  7. Tree Tree represents the nodes connected by edges.


  8. Binary Tree Binary Tree is a special data structure used for data storage purposes. A binary tree has a special condition that each node can have a maximum of two children. A binary tree has the benefits of both an ordered array and a linked list as search is as quick as in a sorted array and insertion or deletion operation are as fast as in linked list.


  9. Important Terms Path - Path refers to the sequence of nodes along the edges of a tree. .Root-The node at the top of the tree is called root. There is only one root per tree and one path from the root node to any node. Parent Any node except the root node has one edge upward to a node called parent.


  10. Child - The node below a given node connected by its edge downward is called its child node. Leaf - The node which does not have any child node is called the leaf node. Sub-tree - Sub-tree represents the descendants of a node.


  11. Strictly Binary Tree If every non leaf node in binary tree has non empty left and right sub-trees . then the tree is called a strictly binary tree.


  12. 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.
