AoC-2018-python-solutions

python solutions for Advent of Code 2018
note:
most files are of the following form:

• \d+.py - part 1 solution (normal)
• \d+\^2 - part 2 solution (normal)

however, some files look like this:

• .*plot.py - a plot of the problem.
• .*explained.py - an explanation of how the inefficient (normal) solution works.
• .*efficient.py - an efficient alternative to the normal solution.
• stencil.py - a stencil I've used to start each day.
