Advent of Code 2021 -- Haskell solutions by 'szabi'

Running the solutions

The solutions were executed with GHC 9.0.2, so that's what you should get with ghcup.

To run them, switch into the corresponding day* directory and run them Main.hs:

For the first two days, use

cd day1
runhaskell Main.hs

From the third day on, use

cd day3
cabal run

Branches

The original-attempts branch contains my original solutions. The main branch can contain updates to my solutions inspired by others I found later, and also translations of alternate solutions to compare and study.
