Days are encoded by %y%d, 2015-12-18 becomes 1518.

All implementations take the input from stdin and print the two solutions for the two parts on separate lines of stdout.

Running a solution

Use the runner script with your language suffix and date, for a Python solution for 2015-12-01, you'd use

./run py/1501

Writing a new solution

• Save your input in a file named according to the year and the day in the input/ subdirectory, 2018-12-14 becomes input/1814.txt.

• Save test inputs and outputs using the same number prefix followed by any non-numeric characters. Test input for 2018-12-14 can become input/1814a.txt and the corresponding output input/1814a.out.

• The output file can have only a single line of output in case you're still working with part 1 of the exercise.

• Write your solution using the same naming convention under the directory of the language you're using. Details may vary by language. For Python, it's py/a1814.py. The a prefix is included so that the module can be loaded into the Python REPL for interactive testing.

• Each language requires a custom Justfile that runs the example with the operations needed for that language. The format for running is

  just run [DAY]
  

  eg.

  just run 1814
  

  in the subdirectory of the language.

• Each solution awaits for input from stdin and prints its results for parts 1 and 2 to stdout as two lines. While only part 1 is finished, the solution prints a single line with the part 1 solution and then exits.
