in reply to Re^3: traversing a hash looking for path?
in thread traversing a hash looking for path?
For some problems, recursion can be more elegant. For some other problems, it's just another way to do the job. For the remaining few problems, it's just a harder way to do things.
In fact, for this problem, it may be that recursion could be more elegant. My implementation, however, makes no such claim! Especially as you've made a few improvements! 8^)
(In Perl, I'm not very skilled (yet), so you'd be agog at how much time I spent debugging it before posting. I was happy enough to get it done! Once there, I was afraid to touch it in persuit of elegance. We need to get a good golfer in here for that...)
Regarding the altering of the search process: I'd imagine that you may be able to get there with a recursive solution, as well--not that one comes to mind for this task!
I've been meaning to beat Lisp into my brain, but after learning a few programming languages, I've adopted the policy: No learning a new language until I get paid for it! It's too bad I can't convince my boss to let me write anything in Lisp..... So, I'm trying to learn some Lisp-like Perl idioms, but I've got quite a way to go!
