Then I wrote a small algorithm which finds the minimum and maximum values: no brute force needed- Full code with extra explanation on github.

I first computed bounds and checked within a certain region of velocities. Compared with yesterday this was a piece of cake. I guess for must inputs the solution to part1 is simply y*(y+1)/2 where y is the absolute value of the lower bond - 1. github

Well save to say, this was my least favorite puzzle since 2018: and I still had a lot of fun :) I used two global variables: one keeping track of the current index and adding up the version numbers. I am praying that there won't be a follow up on this :D github

Late bloomers (that started life closer to 30), how are things going for you?

Advent of Code (in MiniScript), Day 17
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.
- Can someone give me a good idea for C# console app I could make?
