This repository contains all my solutions to Advent of Code 2017.
See the journal for descriptions of the solutions.
As a rule, the programs read the input from stdin. If the input is just a number, then it might be taken as a command-line argument.
I've been using three languages, occasionally in combination with some standard GNU tools. The languages are:
- Clojure
- Python 2.7
- Perl 5
I also made no attempt to reuse code from part 1 in part 2 in any nice way. I treated part 1 and part 2 as different code bases with no possibility to share code, so many problems have a lot of code in common. The reason is simple: I wanted each solution to be standalone and all code visible on the screen at the same time.
You can test run all of the solutions using run-all.sh. The Clojure solutions seem slow, but that is more often than not due to the infamous start-up cost, and not the main function being slow.
The requirements are
- Python 2.7
- Perl 5.10 or later
- leiningen 2
If you really feel like it, you can save your own puzzle input (using Unix line endings) in the input directory and run through all solutions, with exception of day 23 part 2, and possibly day 7 part 2. (Obviously you should not do this just to get 50 stars!)
If you find that my solution does not generate the correct answer for your input (and is not listed as an exception above), please open an issue!
