stuff=SORT part... I should have chosen a better word, maybe "kind"?)

And yeah, it's indeed the first time for me making a CC

bobble

It was understandable, at the very least

Worse for it to be unsolved for a while due to the squickness of the wordplay

merrybot

01:06

@bobble hm

Deusovi

@Bubbler there's that, and the deletion too - you'd need to specify exactly which letters are removed, not just "shells" meaning any number of letters from both sides

(but other than that, it's a good first attempt! grammar's pretty solid, just need to get some of the subtleties, which you'll learn with time. I've seen ~~and made~~ much worse)

Hoaammmmm... Anyways, @Sciborg are you done with your CC?

Sciborg

Wait wait I was gone for a bit, did I solve???

Was (-sub)MERGED(-d) correct??

I have two solves???? :D

Uhhhh hooray!! I'll make a much better C4 than last time I promise! Lol

user478740

02:43

Hopefully

user478740

Sepulcheral? Ummmm

Sciborg

Don't be rude, please. I was just making a good-natured jab at myself.

North Læraðr

@Anonymus25 Yeah, that was kind of mean

@Sciborg Dang you have the same (one less) C4 solved then I have in my entire 2+ years in this chatroom XD

In... three days?

bobble

yes, Sciborg gets all the claps

Sciborg

I genuinely have no idea how! :p

bobble

02:48

A++ level at ~~completely accidental~~ brilliant solutions.

Sciborg

But I really like solving them, they are fun. I'm trying to create a really good one for you guys this time.

bobble

I can check over the wordplay, if you want.

I'm fine with forfeiting a chance at solving, since I don't have one in the first place :P

Sciborg

I think my wordplay is okay, I have thoroughly checked to make sure it is completely clued and that I have the correct definition half/wordplay half format. I'll post in a few minutes when I've tweaked the surface to my liking :)

bobble

Of the three I've gotten, two were me solving right after it got out. So my chance of getting this one goes down drastically every minute after posting. It's like buying a new car! The value depreciates right out of the gate.

North Læraðr

@bobble Ahahahaha

Sciborg

02:54

"Solve it now while it's fresh!"

North Læraðr

That's a great analogy

bobble

basically :)

Sciborg

Is there a general length limit? I'm realizing it is a bit wordy

bobble

Also, I've scrapped the crown-shaped clue pattern idea. I just couldn't work with a pre-set clue placement. I think I will use different-aged bobblies (no points, 1 point, 2 points, 3 points) instead

@Sciborg no, my alicorn one was really long! wordplay legalness matters more.

North Læraðr

Wait Bobblies points matter in age?

Deusovi

02:56

no limit but conciseness is better

bobble

Oct 12 at 20:29, by bobble

the older they are, the more little points they get

North Læraðr

Ah

Wait but you have three points... can your bobblies ever be older than you?

bobble

Yes, there are the elderly ones with points all over. They curse at the baby ones with a single point, since one point is more useful than multiple when you want to poke something.

North Læraðr

Hahaha

Sciborg

Okay, here it is and I hope you enjoy:

CCCC: Elizabeth's throat cut by net strike, limbs removed before five hundred attendees - was badly shaken. (7)

North Læraðr

How do trees drumroll, you may ask? We just do

Wow, that's violent

bobble

my clue had "beheaded baby"

North Læraðr

Nice surface, regardless though

Sciborg

Apologies for how gruesome the surface turned out.

bobble

@NorthLæraðr guessed what I was going to ask?

North Læraðr

03:05

@bobble Of course!

bobble

what is a "net strike"? did she get clobbered with a fishing net?

Avi

was badly shaken = saw* flashbacks

bobble

oh noes

Avi

warsaw has 6 letters unfortunately

Sciborg

has Vietnam flashbacks to days of agony over what saws are

bobble

03:07

I think my chances have gone to zero :(

Avi

can "elizabeth" clue Q (as in queen)?

@experienced solvers

user478740

Ok, this is hard, will this CC recreate the msh madness?

Ankoganit

It's not even been 10 minutes

Sciborg

@Anonymus25 gotta be honest, I find it genuinely funny that you openly insulted my last CCCC a few minutes ago to my face and now you're trying to compliment me on my work on this one

Avi

@Sciborg I'm not sure that's a compliment (however, it depends on how the final solution is)

A "hard" CCCC can go both ways - it can be hard for good reasons (e.g. elegant, misleading), or hard for bad reasons (e.g., overcomplexity, bad definition/WP)

still wondering on the "Elizabeth" for "Q" @experienced solvers

Sciborg

03:23

Fair, I hope this one is hard for good reasons then. I still liked our last one even if it turned out to be a bit easy :p

Avi

yeah it read like a charm (at the price of a slightly incorrect def)

bobble

I usually do best on CCs where the wordplay is 1-2 very simple, clearly clued components. That... doesn't seem to be what's happening here

Avi

this one leans a bit on the complicated side

not as far as your Alicorn Gazette one

bobble

Alicorn Magazine

Avi

ah

Sciborg

03:25

Alicorn Magazine was incredibly complex, I loved it

bobble

and I tried to make up for that one by having a very obvious definition & answer

Avi

it was like a reversal of def and definition

normally you'd expect the def to be complicated and the definition to be simple but it swapped

anyways, I'm off to read some stuff

cheers

bobble

cheers

Sciborg

rubs palms together maniacally in the corner

bobble

is there mustache twirling and cackling?

(it can be a metaphorical mustache)

Sciborg

03:28

Absolutely

I should have included the word "saw" just to make us all have flashbacks

bobble

Sciborg

Or both

bobble

"saw precipitate"

"precipitate saw"

Sciborg

Honestly, it's accurate.

