AoC-2022 VS adventofcode

The challenge did inspire some ideas for new libraries and library functions. Over the course of the month, I created an aoc module with a variety of general utility functions that may make their way into the standard Mini Micro library; as well as a search module, which will probably end up as its own repo.

I've now created such a library, and redid last night's challenge using it.

I'm using the list.combinations method (in my AoC module) to find all the different ways we can form setA (my valves) by taking n of the goodValves. Then, we find setB (the elephant's set) by simply removing each of mine from a copy of the full set.

Oh, but I promised some pretty graphics, didn't I? Since I'm doing all this in Mini Micro, those are easy to add (you can see the code here). The GIF at the top of this post shows the movement of the rope for the Part B example. And here's the start of its motion for my real input file... though the full input makes it wander much longer, and much further from the origin. Enjoy!

Once again, my starter program did me no good; nor did I need any of the stuff I've been gathering in my custom aoc module, or even the standard /sys/lib modules. The solution was plain, unadorned MiniScript. ❤️

By this point I have a starter program which reads an input file line by line, has a place to calculate a result for each line, and then does some kind of summary of the results. I didn't need all that for this program, so I cut some stuff out, and (under time pressure) ignored other bits. But with a little more cleaning up, my solution boils down to this:

Given the libraries I had, I don't see how. However, I may add some new tricks to my aoc module. Maybe I should have a "select" method that grabs a subset of a sequence (string or list) given a list of indexes. I could use this on each line to convert the raw input, like [Z] [M] [P], into just the letters, like ZMP (by doing line = line.select(range(1, line.len, 4))). Then I'd have a list of strings like:

If you want to join me, please do! I'm posting all the code on GitHub, including my little lib/aoc module. I encourage you to join us on Discord too, where we can strategize and commiserate. See you there!

My Scala solution – to be cleaned up.

Welcome back to my series of Advent of Code solutions in MiniScript! Day 18 was pretty straightforward, though it presents some interesting choices in how to represent the data -- choices I'm not sure I made optimally.

My Scala solution.

And I've solved all of the Advent of Code problems so far this year, which is utterly unimportant but still brings me joy.

If you'd enjoy some coding challenges, advent of code (https://adventofcode.com/) is currently going on.

Welcome back to my series of Advent of Code solutions in MiniScript! In Day 17 we got to (sort of) play Tetris. Five different Tetris-like shapes fall into a pit, moved left or right on each step according to the input. The first task is to see how high this stack will grow after 2022 blocks have been dropped in.

Welcome back to my series of Advent of Code solutions in MiniScript! Day 16 was... how to put this?
