WebHere is our complete Java program to implement post order traversal of a binary tree in Java without using recursion. The iterative algorithm is encapsulated inside the postOrder () method. We have used the same BinaryTree and TreeNode class to implement a binary tree and then added the postOrder () method to print all nodes of a binary tree ... WebThere are three types of traversal of a binary tree. Inorder tree traversal Preorder tree traversal Postorder tree traversal Inorder Tree Traversal The left subtree is visited first, followed by the root, and finally the right subtree in this traversal strategy. Always keep in mind that any node might be a subtree in and of itself.

WebIn postorder traversal, you first visit the left subtree, then right subtree, and finally you print the value of the node or root. The value of the root is always printed last on post-order traversal. Like many tree algorithms, the … WebPostorder traversal without a stack (or recursion, which is an implicit stack) just involves a lot of careful bookkeeping. It might be easier to understand using a simple but non-trivial example together with some diagrams of what's happening at each step of the algorithm. – Ted Hopp Sep 18, 2014 at 2:46 Add a comment
