Advent of Code 2020 solutions in Ruby.
- I'm using Ruby 2.7, but so far any recent version should work.
rspecfor tests - runbundle installto get it set up.
Generally, just run dayN/solution.rb dayN/input.txt to run that day's solution. I usually leave the solution set for part 2 of any given day, but the code for part 1 will be commented out.
Last year I started organizing things into classes and libraries rather than one-off scripts, and I'm continuing that this year.
bundle exec rspec will run the test suite.
