Advent of Code Haskell Solution

This solution aims to write elegant, production level code.

relude package is used as alternative Prelude
Use newtypes for better readablity and more strict typecheck
Use typeclasses for composability
Use pure functions (which never throw exception) only, except functions in input processing

Instruction

# Runs code in year 2019, day 1 with input file stored in 'inputs/' directory.
./run.sh 2019 01

Solutions in 2018 does NOT belong to this stack project.

In order to build & run 2018 code, you might want to use plain GHC:

ghc Day01.hs -o Day01
./Day01 < ../inputs/Y2018/Day01.txt
