This repository is dedicated to my attempts at advent of code anno 2017. 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 $6$.
