# Advent of code
|
|
This repository is dedicated to my attempts at advent of code anno 2017.
|
|
|
|
Some of the code will be somewhat quick and dirty when I first upload it, since it might be an initial attempt, however things should become somewhat clean after I've rewritten the attempts later.

## The 1st of December
|
|
For the first challenge, part one, one had to review a sequence of digits and find the `sum` of all the digits, which match the next digit in the list. This list is circular, thus the last digit will be able to match with the first digit, such that $`1221`$ will have a `sum` of $`3`$.
|

|
For the second part, one now had to, instead of considering the next digit in the list, consider the digit *halfway around* the circular list, so $`1212`$ would produce a `sum` of $`6`$.
