Given a map, with marked land, water, and ???, determine the minimum number of disjoint pieces of land.
Quite a simple flood fill. When you find a piece of land, flood fill everything around it, including clouds, assuming they are land, and count 1 island.
All other clouds (which don't touch land) are considered water. [[Category:Ser2016
