BUT YOU ALSO HAVE SUPER LOW SOLUTION THAT ISNT POSSIBLE

real hinge Dec 6, 2023, 11:07 AM

#

Wrong

#

Its possible

tranquil vapor Dec 6, 2023, 11:07 AM

#

its cause ur integers are capped to 32bit or smth

#

mine are infinite so it grows so big

#

i think the fix is to discard lower cards

#

not use an array

#

or rather make the array only 5 big

#

cause u only need that much

#

and shift all elements after each iteration

real hinge Dec 6, 2023, 11:07 AM

#

21 digit

tranquil vapor Dec 6, 2023, 11:08 AM

#

cause i currently just push to array

#

so if there are 1 million lines it will make 1 million element array

#

trolley

hazy sinew Dec 6, 2023, 11:08 AM

#

tranquil vapor or rather make the array only 5 big

u can win 16

tranquil vapor Dec 6, 2023, 11:08 AM

#

ohh

#

u made longer ranges

hazy sinew Dec 6, 2023, 11:09 AM

#

but the issue is, i made it so that it repeats 15 times a 25% chance to add one of the winning numbers to the scratch card

#

so there is gonna be a lot of winning cards

the worse you are at it the earlier you wil drop out so youll waste less power, but the better you are the faster your code will be, so its also less power, being average is the worst

cuz youll be bruteforcing day 19

ohh

#

yep

#

i posted code and immediately realised my mistake

#

THAT MADE IT SLOWER???

#

modulo slower than array rotate

#

yeah i tried to optimise it further and it's still slower than array rotate

#

funny

#

ig it makes sense cause array rotate is just a memcpy

#

and modulo is expensive

#

but i wouldnt expect modulo to be slower than memcpy...

#

holy shit i made it faster by not using regex to parse lines

lol day 6 seems like yet another puzzle where brute force wont work

on huge inputs u use the quadratic formula

tranquil vapor Dec 6, 2023, 1:25 PM

hazy sinew i dont think parsing is why its slow

yeah. it made a huge difference on the normal input (30% speed up), but only made like a 1s difference on the large input

#

I'm still confused modulo was slower tho

#

did the compiler realise what I was doing and optimise the rotating to smth different?

----- Day 7: Dimensions?! -----
You wake up to the sound of excited elves, it turns out you've slept for 2 million years and the interdimensional rocket transfer boost coordination system is corrupted.

The technician elf gives you the log and asks you to read it to him, stating that he doesn't speak SHA-256.

For example:

You translate to the elf: "Press the big red button"

He tries, but nothing happens, you receive another log (Your puzzle input), and the elf asks you to translate.

What is the decoded instruction?

Lib.rs/num-bigint

#

For example

#

In computer science, arbitrary-precision arithmetic, also called bignum arithmetic, multiple-precision arithmetic, or sometimes infinite-precision arithmetic, indicates that calculations are performed on numbers whose digits of precision are limited only by the available memory of the host system. This contrasts with the faster fixed-precision arithmetic found in most arithmetic logic unit (ALU) hardware, which typically offers between 8 and 64 bits of precision.

now how do u do this with math

im pretty sure theres a formula to calculate this

real hinge Dec 6, 2023, 3:01 PM

so uhh

#

idk

#

but theres fast way to do this probably

#

getting limit from start

#

and end

#

any number between will work probably

tranquil vapor Dec 6, 2023, 3:03 PM

#

real hinge getting limit from start

yeah thats what i do

#

|| i use binary search to find the smallest and highest number that wins, then just everything between those wins ||

tranquil vapor i wish it didnt use submit time as a metric

I love this system

#

So I can say I did it later instead of I wasted 1 hour on solution

#

Well its usually combination of both

#

But whatever

tranquil vapor Dec 6, 2023, 3:12 PM

#

you know what would make it way better

#

mm actually

#

i was gonna say make it start counting the moment you load the exercise for the first time

#

so it measures how long you took instead of just time since american midnight

#

but then u could cheat :I

#

cheaters ruining evrything

solemn python Dec 6, 2023, 3:13 PM

#

tranquil vapor im pretty sure theres a formula to calculate this

There is

#

But it's a quadratic

#

The first root is lower bound of success, and the second is the upper

#

Or maybe that's reversed idk, abs it

tranquil vapor Dec 6, 2023, 3:15 PM

#

x * (n - x) > y

where y is the record, and n is the time

#

solve for x

real hinge Dec 6, 2023, 3:15 PM

Yep

tranquil vapor Dec 6, 2023, 3:15 PM

#

tranquil vapor ``` x * (n - x) > y ``` where y is the record, and n is the time

but how do you calculate the smallest and biggest x that match that formula

solemn python Dec 6, 2023, 3:16 PM

#

quadratic

#

Set that equal to the record distance

#

And set = 0

tranquil vapor Dec 6, 2023, 3:16 PM

#

riiight omg its a quadratic formula

#

x² - nx + y < 0

solemn python Dec 6, 2023, 3:17 PM

I found https://lib.rs/num-irrational which does quadratics with arbitrary precision

num-irrational is based on num and extends it with support for several kinds of irrational numbers

If I ever need it I just programmed my ti84 to do the quadratic formula for me

tranquil vapor Dec 6, 2023, 3:25 PM

i learned the pq formula for school but i forgot it again cause its useless

i was gonna say what if we added webhooks for everyones repo here but then i realised that'll let anyone at everyone

#

i wish discord would let u configure allowed mentions for a webhook

#

instead of putting that "responsibility" to the webhook executor

solemn python Dec 6, 2023, 3:29 PM

#

You could run a proxy or something but that might be too much effort

tranquil vapor Dec 6, 2023, 3:30 PM

#

i already do actually xd

#

https://ghwp.vendicated.dev

GitHubWebhookProxy

A proxy to filter star spam from GitHub Webhooks

#

could just add additional settings

#

but rn it doesn't hide the webhook urls so it'd be worthless

#

the link is just https://ghwp.vendicated.dev/webhook?url=https://discord.com/api/webhooks/....

#

obv you could just use the original webhook

#

to fix it i'd need to make my proxy have a database and give you an url like https://ghwp.vendicated.dev/webhook/skoppüolsaß0⁰19ijiasjido but im scared that then skids will abuse it for their shitty tokenloggers

----- Day 7: Dimensions?! -----
You wake up to the sound of excited elves, it turns out you've slept for 2 million years and the interdimensional rocket transfer boost coordination system is corrupted.

The technician elf gives you the log and asks you to read it to him, stating that he doesn't speak SHA-256.

For example:

You translate to the elf: "Press the big red button"

He tries, but nothing happens, you receive another log (Your puzzle input), and the elf asks you to translate.

What is the decoded instruction?

Answer: [ ] Submit

----- Part Two -----

Only nonsense comes out, the elf looks at the instructions in confusion: It turns out, it's actually SHA-512, each 2 lines being 1 string.

What is the new decoded instruction?

Answer: [ ] Submit
