## Advent of Code 2021 Solutions in Kotlin
[]()
This repo is my personal attempt at solving the [Advent of Code 2021](http://adventofcode.com/2021) set of problems with
the Kotlin programming language.
I am trying to solve these on the day they are posted with clear, idiomatic solutions. That means in some cases I will
sacrifice performance for a more clear solution. While I will endeavour to have these done day-of I can't promise it
because work and life can get in the way. Plus, some of these problems can get quite involved, so solving it clearly and
writing up an explanation might take me longer than a day. We'll see how it goes! :)
