Advent of Code - Day 14 Part 1 : 58:03 (rank 6724) Part 2 : 4h57:17 (rank 9095) Part 1 went quite smoothly. However, even if I quickly understood which method I had to use in Part 2, I made a lot a silly mistakes and thought that the period to find was very long (several thousands or millions of steps), whereas in my case it was equal to 34. I even submitted a wrong answer for my first attempt, because of a bug in a simulation function. #AdventOfCode
