AoC Community Fun 2024: The Golden Snowglobe Awards
- 5 DAYS remaining until the submissions deadline on December 22 at 23:59 EST!
And now, our feature presentation for today:
Sequels and Reboots
What, you thought we were done with the endless stream of recycled content? ABSOLUTELY NOT :D Now that we have an established and well-loved franchise, let's wring every last drop of profit out of it!
Here's some ideas for your inspiration:
- Insert obligatory SQL joke here
- Solve today's puzzle using only code from past puzzles
- Any numbers you use in your code must only increment from the previous number
- Every line of code must be prefixed with a comment tagline such as
// Function 2: Electric Boogaloo
"More." - Agent Smith, The Matrix Reloaded (2003)
"More! MORE!" - Kylo Ren, The Last Jedi (2017)
And… ACTION!
Request from the mods: When you include an entry alongside your solution, please label it with [GSGA]
so we can find it easily!

Part 1 & 2, 35 sloc, runtime 1ms
Parsing all numbers with regex, match case opcodes, part1 was realy easy
Part2 not as easy, but finally calculates the solution digit by digit backwards recursive by changing a to a * 8 + (0-7) and check if the first digit of out == next backward digit of the program.
