AdventOfCode VS aoc

Solution First solved this in Excel. Here'a snapshot of the mess. After doing it once, writing code to do it for any input turned out to be surprisingly much easier than I had hoped for.

Solution read as a fixed width file, so that all digits became a separate column. After that it was simple column operations.

I did it last year, was a great learning experience and tons of fun seeing everyone else's solutions. Am doing it again this year too. I plan on posting solutions to the thread and Github

Solution

Solution

Busy day today, going back to sleep zzZZZ. Clean solution and walkthrough here later today (hopefully).

If you're using Python, you can check this guy walkthroughs, he's good at explaining things and uses many Python's features to write clean code. I'd suggest to try tackle a problem on your own, and whether you manage to get a solution or not, read his walkthrough, and re-implement a solution using his ideas. This is what I did two years ago and it was a big help for me, I was more and more able to come up with solutions without looking at what he did. I still check what he does today, but I always solve the problem on my own first now.
