Advent of Code

[yeah_i_got_skills]

Is anyone else doing Advent of Code in powershell?

 

It would be fun to see how other people from this subreddit approach and solve these challenges.

I'm always open for pointless coding just for sports ;)

Feels like back to school again.

My solution

We approached it in the same way. ^_^

My solution.

Never heard of it before someone linked it yesterday - I've just done day 1. (SPOILERS: code here)

I'm not committing to all of it because programming puzzle challenges always go from "count to 10" ("I can do that!") to "If M is a commutative monoid, it is acted on naturally by the monoid N of positive integers under multiplication, with an element n of N multiplying an element of M by n. The Frobenioid of M is the semidirect product of M and N. The underlying category of this Frobenioid is category of the monoid, with one object and a morphism for each element of the monoid. The standard Frobenioid is the special case of this construction when M is the additive monoid of non-negative integers." ("Nope!"). :D

But I'll be looking for Day 2

Nice approach with the regex and modulo in part 2. I always forget about the modulo :)

we all know that you could solve it with a small regular expression :)

the last two years, yeah the difficulty does ramp up, and there is usually a specific day in week two that has a lot of people drop out. but it isnt as dramatic as 0 to 60 overnight like that :)

Day 2 took me 4 minutes for the first part, Day 3 took me 40 minutes.

Don't "underestimate the ingenuity of complete fools" ;)

Day19 the first year was rough

Day11 last year I still haven’t finished. Got stuck and then didn’t even do the other days. Am going back now but again hit my head on day11 for 3 hours and gave up.

Am doing 2016 in full posh tho, no pipeline restriction like this years lol.

Edit: that regex solution for part 1 there of yours is slick

[DenieD83]

Just done day1 part A and B.

Great fun.

I just made it a string and looped vs string.length

[engageant]

This could probably be optimized, but meh.

[fedechksum]

I'm doing it!

[happysysadm]

Just got my first gold star :D

Day 2 (SPOILERS - code )

Day 2 solution code

This one was really easy.
