Using the Binary tree node class and buildtree methods , implement Preorder, Inorder, Postorder and level order traversals (part1 to 4) of Binary tree iteratively as given in the class definition on next page (name it as BinaryTree.h). Please include and use the stack and queue that comes with C++ for implementing the traversals iteratively: The following sample code demonstrates how we can use the built-in stack and queue that comes with C++ for storing BNode objects
