#Advent of Code 2022

My solutions to Advent of Code 2022. It's my first year participating and I am trying to learn rustlang. I have never programmed in rustlang before.

#Day 2

• Learn to use enums from the beginning. It was too hard to change stuff after the fact when everything was working.

#Day 3

• Although I didnt end up using it, the option module documentation was good to learn about: https://doc.rust-lang.org/std/option/index.html
• Debugger use:

rustc -g main.rs # compiles program so that it can be debugged with gdb debugger
rust-gdb main # run program with gdb debugger

#Day 4

• if elf1 = "4-6", with x = elf1.rsplit('-').collect(), x[0] = 6 and x[1] = 4. I have no idea why
  • fix with elf1.rsplit('-').rev().collect()
