Iterative preorder traversal can be easily implemented using two stacks. The first stack is used to get the reverse postorder traversal. The steps to get a reverse postorder are similar to iterative preorder. You may also like to see a method which uses only one stack. This article is compiled by Aashish Barnwal.
