- Search Operation. The algorithm depends on the property of BST that if each left subtree has values below root and each right subtree has values above the root.
- Insert Operation. Inserting a value in the correct position is similar to searching because we try to maintain the rule that the left subtree is lesser than root and the right subtree is larger than root.
- Deletion Operation. There are three cases for deleting a node from a binary search tree. Case I. In the first case, the node to be deleted is the leaf node.

Searching in Binary search tree. Searching means to find or locate a specific element or node in a data structure. In Binary search tree, searching a node is easy because elements in BST are stored in a specific order. The steps of searching a node in Binary Search tree are listed as follows -
Jun 24, 2024 · Binary Search Tree is a data structure used in computer science for organizing and storing data in a sorted manner. Binary search tree follows all properties of binary tree and its left child contains values less than the parent node and the right child contains values greater than the parent node. This hierarchical structure allows for ...
O (n) Fig. 1: A binary search tree of size 9 and depth 3, with 8 at the root. In computer science, a binary search tree ( BST ), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in ...
