How to use binary search tree in C++?
The binary search tree has three operations: For the core functionality of C++ Standard template library, we include header file and use std namespace. We define a binary tree with a Node which contains data and pointers to left and right Node of the tree.
Why left and right pointers set to null in binary tree?
Therefore left and right pointers are set to NULL. To implement binary tree, we will define the conditions for new data to enter into our tree. The left sub tree of a node only contain nodes less than the parent node’s key. The right sub tree of a node only contains nodes greter than the parent node’s key.
What programming concepts have we used in binary tree?
We have used Object Oriented Programming (OOP) concepts. A Binary tree is a heirarchichal data structure in which every node has 2 children, also known as left child and right child, as each node has 2 children hence the name “Binary”. Root node is the topmost node of the tree.
What are the properties of a binary search tree?
Binary Search Tree, is a node-based binary tree data structure which has the following properties: The left subtree contains only nodes with data less than the root’s data. The right subtree contains only nodes with data greater than the root’s data.
What is BST (ordered binary search trees)?
Binary Search Trees are also referred to as “Ordered Binary Trees” because of this specific ordering of nodes. From the above BST, we can see that the left subtree has nodes that are less than the root i.e. 45 while the right subtree has the nodes that are greater than 45.
Can duplicate nodes exist in a binary search tree?
Duplicate nodes shouldn’t exist in the tree. The binary search tree has three operations: For the core functionality of C++ Standard template library, we include header file and use std namespace. We define a binary tree with a Node which contains data and pointers to left and right Node of the tree.
