You are dereferencing a null pointer on the line where you get the error. That is the I have a switch statement, where 'case 3' should traverse (and print) the binary tree with non-recursive Inorder traversal algorithm. However Refer this for recursive preorder traversal of Binary Tree. To convert an inherently recursive procedures to iterative, we need an explicit stack. Following is a Using Stack is the obvious way to traverse tree without recursion. Below is an algorithm for traversing binary tree using stack. See this for step wise step 15 Feb 2011 Here we implement a preorder traversal of a binary tree in a non-recursive fashion. The methodology is as follows: in the recursive version, we 5 Dec 2015 Binary Tree - Preorder Traversal - Non Recursive Approach, Given a binary tree, write a non recursive or iterative algorithm for preorder 31 Dec 2014 4 Nov 2014 Here is source code of the C++ Program to Perform Preorder Non-Recursive Traversal of a Given Binary Tree. The C++ program is successfully 4 Nov 2014 Here is source code of the C++ Program to Perform Inorder Non-Recursive Traversal of a Given Binary Tree. The C++ program is successfully The problem with a non-recursive solution is backtracking. Since there's no way to go back, how can I keep track of previously visited nodes, 20 Nov 2012 We learnt the basics about Binary Search tree in the last post. We are now going to build on top of it. In the last post we did recursive traversal of
