Leaderboard Positions - Part 1: 5114, Part 2: 3147
Hello all! In this puzzle, we are finding the score and rating of different trailheads. A trail is a path starting at 0 (the
trailhead) going to 9 (the trailtail) by only incrementing by 1 each step (ex. 0,1,2,3,4,5,6,7,8,9). In part 1, we need to find the
score of each trailhead, which is how many trailtails it can access. In part 2, we need to find the rating, which is how many unique trails can
be created from a trailhead. In both parts, we can use a graph traversal algorithm like BFS or DFS to find all valid paths. The only different
is whether we prevent repeat searches or not.
