I have only used Rust for a few hours maybe a year ago, but I really like how you can put unit tests directly in each file with `#[cfg(test)]`. This is especially handy during #AdventOfCode for the example inputs.

My first internship in college involved programming a microcontroller using VBA. Why that even exists, I'm not sure...I wish I could see what I had written now. It was probably horrible.

Yeah, these puzzles are harder than the typical first few days imo

Is "low-allocation" a general term for reducing system calls to allocate memory, or is that a C# specific term?

What sort of runtime did you get operating on strings directly?

I would be surprised if strong manipulation would be faster, but let me know if you find out otherwise!

I appreciate how flexible the puzzles are to experiment with new languages, techniques, algorithms, etc.

What sort of runtime did you get using the hash set? I generated every possible invalid id, sorted the list, and ignored identical adjacent numbers. I would like to try a hash set to compare

Any tips for learning functional programming? I am curious to learn a functional language, but I haven't really had a reason to yet

As I understand it, there is quite a variety of thought within the flat earth community. Some think the earth is semi-infinite, so there is just more earth with no other side. Some people think it's a flat disk with nothing but rock or dirt. Others think it's a snow globe with nothing outside.

Oh, maybe I misunderstood. I would like seeing the diagram on the left if it weren't presented as a way to solve the problem, just as a way to illustrate what's happening on the right.

My main concern is if x is negative, 2x will be to the left of x, and there isn't a way to know that a priori. So from a student's perspective, they'd be really confused half the time when trying to think in terms of the diagram.

If I were a student learning this for the first time, I would find this incredibly confusing for 2x+4=-4. Start at -4, move left four to -8, then... right back to -4? Shouldn't I be at -16 or -12 or something? This assumes you know the relative sizes and positions of things, but you generally don't.
