"WebImplantation steps of Iterative Inorder using stack We create an empty stack treeStack and push the root node. We also declare pointer currNode to track the current node. Now we run a loop till treeStack is not empty or currNode != NULL Condition 1: If (currNode != NULL) We push currNode into stack for processing currNode and right subtree later.
