A Binary Search Tree (BST) is a type ofBinary Tree data structure, where the following properties must be true for any node "X" in the tree: The X node's left child and all of its descendants (children, children's children, and so on) have lower values than X's value. ...

Binary search trees are tree structures based on binary tree. A binary search tree is a tree-like data structure where each node represents a token. The tree follows two simple rules:All nodes in the left subtree of a node contain values smaller than the node’s value. All nodes in the...

Suppose we have an integer n, we have to count all structurally unique binary search trees that store values from 1 to n. So if the input is 3, then the output will be 5, as the trees will be – To solve this, we will follow these steps – create one array of size n + 1 dp...

Since the binary tree is an essential part of Data Structures and Algorithms, you can expect a couple of questions on binary trees and binary search trees, also known as BST in your programming job interview, likewhether a given tree is a binary search tree or not?
