Post order traversal of binary tree without recursion

Postorder tree traversal without using recursion. Simplest method are using a stack. and perform Postorder tree traversal.

Suppose following node are contain in binary tree.

Postorder : 4 2 10 8 30 9 3 1

Function : iterative postorder traversal of binary tree.

View pointers and code execution process.

View stack pointers.
