Advent of Code 2022

My attempt at https://adventofcode.com/2022. To run, use:

cargo +nightly run -r [-- [-d <days>] [-i <input>]]

Optional arguments:

• days, if specified, returns the solution only for the particular day(s). Otherwise, the solution for all days is returned. Comma separated lists and ranges with - are allowed. Some valid examples are:
  • 4
  • 1,3,5
  • 2-12
  • 1-3,5-7,9-11,13
• input can be specified to a different directory from the default value of "inputs". The expected directory structure is <input>/<day>/input. For example, the input for day 3 at the default path would be inputs/3/input. If a single day is specified, input can also be the path to the input file itself.
