Advent Of Code 2020 – Day 3 – Toboggan Trajectory
Great job reaching here so far. Finally, we've logged in to Toboggan successfully, now we have to travel to the airport through a jungle. The path is not very good and has a lot of trees. So, here comes our next task. The trees in this area only grow on exact integer coordinates in a grid. You make a map (your puzzle input) of the open squares (.) and trees (#) you can see. … [Read more...] about Advent Of Code 2020 – Day 3 – Toboggan Trajectory
Advent Of Code 2020 – DAY 2 – Object-Oriented Way
The Password Philosophy is the topic of today's discussion. Since there is not much to do with today's problem apart from the string parsing, I thought of doing it in an object-oriented way.
