WebThe class BinaryInorderIterator should be a bidirectional iterator class that encounters the data of a tree in inorder order. The public interface is therefore essentially determined. We use a template parameter representing a TreeType::Navigator in order to have a clean separation between the Iterator and the specific TreeType. WebWe will define iterators for dynamically allocated binary trees that implement the four traversal types (preorder, inorder, postorder, and levelorder) discussed in the first trees chapter. Iterator API Iterators are client-serving devices.
