Note: This topic is to talk about Day 1 of the Advent of Code 2019 .

Somebody in the HackerNews thread posted quite readable bash solution .

[image] dimitarvp: I also opted for a helper module that streams the file that maps to the day in question. Yeah, I have a few common helpers, but I try to keep this as small as I can. So mostly reading the file input, and a few frequently needed enum helpers .

Doing the challenge in Elixir this year. My day one solution is a little ugly but gets the job done. advent_of_code/2019/solutions/lib/day_1.ex at master · agundy/advent_of_code · GitHub

Nice. One of my top priorities are terseness and readability. But I can give up some terseness in exchange for code that’s quicker to parse for any random reading human, and it seems you are the same. Brofist? :fist_right: :fist_left: :052:

My solution was pretty vanilla. https://github.com/DarkMarmot/aoc_2019_elixir/blob/master/lib/day1.ex If the boilerplate strategy above holds, I might have to sneak something like that in!

Thanks! If I had known about Stream.drop/1, my part2_with_stream_iteration function would have looked like @sasajuric 's solution.

My solution is eerily similar to a lot of the posts here: https://github.com/trbngr/advent_of_code/blob/master/lib/advent_of_code/2019/day1.ex I did go back and replace the tests with doctests. Should help keep things clear going forward. Great idea!
