I occasionally have to write something recursive. Every single time, I have to stare at the screen for quite a while to figure out how to do it. For some reason the part where I decide where to enter the recursion, and where in the loop to exit it, cause me no end of uncertainty. I don't know why it's so difficult for me. I assume it's not everyone who has that problem.
But sometimes nothing but recursion will do. --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* Dad and Mom can share the driving chores, as follows: Dad will start out at the wheel, then Mom will take over as soon as Dad dies.
