Firstly we have to find the total number of counts to form a unique binary search tree. After it, we construct all possible unique BST. First of all, we have to know the construction of BST. In a Binary Search Tree, the nodes present in the left subtree wrt. any …
First, we need to know what actually Preorder of a Binary Tree is. Preorder is a type of Binary Tree traversal. In this traversal first, we visit the node. After visiting traverse the left sub-tree first and then right sub-tree. Now, move to what we have to do in this …
In this article, we will read about the Binary Tree Data Structure. Trees are hierarchical data structures where every node has a parent node except the root node. The nodes with no child are called leaves. Need for Trees? 1. Trees are used when we need to store data in …
In this article, we will learn the insertion in a binary tree. We have already seen the concept of BFS in the previous article, so here we will use the same concept to insert the data in a binary tree. The concept is traversing the tree in level order and …
