Binary Tree Traversal Methods

Binary Tree Traversal Methods. In a traversal of a binary tree, each element of the binary tree is visited exactly once. During the visit of an element, all action (make a clone, display, evaluate the operator, etc.) with respect to this element is taken. Binary Tree Traversal Methods.
