Yet again I got stuck in the common AOC trap: The example input worked, but not the actual input. 2 things got me stuck. > The size of a basin is the number of locations within the basin, including the low point. The example above has four basins. 1. I missed the obvious part to only check the low points. 2. Based on the example, I asumed that the adjacent locations would increase by one to count. This is wrong: What matters is that their height is a larger value. Way too long time for a simple problem. Never read puzzles sloppy.
