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 about how to count subtrees with Sum equal to target in binary tree Problem Given a Binary tree and an integer. You need to find the number of subtrees having the […]

If you want to practice data structure and algorithm programs, you can go through Java coding interview questions. In this post, we will see about Lowest Common Ancestor for n-ary Tree. Problem Given a n-ary tree also known as a Generic Tree and also two nodes. You need to find the Lowest common ancestor of the […]

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. This is one of important interview questions on binary tree. We will see two approaches to check if […]

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 delete a node from binary search tree. There are two parts to it. Search the node After searching that node, delete the node. There are three cases which we […]

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 find lowest common ancestor(LCA) of two nodes in binary tree. Lets understand with example. As you can see here, LCA is nothing but lowest common parent of two nodes. […]
