WebA BST is defined as follows: The left subtree of a node contains only nodes with keys less than the node's key. The right subtree of a node contains only nodes with keys greater than the node's key. Both the left and right subtrees must also be binary search trees.

The external nodes are null nodes. The keys are ordered lexicographically, i.e. for each internal node all the keys in the left sub-tree are less than the keys in the node, and all the keys in the right sub-tree are greater.
WebBinary Search Tree A binary search tree is a special kind of binary tree. In binary search tree, the elements in the left and right sub-trees of each node are respectively lesser and greater than the element of that node. Fig. 1 shows a binary search tree.
