Morris traversal for Postorder

Morris traversal for Postorder is a DSA topic. In plain words you use it for a short Morris traversal for Postorder example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Morris traversal for Postorder example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Morris traversal for Postorder.

From the example next to this theory: Morris traversal for Postorder — inorder walks left → node → right (sorted order for a BST).

Trap — only saying “Morris traversal for Postorder” with no example. Fix that before you talk about advanced DSA.

Viva: what is Morris traversal for Postorder? Then show the smallest Morris traversal for Postorder example you can type. Then name the trap.

Exam tip

What is Morris traversal for Postorder? Show this: the smallest Morris traversal for Postorder example you can type. Trap: only saying “Morris traversal for Postorder” with no example.

Example

class Node:
    def __init__(self, val, left=None, right=None):
        self.val, self.left, self.right = val, left, right

def inorder(n):
    if not n:
        return []
    return inorder(n.left) + [n.val] + inorder(n.right)

root = Node(2, Node(1), Node(3))
print(inorder(root))

Morris traversal for Postorder — inorder walks left → node → right (sorted order for a BST).
