How to organize Rust code for Advent of Code puzzles?
I found this repository which solves the problem by having a src/main.rs file which basically calls cargo run --release {day} and parses the output to extract the time each day took, but I don't find this very satisfactory. I'd prefer to have everything compiled into the same executable, without having to run external commands.

-🎄- 2022 Day 14 Solutions -🎄-
Solutions to parts 1 and 2 nearly identical and pretty much worked first time. Nothing clever here. This was far simpler than I thought it would be. I probably spent most time trying to think of a mathematical way of getting all points between p1 and p2. In the end, I just constructed two ranges. Full code here.

The core of my solution below using numpy (because I'm learning it!). See github for full code.

-🎄- 2022 Day 8 Solutions -🎄-
Python 3 solution using numpy. I got held up because I assume (but know better) that numpy arrays are [x,y] instead of [row, col], which is [y,x].

These are the key functions. The whole code is on GitHub

Part 2 (extract shown below) was a matter of starting with the low points found in part 1 then recursively looking around for relevant points. Full code on GitHub
