A binary tree in which for each node, value of all the nodes in left subtree is less or equal and value of all the nodes in right subtree is greater The idea: We can use set boundry for each node. We take C tree for example: For root node, the B (bountry) = [MIN, MAX] nod...

Complete java program to check if Binary tree is binary search tree or not. If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. In this post, we will see how to check if given binary tree is binary search tree or not....

Step1: Check for the condition that the current node is not NULL, if not then go to step 2 else return 1 because a NULL tree is a BST.Step2: Check for the other condition that if the data of any node in the tree is less than the value of INT_MIN and greater than the value ...
Binary Search is only guaranteed to work properly if the array being searched is sorted. Is the statement true or false? Searching: Searching is the technique used to search for one element in a given list. A search strategy is a procedure that ...
Here, we are going to see given an array how can we check whether the given array can represent preorder traversal of a binary search tree or not. For example, Let's take two example Where one is a valid preorder traversal and another is not ...
Given a binary tree where each 𝙽𝚘𝚍𝚎 contains a key, determine whether it is a binary search tree. Use extra space proportional to the height of the tree. 分析: 就是递归遍历BST,将每个节点x分别与x.left和x.right比大小。
