I'm trying to process a classic child-parent adjacency list using a recursive function and a Stack. This code sorta works - it produces the right result but in an incorrect way, meaning it goes through the recursive function twice as often as it should. So it sorta works for this few entries but fails with a StackOverflowError when using >500 entries. Seems to me the problem is how I end the recursive function when a leaf node is found.
Any help would be greatly appreciated!

never mind...here's my solution...recursion is fiendishly subtle!!
