My solutions for problems at [http://adventofcode.com/2017]

Go to the specific problem folder and run php [dayXX_YY.php] where XX is the day number (00-25) and YY is the part (1 or 2)

2017 problems are run directly from the 2017 folder. See Readme in folder.

2017 problems may require PHP 7.0 or later due to type hinting.
