- 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.

C++ # Binary Search Tree operations in Python # Create a node class Node: def __init__(self, key): self.key = key self.left = None self.right = None # Inorder traversal def inorder(root): if root is not None: # Traverse left inorder(root.left) # Traverse root print(str(root.key) + "->", end=' ') # Traverse right inorder(root.right) # Insert a node def insert(node, key): # Return a new node if the tree is empty if node is None: return Node(key) # Traverse to the right place and insert the node if key < node.key: node.left = insert(node.left, key) else: node.right = insert(node.right, key) return node # Find the inorder successor def minValueNode(node): current = node # Find the leftmost leaf while(current.left is not None): current = current.left return current # Deleting a node def deleteNode(root, key): # Return if the tree is empty if root is None: return root # Find the node to be deleted if key < root.key: root.left = deleteNode(root.left, key) elif(key > root.key): root.right = deleteNode(root.right, key) else: # If the node is with only one child or no child if root.left is None: temp = root.right root = None return temp elif root.right is None: temp = root.left root = None return temp # If the node has two children, # place the inorder successor in position of the node to be deleted temp = minValueNode(root.right) root.key = temp.key # Delete the inorder successor root.right = deleteNode(root.right, temp.key) return root root = None root = insert(root, 8) root = insert(root, 3) root = insert(root, 1) root = insert(root, 6) root = insert(root, 7) root = insert(root, 10) root = insert(root, 14) root = insert(root, 4) print("Inorder traversal: ", end=' ') inorder(root) print("\nDelete 10") root = deleteNode(root, 10) print("Inorder traversal: ", end=' ') inorder(root)
Now, let's start the topic, the Binary Search tree. What is a Binary Search tree? A binary search tree follows some order to arrange the elements. In a Binary search tree, the value of left node must be smaller than the parent node, and the value of right node must be greater than the parent node.
Jun 24, 2024 · 1. What is a Binary Search Tree? A binary search tree (BST) is a binary tree where every node in the left subtree is less than the root, and every node in the right subtree is of a value greater than the root. The properties of a binary search tree are recursive: if we consider any node as a “root,” these properties will remain true. 2.
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 its right subtree.

May 28, 2024 · Learn how to create, insert, delete, search, and traverse a binary search tree in C++. A binary search tree is a binary tree where each node has only smaller or larger values in its subtree.
