Postorder Traversal
Explore the concept of postorder traversal in binary trees by learning both iterative and recursive methods. Understand how visiting left and right subtrees before the root node impacts tree processing, and see practical code examples to solidify your grasp of this traversal technique.
We'll cover the following...
Iterative postorder tree traversal
Postorder traversal holds enormous value in the theoretical world of computer science and is better at deleting or removing the nodes of tree-like data structures. Like with a linked list, in preorder traversal, we start from the root or head node and then move until we reach the leaf node.
Postorder tree traversal represents just the opposite. Here the root node is visited last. We start from the left subtree, visit the right subtree, and then reach the root ...
