In this paper, we investigate and compare recursive and non-recursive algorithms for in-order, preorder, and post-order traversals. The in-order traversal of a binary search tree is important in ...

**Traversal**: The code performs a preorder traversal of the binary tree. In preorder traversal, each node is visited once in the order: root, left subtree, and then right subtree.

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

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