I just love this event so much. Can�t wait to see the ridiculous saving Christmas scenario Wastl has come up with this year.

That happened last year. The site is asking people not to take up leaderboard positions with AI solvers this year.

my favorite part is that once the problems are out, they stay up and you can still submit an answer years later.

third place in our leaderboard on day 1! :woop:

Second part threw me for a loop.

# ? Dec 1, 2023 06:50

Cybernetic Vermin: Apr 18, 2005

surprisingly tricky for a day 1 yeah, e.g. not quite pure primitives given overlaps can trip things up.

personally i don't care for doing them years later, i plan to attempt to keep strict same-day-solve. but being fairly busy this december that'll probably be difficult enough without learning much new.

I tried to get a private leaderboard going at my work and I think everyone else gave up when they saw part 2.

i rather liked it for my own enjoyment, but i had exactly that thought "wow, real early for a short of tedious parsing exercise" for most people

# ? Dec 1, 2023 20:26

MrQueasy: Nov 15, 2005; Probiot-ICK

day 1 has usually been a parsing or straightforward math problem

part 2 was surprisingly difficult imo because it was difficult to debug, not necessarily because what was needed was overly tricky

as noted i think the issue is that most would reach for the primitives provided by their standard library, and be a bit flummoxed by "returns an iterator providing the *non-overlapping* matches". it is for sure a bit more steep than the last few years.

which is not necessarily bad. but it is new for day 1 i think.

it was especially tedious to debug I think because the example data didn't have hard cases

all my tests pass but there's still something wrong with my part two solution. I'm sure it's something dumb but I've been combing through my debug output for a while trying to find a line that's being parsed incorrectly

this puzzle feels specifically like it's meant to be tricky for chatgpt do solve directly given all the trouble it has with prompts like "how many times does the letter p appear in the word prompt?"

e: sorted it. it was several dumb things

enjoyed remembering how haskell worked for the first time in 11 months, and also making it nice and succinct. fits neatly into a standard terminal window

code:

import Helper
import System.IO
import Data.Char
import Data.List

parseNum :: String -> Int
parseNum x
    | firstDigit x = (digitToInt . head) x
    | otherwise = maybe 0 (+1) $ findIndex (flip isPrefixOf x) l
    where firstDigit = (&&) <$> not . null <*> isDigit . head
          l = ["one","two","three","four","five","six","seven","eight","nine"]

calibrate :: (String -> [Int]) -> String -> Int
calibrate foo = sum . map (calibration . foo) . lines
    where calibration = (+) <$> head . reverse  <*> (10 *) . head

main :: IO ()
main = do
    let part1 = map digitToInt . filter isDigit
    let part2 = filter (/= 0) . map parseNum . tails
    run $ calibrate part1 
    run $ calibrate part2

Most good languages have a find-last in their stdlib these days.

Find last doesn't work for Day 2, though.

I'm also stuck on Day 2, all my tests pass, I get the expected result from the example, but my final answer is wrong. I've checked the first ~100 lines and they're all correct...

...oh, maybe it does, and thats why my answer is wrong. doh.

It does with a regex? \d|one|two|three|four|five|six|seven|eight|nine

So the line I'm stuck on is...
szsvltgsc1onecccbfour3oneightfh

Should the answer be 11 or 18? I assumed it was the first, because one of the examples says zoneight234 should give 14

Edit: cool, thanks...it should be 18. I wish they'd made one of the examples make it explicit.

18. if you have a line that's *just* xxoneightxx, that also parses as 18 because both "one" and "eight" count there.

I am truly sorry for your lots. I couldn't figure out where find-last lives in the kotlin stdlib so I just ran find-first starting from each index of the string because each one was pretty short, and there weren't many lines

# ? Dec 2, 2023 03:50

Achmed Jones: Oct 16, 2004

im not doing advent of code but instead of running a bunch of find-firsts i'd reverse the string and use find-first on eno, owt, etc.

"why would you do that, achmed?" you ask. "that's deranged"

"because you can't stop me"

Solving things this way is very satisfying and advent of code often gives me the opportunity

i asked copilot chat to solve part 2 and it did this but without reversing the searched strings

you could also tailrec backwards splitting the string into beginning/end and just look for the end to start with a match
