These are my answers for adventofcode.com 2015, written in Java. To run any, you need a Java Compiler (JDK) installed, and on the path
so you can run javac and java from the command-line. From the repository root:
- Compile with something like
javac d01/puzzle.java - and run with something like
java d01.puzzle
Lots of fun puzzles - 19b I eventually "solved" in a spectacularly inelegant way.
