WebIterative Postorder and Inorder Traversal While iterative preorder traversal is straightforward, with postorder and inorder we run into a complication: we cannot simply swap the order of the lines as with the recursive implementation. In other words, the following does not yield a postorder traversal: WebPost-order traversal can generate a postfix representation ( Reverse Polish notation) of a binary tree. Traversing the depicted arithmetic expression in post-order yields " A B C − * D E + +"; the latter can easily be transformed into machine code to evaluate the expression by a stack machine. Postorder traversal is also used to delete the tree.
