Rust - Advent Of Code - part 2

Advent of Code is a yearly coding challenge with one problem per day. AdventOfCode.com

Idea here is to meet up several times this month and try to tackle them together in Rust. Trying something new by holding the meetup over Google Hangouts and scheduling it after my kids go to sleep. 🙂

Open to suggestions. Do you want to gather somewhere? Earlier? Different night? Morning? Comments welcome.
