My golf for part 8a is complete! github.com/darthbeep/advent-of-code-2022/blob/main/day08/…

I didn't really feel like doing a golf today, but I wanted to test out ChatGPT so I had it golf my code. I was really impressed: github.com/darthbeep/advent-of-code-2022/blob/main/day07/…

Moot point, the index trick cut down a few bytes/

@hyper-neutrino Let's see what this saves.

@hyper-neutrino This one actually took up more bytes. >13 is smart though.

I should also clarify that I'm pretty new to code golf so I'm probably missing out on a ton of fancy tricks.

Giving it a google though.

No actually.

Huh, I've never even heard of that in python.

@AidenChow Thanks! I've been keeping the print(r) on the third line because I'm mostly only counting the second line (same reason I'm not making the filename smaller or using arguments). Had no idea the trick to get rid of sets was possible, time to look into that.

I kind of gave up on jelly, at least for advent of code, but I'm proud of the golf I did in python for today: github.com/darthbeep/advent-of-code-2022/blob/main/day06/…

Mainly because I can tell if x is a sublist of y, but I do that, I can't tell if y is a sublist of x.

Also, now that I'm thinking about it, I'm having a bit of trouble thinking about how to go about solving this. I'd also appreciate tips.

Having trouble parsing today's input in jelly. How do I do something to each element in an array of arrays? I've managed to split on commas with Ỵœṣ€“,”, but I don't know how to further split on dashes.

Yep! Took longer than it should have because I misread the problem, but it was just ŒH€ -> s3. Probably the smallest adjustment I've seen so far between the two parts.

And part 1 is solved! Thank you so much!

Huh, I'm genuinely surprised that made a difference.

For context, ỴŒH€f/€Q€Œs is what I have so far.

@UnrelatedString Also gives all 0s.

Already did €Œs.

i€ØẠ is giving me a bunch of 0s.

Ok yeah I misread the entire thing, I want ØẠ.

I think I have this. I'll tell you if I do though.

Oh wait ØW exists.

And how would I make it index into a concatenated list? I've only ever done operations on single items, not combinations.

Oh smart.

So I don't know what you mean by index into.

Would you mind elaborating? I'm still really new to jelly.

So I can't do ordinal -> blanket subtraction.

I mean on the ascii table.

But in problem 3, there are characters in between Z and a.

Doing problem 3. Managed problem 2 with no if statements.

I also completely don't understand if statements in jelly.

As in, how do I make the code do one operation if the number is greater than 90, and a different if it isn't.

Having a lot of trouble with converting from letter to priority in jelly.

It's not perfect, but I'm really seeing my jelly improving.

Completed day 2! github.com/darthbeep/advent-of-code-2022/tree/main/day02

Useful to know.

Ah.

I keep seeing the phrase "Vectorizes at depth 1." What does it mean?

Yeah I'm not trying to golf yet, I want to get familiar first. I tried learning jelly a while back but lost interest due to not really having a goal, so I'm hoping I can use advent of code to really learn jelly.

And I got part 2! ³œṣ“¶¶”Ỵ€VS€ṢUs3ḢS

I was struggling with getting € to work but after the example I think I understand it.

@UnrelatedString Would you mind explaining? I'm still really new to jelly.

When trying to modify all the y elements in [[x, y], [x, y]] (as in, all of the second elements of sublists), I keep making chains like this _0¦€1%0¦€-3+0¦€3. Is there a shorter way to do this?

Thanks!

Or, now that I think of it, [[y-x, y], [y-x, y]] would also be useful. But either way, I don't know how to make the elements inside arrays interact with each other.

In jelly, how would I take an array that looks a bit like [ [x, y], [x, y]] and turn it into [x-y, x-y]. Assuming an arbitrary length.
