Day 7#

Language sed
Input Method File
Output Method stdout

Running#

Both scripts have a shebang, so you can just do

./part1.sed <path to input file>
./part2.sed <path to input file>

Notes#

Probably the most difficult language I've used so far.

The width of the input is hardcoded, so if you want to run this on a different size input you will need to modify the scripts. Also, be warned that part 2 took around two and a half minutes to run on my (reasonably fast) laptop.
