When we learned about recursion it took our teacher 15 minutes to come up
with an example for what the heck it was good for ... and it wasn't even a
good one (can't remember what it was).
I only use recursion when I need to output data stored in a tree format
(you know, each child has a parent, each parent can have multiple
children), otherwise I don't really know what to use recursion for.
Mostly I have database queries where the results are built into 2-3 D
arrays, and then used as the data the recursions work from ... found it to
be the only way doing those trees fast when the data is variable and stored
in a database...
