Solutions of Advent of Code (which at least worked with my input files)
Please note that at some point I didn't properly free all the memory I'm using in the end. In most cases it shouldn't be too hard to add this, but I didn't adust up to now. Just wanted to note that I consider this bad style (even though the space is freed by the OS anyway in the end).
While running there shouldn't be no memory leaks, since I free space with no pointer on it normally. But don't be too sure since this isn't checked with a sanitizer or valdrind, so maybe I missed some.
Also note that I used the header files implementing some datastructured from the
bsd libs (tree and queue).
The script get_input.lua can retrive your puzzle input if you run it with a
.sess file only holding your sessionkey. It will store the result in
day<dayNr>.dat. By default the input of the current day is pulled, but you may
specify <day> <year> as commandline options. There are NO checks if the day<dayNr>.dat
file is already present (would be overwritten).
