A good recursion problem is the problem of finding blobs in a two
dimensional grid. You are give a grid with each square either empty
or filled in. All the squares that are filled in and adjacent to each
other comprise one blob. Your job is to count the number of blobs in
the entire grid. This problem is quite easy to do recursively, but a
real pain, perhaps not even possible to do without recursion. This is
the best, and at present the only problem that I've solved with
recursion that I havn't figured out how to do better interatively.In article In article 28: rec.audio.high-end
