A set of Haskell solvers for the Advent of Code 2020
My plan for this year’s Advent of Code is to
work on quickly producing tidy Haskell solutions using only the libraries
included with GHC.
To compile a solver, run
ghc --make -no-keep-hi-files -no-keep-o-files <day_number>
replacing <day_number> with 01, 02, etc. This will produce an executable
with the same name in the current directory.
All solvers take a command line argument indicating which part to solve, and
read their input from stdin. For example, to run part 2 of the Day 1 solver with
the input in input.txt, type:
./01 2 < input.txt
