Solutions for the 2021 edition of the Advent of Code - http://adventofcode.com/2021

Back again for another year, the little Advent of Code site that has a new pair of problems to solve each new day (i.e., midnight Eastern time) and this repository holds my solutions using ruby

There are a few files that help with the mechanics of the challenge itself. The value for the session cookie from the site is stored in the ./.session file. The day_prep.rb retrieves the challenge description and builds the initial solution file using the day_template.rb. The input for the day's challenge is retrieved (and cached!) using code from the module defined in input.rb.
