Below is an example that I prepared for preorder and postorder traversal of a Binary Tree – enjoy!

Below is the algorithm and C routine for traversing a Binary Tree in postorder.  

A binary tree can be traversed in two basic ways – preorder and postorder. Explained below is the process or preorder traverse of a binary tree with an algorithm and the actual C routine.

Binary Tree is a basic data structure that is used behind the scenes of all major technologies whether it’s a Database system or operating system, search engine, Bleeding edge AI systems, Big data or cloud based architectures.
