you will not be left with more than 1 number ,

#

infact if you didn't put a while condition , you will end up with an empty list lmao

pearl needle Dec 3, 2021, 7:14 AM

the inputs are structured such that you will always end up with one number remaining

This one was fun!

I think I took 10 minutes on the first one and then 20 minutes on the second one

Sad that personal stats don't show time relative to when you started

I started around 2:50?

what are you guys talking about?

woven oriole Dec 3, 2021, 7:21 AM

my first algorithm was not to create an individual list and cleanup

rather directly make a new binary by the most count (for oxygen)

Advent of Code

https://adventofcode.com/2021

What is Advent of Code?

Advent of Code (AoC) is a series of small programming puzzles for a variety of skill levels, run every year during the month of December.

They are self-contained and are just as appropriate for an expert who wants to stay sharp as they are for a beginner who is just learning to code. Each puzzle calls upon different skills and has two parts that build on a theme.

How do I sign up?

How does scoring work?

For the global leaderboard, the first person to get a star first gets 100 points, the second person gets 99 points, and so on down to 1 point at 100th place.

For private leaderboards, the first person to get a star gets N points, where N is the number of people on the leaderboard. The second person to get the star gets N-1 points and so on and so forth.

Join our private leaderboard!

Come join the Python Discord private leaderboard and compete against other people in the community! Get the join code using .aoc join and visit the private leaderboard page to join our leaderboard.

Y'all ever just... copy your own code wrongly

I really should assign things to variables more often

#

I used an index of i+1 instead of like an i+2 like I intended, and I never noticed unless I tried replicating the examples exactly

hollow wharf only good part about my code for today is that it came out to 69 lines 😎

mine came out to about double that

mine should be a lot shorter

#

I've duplicated so much code

mint hornet Dec 3, 2021, 10:20 AM

Took me 106 lines with quite some whitespaces , wbu?

#

I think I could get it down to 35 or so if I eliminated all my duplicate crap

wary wigeon Dec 3, 2021, 10:27 AM

#

mine is 41 lines

#

for part 2

#

kinda can make it 22 lines

sinful pawn Dec 3, 2021, 10:29 AM

#

Okay, so my actual solution takes up 31 lines

#

Including sample strings, imports, and my own boiler plate, it's 75 lines

#

by "my own boiler plate", this is what I mean:

import ../utils/aoc
import std/os
import std/strutils
import std/strformat
import std/enumerate
import std/math
import std/sequtils

const YEAR = 2021
const DAY = 3
const INPUT_FILE = "Day 3/input.txt"

if not file_exists(INPUT_FILE):
    write_file(INPUT_FILE, get_input(YEAR, DAY))

let input = read_file(INPUT_FILE).strip().split_lines()
let sample = """you get the picture... I've chosen to omit the rest of this"""

#

There is, but they're not called f-strings

there's "fmt" strings and... whatever "&" strings are

Instead of trying to solve it as quickly as possible with messy code, I'm going to take some time to really think it thru before I start. It took me way too long to solve part two because I got hung up on solving it using the first method that came to mind, which was flawed.

this is no good, start anew?

clear cairn Dec 3, 2021, 5:15 PM

haha yeah I'm the same way, if things get too weird I'll just fully start over. I will copy/paste stuff that I know works. That means if my new idea fails I can always go back to troubleshooting the other attempt in place

it's 0...10110, so it gives you 1...01001. first bit is a sign bit https://en.wikipedia.org/wiki/Two's_complement

but because python's ints are unbound, the binary doesn't really have a good representation - that's why e.g. bin(-23) will show it as -0b10111 - being literally '-' and bin(23)

Giving it another look now, you could use a 2d array of 0's, iterate over each wire and mark its path with a number. Say 1 for the first wire, 2 for the second and so on. If a point is already marked it is an intersection and could be marked with an invalid number like -1. If it is marked by your number (say wire 2 crosses itself) leave it the same way. and from there it's looking for the closest -1

#

This may be wrong though. This is just my first instinct

For 2019 day 3 I basically just kept a list of coordinates for each wire

where where you start is 0, 0

the wire crossings are all the points that are common between the two lists

#

the one closest to the beginning is the one that has the smallest x + y

Day6:
The coastguard has brought your sunken body to the ER and you have been pronounced dead. However, your credit card declined and the doctors are trying to bring you back to life to pay. To do so they have to pump out more water out of your lungs rhythmically. For example,

down 2
up 3``` would be pushing one unit down, 2 units down and letting your chest rise 3 units. Test each rhythm until you regain a pulse. You cannot die in debt, good luck.

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

woven sable Dec 4, 2021, 3:30 AM

#

tiny pumice what is AOC session cookie? and how to get it?

You would go to say an endpoint like https://adventofcode.com/2021/day/1

#

then

#

do ctrl + shift + i (developer console)

sleek cave Dec 4, 2021, 3:30 AM

#

basically, developer window on a day -> network tab -> reload page -> click on first thingy you see -> cookies tab within network tab -> see session

woven sable Dec 4, 2021, 3:30 AM

#

head to Network, do ctrl + R

#

or ctrl + shift + R

#

click the first option that shows up in the request, so for the endpoint I gave, 1

#

then go to headers -> request headers -> cookie, and the string after session= is your session cookie

Yeah but we somehow need to signal that to both: fetch(), which needs to completely change its behaviour and lazy_submit(), which needs to completely change its behaviour
