Post-Order Traversal
Explore post-order traversal in binary trees, where nodes are visited in left-right-root order. Understand the algorithm and see how to implement it in Python. This lesson helps you master post-order traversal, enhancing your grasp of tree structures and traversal techniques useful for coding interviews.

Introduction #
In post-order traversal, the elements are traversed in “left-right-root” order. We first visit the left child, then the right child, and then finally the root/parent node. Here is a high-level description of the post-order traversal algorithm,
-
Traverse the left sub-tree of the ‘currentNode’ recursively by calling the
postOrderPrint()function on it. -
Traverse the right sub-tree of the ‘currentNode’ recursively by ...
