*: But part 2 very slow.

General

• There are no deadlines (You don't have to submit day01 on 01. December 2018)
• You may look at other's solutions, or you can do it on your own. Pick your challenge.

Contributing

• To contribute make a pull request with your solution.
• Name your pull-request like this example 'day03-golang'
• Fork repo or ask to join as contributor
• Every solution-file is named 'main' (e.g main.py, main.go, main.ru, main.js, main.cs, ....)

Input

• Each program should expect the input from stdin
• Every folder contains a input-file with testdata you can use.

$ cat day01/input | day01/main

Output

Each program's output(stdout) is expected to match the output-file of each folder:

$ cat day01/input | day01/main
408
55250

.. matches day01/output

408
55250

• Note: Everyone receives unique input-data on adventofcode.com. The correct answer in this repo will not be the correct answer on your adventofcode.com user. Use your own input-data to score points there.
