ABSTRACT: During the model-based software testing process, test cases are generated from modeled requirements to conduct acceptance testing. However, existing approaches generate erroneous test cases, ...

Pre, post, and in order traversals of a binary search tree. Each node's key is a character and stores strings that begin with that character.

ABSTRACT: Binary tree is a very important data structure in computer science. Some major properties are discussed. Both recursive and non-recursivetraversal methods of binary tree are discussed in ...

Abstract: Binary tree traversal refers to the process of visiting each node in a specified order. There are two ways to visit a tree: recursively and non-recursively. Most references introduce tree ...

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 ...
