The Nineteenth Byte

Maybe it checks if the power is 1, then it's not (bc it's a decimal) and tries to do some sort of loop for the root, but it's doing a 1th root over and over again?

Unrelated String

i used to know elixir like a year ago so i'm going to try to dive into the source lol

Lyxal

@RedwolfPrograms but then why not just rely on the language's built-in functionality?

I found it trying to answer codegolf.stackexchange.com/questions/215936/…

Redwolf Programs

Oh, true. That's a really odd bug.

Bubbler

What, it doesn't have nth root builtin?

Lyxal

None I can see

I searched both info.txt and the wiki and got nothing

Unrelated String

12:13 AM

this line should be the one firing and i can't imagine what the problem would be

Redwolf Programs

Maybe it's just quirky and not like other exponents :p

Unrelated String

definitely that line

what?

that exponent appears to be fine in elixir

Redwolf Programs

I just tried the same thing, weird

Unrelated String

and i don't see how anything else could be happening in 05ab1e

Lyxal

Okay so am I doing something wrong then?

Is my program incorrect?

caird coinheringaahing

12:18 AM

Bug with z maybe?

Lyxal

No, because it works with other decimals

caird coinheringaahing

z may act differently for 1 than other inputs

For whatever reason

Unrelated String

1.0 is not less than 1

so the problem would have to be in z

Lyxal

But 1.0 == 1 => True

Unrelated String

yeah I can't see what could be going on here either

Bubbler

12:33 AM

This gets stuck in the loop too

Unrelated String

the reciprocal or the reciprocal of 2

*of

lol

caird coinheringaahing

So it doesn't like floating in the form x.0?

Some quick testing suggests so

Bubbler

That's definitely the pow function that is problematic

Lyxal

Then I should update the issue I raised

Bubbler

And apparently the pow was fixed in the recent commits

(one of the added testcase is assert evaluate("T1zm") == 10.0)

so we're just seeing TIO getting stale over time

Lyxal

12:41 AM

Wait, so it's not a bug anymore?

oh

@Razetime It'd be interesting to see what the longest run of 200 rep in a day is on the site

I'm guessing Dennis

Jonah

Bash mystery. If you do bash -c "cat" <<<"hello world", it prints "hello world". The bash sub-process (I think) gets stdin from the here string, and then cat reads from that stdin. But if that's the case, why does bash -c "read x; echo $x" <<<"hello world" print nothing?

Razetime

2:31 AM

@cairdcoinheringaahing maybe an SEDE query would work

caird coinheringaahing

2:45 AM

Just by diving into Dennis' rep history, 16 days is the longest run I could find, from 20/10/16 to 04/11/16 (Of note, Dennis was 58 rep away from making that 22 days)

Redwolf Programs

Lyxal

5:36 AM

They really need to sandbox these for input formats

Bubbler

Crap, applying seven different functions to seven items in an array is nightmare in Factor

pppery

What's wrong with the input format?

Lyxal

It's majorly inconvienient

Bubbler

Split by double newlines, map [split by newlines, join with a space in between, split by spaces]

pppery

I guess it would have been nicer if either all fields were on one line or each field is on it's own line.

Bubbler

5:37 AM

At least it wasn't a major barrier to me

pppery

In my python solution, parsing the input was 25 lines of code (shared by both parts), part 1 was 10 lines, and part 2 was 20 lines

Lyxal

My day 4 sols

Redwolf Programs

I just used a split and map, like 30 bytes overall to parse it into an array of key/value pairs

pppery

Interesting that I took a completely different approach than you.

My part 2 used assert statements to validate each condition,

Bubbler

(I seriously need to learn how to use regex in Factor)

Redwolf Programs

5:41 AM

I'm surprised I only went down one spot on the CGCC leaderboard for taking 15+ minutes on part 2

Bubbler

because apparently lots of people have fumbled in part 2

Redwolf Programs

If they're fumbling I'm running backwards and getting a touchdown for the other team (american football joke :p)

Unrelated String

yeah the empty lines in the input were a big part of how i basically didn't do star 1

not as big as cid

but big nonetheless

Redwolf Programs

What happened with cid?

Lyxal

I still used cid by counting each substring lol

Unrelated String

5:49 AM

lol

I just used a wackass set based approach

Lyxal

Well at least I did before I uploaded to github

sum([(x in r) for x in ["byr", "iyr", "eyr", "hgt", "hcl", "ecl", "pid"]]) in [7, 8]

Unrelated String

and accounting for cid was just a matter of removing it from the set to check against

and i didn't just do something like that because I had the input split on lines because I use input instead of files

Lyxal

5 used lines for part 1 and 41 used lines for part 2

Unrelated String

lmao

Lyxal

as in lines of code

Redwolf Programs

5:51 AM

Were there keys other than the allowed ones that had to be filtered out? If not I wasted a lot of time on that.

Unrelated String

i don't know

Lyxal

I may or may not have written an if-statement for each field

@RedwolfPrograms apparently not

Redwolf Programs

bangs head against table

Unrelated String

i wrote an if for each field on part 2 because i didn't realize how many of the fields were range checks that i could have factored out into a function lmao

At least Factor has a range check builtin, which is called between?

so I simply spammed it throughout part 2
