The key of the right child of a node(if it exists)is greater than the key of its parent node 3. The left and right subtrees of the root are again binary search trees
binary searchtree not binary searchtree DEFINITION A binary search tree is a binary tree that is either empty or in which the data entry of every node has a key and satises the conditions: 1. The key of the left child of a node (if it exists) is less than the key of its parent node. 2. The key of the right child of a node (if it exists) is greater than the key of its parent node. 3. The left and right subtrees of the root are again binary search trees. error error

.This method will often be called with a parameter target that contains only a key value. The method will fill target with the complete data belonging to any corresponding Record in the tree o To search for the target we first compare it with the entry at the root of the tree. If their keys match, then we are finished. otherwise, we go to the left subtree or right subtree as appropriate and repeat the search in that subtree oWe program this process by calling an auxiliary recursive function
