advent-of-code-2022

An optimistic attempt to solve Advent of Code 2022 using an emulated BBC Micro Computer.

I'm using the Owlet BBC BASIC editor for now - although if the data grows by much for some of the later challenges I'll probably have to switch to something where I can provide a disk image.

For now, you can copy/paste the code for each solution into the Owlet editor, and hit the run button to see it working...

Solutions

Solution A	Solution B
01A-solution.basic	01B-solution.basic
02A-solution.basic, video	02B-solution.basic
03A-solution.basic	03B-solution.basic
04A-solution.basic	04B-solution.basic
05A-solution.basic	05B-solution.basic
06A-solution.basic	06B-solution.basic
07A-solution.basic	07B-solution.basic
08A-solution.basic	08B-solution.basic
09A-solution.basic	09B-solution.basic (runtime: ~90m)
10A-solution.basic	10B-solution.basic
11A-solution.basic	11B-solution.basic bignum.v1.basic

Beebjit

Beebjit is a super fast BBC Micro emulator. I've used it to crunch solutions for problems that would have taken an inordinate amount of time. So far, that's:

• 11B - This required 10,000 iterations of a complex algorithm that makes use of the bignum library functions (which, in turn, are very slow).

The Beeb

The BBC Micro (affectionately known as the Beeb) is a computer first released by the BBC in 1981. Soon after, they appeared in every school. I was also released in 1981, and I have a bit of a soft spot for these old 8-bit machines.

My brother and I grew up writing little games and programs for them in BBC BASIC.
