These are my solutions to http://adventofcode.com
All solutions are written in Haskell.
In general, all solutions can be invoked in both of the following ways:
- Without command-line arguments, takes input on standard input.
- With 1+ command-line arguments, reads input from the first, which must be the path to an input file. Arguments beyond the first are ignored.
Some may additionally support other ways:
Day 25 (Combo Breaker): Can also pass the public keys on ARGV
You learn some cool tricks by being around other Haskellers.
Pairs:
[(x, y) | x:ys <- tails xs, y <- ys]Repeated permutations:
replicateM 3 [0, -1, 1]
