Here is my 🦀 Rust solution for the 🎄 AdventOfCode's Day 5: Hydrothermal Venture - Part 1: https://github.com/garciparedes/advent-of-code/blob/master/2021/05_hydrothermal_venture_part_1.rs - Part 2: https://github.com/garciparedes/advent-of-code/blob/master/2021/05_hydrothermal_venture_part_2.rs

Part 1: https://github.com/garciparedes/advent-of-code/blob/master/2020/22_crab_combat_part_1.rs

Here's the relevant extract from my (recursive) solution. Full code on GitHub.

Like others, I used lcm. Here's an extract of the solution, omitting parsing and main(). Full solution on GitHub.

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.

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].

Below is the new solution, which works for part 1 and 2. The full code is on GitHub.

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
