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.
