I've done something similar to this in Python before, but this time the completion aspect did throw a little wrinkle into it. That taught me some new stuff about slices, sorting, and idiomatic implementations of a stack in Go. Full source including tests available on Github.

In the spirit of "premature optimization is the root of all evil, I just brute forced it. The test suite ran in 70ms on my system so that was good enough for me not to worry about further optimization.

Like most other folks, I did the naive approach for part 1 and then part 2 was untenable. Props to everyone who did the smart thing from the beginning. As always, my full code including tests is on Github.

This one kicked my ass for a while, which was confusing because the tests all passed fine with example data. Eventually I tracked down the problem to the way I was reading in the actual puzzle input... I should've known. Anyway, in addition to the [Github repo](https://github.com/krmaxwell/aoc2021/master/day4] with full tests and stuff, here's the core answer:

Same as yesterday, my answers using Go are on Github with a TDD-ish approach. I'm not being super strict with TDD here.

Share your go advent of code
My solution for Day 1 is on GitHub. I think you may have made things significantly more complicated than needed.

-🎄- 2021 Day 8 Solutions -🎄-
My solution in python.
-
-🎄- 2021 Day 7 Solutions -🎄-
My solution in python. Brute force, nothing fancy, using the closed formula for the sum of integers less than n.
-
-🎄- 2021 Day 6 Solutions -🎄-
My solution in python, partitioning the population by day until reproduction, and keeping track of the group dynamics through time.
-
-🎄- 2021 Day 5 Solutions -🎄-
My solution in Python. Nothing to boast about: lazy brute force, if that makes any sense. The optional dependency on tqdm helped muster patience.
-
-🎄- 2021 Day 4 Solutions -🎄-
My solution in Python, using a stateful approach that amounts to object-oriented programming.
-
-🎄- 2021 Day 2 Solutions -🎄-
My solution in Python, using list reduction and declarative specification of moves.

-🎄- 2021 Day 1 Solutions -🎄-
My solution in Python, using boolean sums.
