+    "first": "The Elves resume water filtering operations! Clean water starts flowing over the edge of Island Island.\n\nThey offer to help *you* go over the edge of Island Island, too! Just hold on tight to one end of this impossibly long rope and they'll lower you down a safe distance from the massive waterfall you just created.\n\nAs you finally reach Snow Island, you see that the water isn't really reaching the ground: it's being *absorbed by the air* itself. It looks like you'll finally have a little downtime while the moisture builds up to snow-producing levels. Snow Island is pretty scenic, even without any snow; why not take a walk?\n\nThere's a map of nearby hiking trails (your puzzle input) that indicates *paths* (`.`), *forest* (`#`), and steep *slopes* (`^`, `>`, `v`, and `<`).\n\nFor example:\n\n```\n#.#####################\n#.......#########...###\n#######.#########.#.###\n###.....#.>.>.###.#.###\n###v#####.#v#.###.#.###\n###.>...#.#.#.....#...#\n###v###.#.#.#########.#\n###...#.#.#.......#...#\n#####.#.#.#######.#.###\n#.....#.#.#.......#...#\n#.#####.#.#.#########v#\n#.#...#...#...###...>.#\n#.#.#v#######v###.###v#\n#...#.>.#...>.>.#.###.#\n#####v#.#.###v#.#.###.#\n#.....#...#...#.#.#...#\n#.#########.###.#.#.###\n#...###...#...#...#.###\n###.###.#.###v#####v###\n#...#...#.#.>.>.#.>.###\n#.###.###.#.###.#.#v###\n#.....###...###...#...#\n#####################.#\n\n```\n\nYou're currently on the single path tile in the top row; your goal is to reach the single path tile in the bottom row. Because of all the mist from the waterfall, the slopes are probably quite *icy*; if you step onto a slope tile, your next step must be *downhill* (in the direction the arrow is pointing). To make sure you have the most scenic hike possible, *never step onto the same tile twice*. What is the longest hike you can take?\n\nIn the example above, the longest hike you can take is marked with `O`, and your starting position is marked `S`:\n\n```\n#S#####################\n#OOOOOOO#########...###\n#######O#########.#.###\n###OOOOO#OOO>.###.#.###\n###O#####O#O#.###.#.###\n###OOOOO#O#O#.....#...#\n###v###O#O#O#########.#\n###...#O#O#OOOOOOO#...#\n#####.#O#O#######O#.###\n#.....#O#O#OOOOOOO#...#\n#.#####O#O#O#########v#\n#.#...#OOO#OOO###OOOOO#\n#.#.#v#######O###O###O#\n#...#.>.#...>OOO#O###O#\n#####v#.#.###v#O#O###O#\n#.....#...#...#O#O#OOO#\n#.#########.###O#O#O###\n#...###...#...#OOO#O###\n###.###.#.###v#####O###\n#...#...#.#.>.>.#.>O###\n#.###.###.#.###.#.#O###\n#.....###...###...#OOO#\n#####################O#\n\n```\n\nThis hike contains `*94*` steps. (The other possible hikes you could have taken were `90`, `86`, `82`, `82`, and `74` steps long.)\n\nFind the longest hike you can take through the hiking trails listed on your map. *How many steps long is the longest hike?*\n\nTo begin, [get your puzzle input](23/input).\n\nAnswer:"