Sciborg

He has two: Stiv, God of Riddles, and Rand al'Thor, the Mighty Dragon.

Sciborg

And his special summon is to piece together Hex items to form Hexomino, Lord of Logic.

bobble

Sciborg

Ooh yeah, Jafe, King of Cryptics is the god who spawns when Deus is at half health

Then you have to fight all of them at once Dark Souls style.

bobble

Can my bobblies be his cheerleader squad?

Sciborg

Your bobblies are both his cheerleader squad and his second special summon, which swarm the battlefield trying to drain your PP (Puzzling Power)

If they latch onto you, you have to quickly shake the controller to shake them off.

bobble

this is a great game we're creating

How Mathematician snake is Adder?

bobble

a mathematician adds numbers, so it is an adder

and there is a kind of a snake called an adder

Deusovi

yep! that's a double-definition clue, where both "mathematician" and "snake" define the answer

bobble

in a double definition (ddef), there are two definitions for the same answer, and both must be compliant with normal non-cryptic crossword rules

YouKnowMe

Mathematicians not only add numbers.

bobble

but it isn't wrong to say that they add numbers

Deusovi

04:20

true! "adder" is not a complete description of what a mathematician is, but it's a workable definition/synonym

YouKnowMe

Oh It requires good vocabulary.

bobble

yep

YouKnowMe

Sorry for asking dumb question. How Reindeer's infamous party is Donner?

Deusovi

good vocabulary helps! you can also look things up if you'd enjoy solving it that way more though

Sciborg

Donner Party :)

Deusovi

04:27

no, it's not dumb! it takes time to get used to cryptics, and some of the clues require knowledge you may not have

Sciborg

Donner is both a reindeer and the name of a doomed expedition that ended in cannibalism.

It's hard to get the hang of, it's okay! You have to kinda think in a weird way at first

Deusovi

Donner is the name of one of Santa's reindeer (en.wikipedia.org/wiki/Santa_Claus%27s_reindeer), and the "Donner Party" was... what Sciborg just described

bobble

Lukas Rotter

09:21

@Anonymus25 Ok, just post one for the start :) Do you want to have them checked for legality?

If so, add the explanation of the wordplay

user478740

13:13

Ok, here it is: Evil pushing a goat. (7)

bobble

13:55

If you want it checked for legality, you have to give wordplay

user478740

Pushing a goat: Nag a ram, so becomes anagram

bobble

where is "anagram" defined?

user478740

Evil: Devious, so angram of devious is Deusovi

bobble

ummm that's not a legal def

Definitions have to be acceptable for a regular, non-cryptic crossword

user478740

Pushing a goat is bothering a goat, so nag a goat or nag a ram

bobble

14:05

Also, you can't do indirect anagrams

(which means if you anagram any letters, they must come directly from the clue)

Gareth McCaughan

Also also, even if everything else worked, pushing a goat would be nagging a ram, so you've got four extra letters.

bobble

darn, how did I not catch that!

user478740

14:18

Ok, number 2: The great christian symbol in letterland. (9)

user478740

Christian symbol: CROSS, letterland refers to WORD, =CROSSWORD

Lukas Rotter

How is "the great" a definition for CROSSWORD?

Gareth McCaughan

14:36

I don't buy "letterland" as a definition for WORD, either. Also, in cryptic clues "in" generally means putting one thing inside another -- so if you had WOCROSSRD, that would be CROSS in WORD, but not CROSSWORD. That's CROSS on WORD or CROSS with WORD or WORD after CROSS, etc., but not CROSS in WORD.

user478740

The great christian symbol, sorry

Q: Cryptic Clue Guide

This post is not a puzzle. There is nothing puzzly hidden inside it or the self-answer, posted at the same time. What exactly is a cryptic crossword clue, and how do I write one?

wordplay puzzle-creation cryptic-clues cryptic-crosswords

Gareth McCaughan

so then is "letterland" defining WORD or CROSSWORD, and in the former case where's the definition of CROSSWORD?

(actually, even in the latter case where's the definition of CROSSWORD? I don't think "letterland" defines CROSSWORD.)

user478740

Let's hope the last one is good: Take a crown, change the buzzers with pointy letters, and add a small hat. (6,3)

Lukas Rotter

Try solving first

Lukas Rotter

bobble hat?

user478740

Dosen't explain the buzzers and pointy letters

user478740

And, small hat is cap

Lukas Rotter

yes, it was just a shot in the dark

since I don't know if the clue is even legal so no idea where to start

user478740

Answer: Bottle cap

Gareth McCaughan

14:43

I think you may underestimate how rigorously specified a thing a cryptic crossword clue is. There's a definite "grammar" that applies to the wordplay parts, a definite structure the whole clue has to have. There are clues that break the rules a bit, but the rules are there for a reason -- to make it possible to solve the clue and know that your solution is right. Impressionistic clues that don't follow the rules tend to make that not true any more, and that's a problem.

(Successful rule-breaking clues generally have the property that when you figure out the setter's unorthodox idea, there's no doubt in your mind that you've got it.)

So, again: in this latest clue, where is the definition?

user478740

Crown: Bobble, buzzers: Bs, pointy letters: Ts, Small hat: Cap

Gareth McCaughan

I think buzzers -> bees -> Bs is too indirect.

North Læraðr

@Sciborg and @bobble I was dying reading your PSE boss fight idea

Gareth McCaughan

Also, in terms of style I'm not keen on being so explicit as "change the buzzers with pointy letters"; generally you want to write clues so that the surface reading gives an entirely false idea of what's actually going on in the wordplay, and this is the exact reverse of that -- it literally tells you what to do. (Just a bit obscurely, with e.g. "buzzers" instead of "Bs" and "pointy letters" instead of "Ts", which I think adds the wrong sort of difficulty.)
