Is there any way to implement a nonrecursive preorder traversal of a binary tree without using a stack? In a standalone function?<P>the recursive preorder looks like ...

Listing 1. Iteration over a sorted binary tree using recursive descent in an enumeration method. public interface KeyValueTask { void apply(String key, String value ...

We consider a multivariate distributional recursion of sum type, as arises in the probabilistic analysis of algorithms and random trees. We prove an upper tail bound for the solution using Chernoff's ...
