Breakdown by Year

• 2015 - 50 / 50 - Challenge - just use Rust.
• 2016 - 14 / 50 - Challenge - Alternate between C, Go, Rust, Python and Zig. Don't use same language twice in a row. Should end up doing each language 5 times.
• 2017 - 0 / 50
• 2018 - 0 / 50
• 2019 - 0 / 50
• 2020 - 0 / 50
• 2021 - 8 / 50 - Not currently documented here, need to re-create
• 2022 - 2 / 50 - Not currently documented here, need to re-create
• 2023 - 6 / 50 - Challenge - Every problem in Rust, Python and Zig. I didn't get far with that challenge as it's just a lot of work. Instead, try every problem in Rust, Python or Zig and you have to do all three before you can re-use one and you can't use the same one twice in a row. E.g. Rust, Zig, Python, Zig, Python, Rust.

Notes

2023 Day 05

Look at the 2023 day 05 I did a big study on this one as it was super interesting for me.

I programmed it in a bunch of languages with multiple different ways to solve the problem. Was a load of fun and really enjoyed doing this even if it absorbed about 2 months of my evenings.

Solutions only!

Respecting the wishes of the author of AoC I've copied all the problems and the inputs but I've encrypted them so as not to distribute them. This is mostly so I can keep them just in case he takes the site offline.

Always respect the wishes of the creators. If you don't like it, go and do something else.

#3 Encrpytion / Decryption Notes

This is mostly for me just in case I forget.

Encrypt

tar -cvzf - problem_solution_input/ | gpg -e -r [id] > problem_solution_input.tar.gz.gpg

Decrypt

gpg -d problem_solution_input.tar.gz.gpg | tar -xvzf -

Challenge Ideas

• Only use functional programming techniques
• Do 1 year using the 25 most popular programming languages, one for each day
  • This looks awful. Cobol, SQL and Scratch... Ada?
  • Can I get toolchains for each of these.
  • Will have to re-do the devcontainer framework.
• Do a year using just Rust - In progress (2015)
• Do a year using a microcontroller - Limited RAM and processor capacity
  • This could also be a container with crippled capabilities just to simulate
  • "every problem has a solution that completes in at most 15 seconds on ten-year-old hardware" is taken from the FAQ
