Here is my rather battered looking tree for this year. Will try to add the missing stars by end of Jan. Will probably start by refactoring some of the early solutions into a general purpose (dfs and bfs) grid traversal library. Learned a ton (about Scala3). And there is still more to be learned. But for now it is a wrap. Merry Christmas and a Happy New Year. See ya all for #AOC2025 #AOC #adventofcode
