Let’s look at a few classic examples to see how the concepts discussed above come up in practice. Validate a Binary Search Tree Problem Statement: Given a binary tree, determine if the tree is a valid binary search tree. General Approach: Remember that a BST has the property that for...
If you want to practice data structure and algorithm programs, you can go through 100+ java coding interview questions. 1. Introduction In this article, we will explore the concept of PostOrder traversal in binary trees, focusing on its implementation in Java. In computer science, a binary tree...

19.2 Tree Traversal Ordered rooted trees can be used to store data or algebraic expressions involving numbers, variables, and operations. The process of visiting every vertex of an ordered rooted tree in a systematic way is called tree traversal. Trees are inherently recursive, as every node can...
tree lca(tree t, int a,int b) { if (!t)return NULL; if (t->data == a || t->data == b) return t; tree left=lca(t->left, a, b); tree right=lca(t->right, a, b); if (left != NULL&&right != NULL) return t; return left == NULL ? right : left; }...
Practice with extending a class and overriding methods Part I – implementing a BinaryTree interface The following is a UML representation of a BinaryTree abstract data type. We have provided you with the interface BinaryTree.java and the classes ArrayBasedBinaryTree.java, ...
Postorder traversal of binary tree is: 9 29 21 76 91 80 55 Flowchart: For more Practice: Solve these Related Problems:Modify the program to return postorder traversal as a list. Write a program to perform a non-recursive postorder traversal. Modify the program to print postorder traversal ...
