Preorder traversal is defined as a type of tree traversal that follows the Root-Left-Right policy where:...
Given a Binary Tree, the task is to print all root-to-leaf paths of this tree whose xor value is non-zero....
Given a binary tree, the task is to print all the nodes of the binary tree in Pre-order, Post-order, and In-order iteratively using only one stack traversal....
Prerequisite: Generic Trees(N-array Trees)...
A skewed binary tree is a type of binary tree in which all the nodes have only either one child or no child....
Given a Binary Tree of distinct nodes and a pair of nodes. The task is to find and print the path between the two given nodes in the binary tree....
Given an integer Q representing the number of queries and an array where each query has an integer N. Our task is to iterate through each query and find the number of paths such that bitwise AND of all nodes on that path is odd....
Given a binary tree where each node can have at most two child nodes, the task is to find the Euler tour of the binary tree. Euler tour is represented by a pointer to the topmost node in the tree. If the tree is empty, then value of root is NULL....
Given a binary tree in which nodes are numbered from 1 to n. Given a node and a positive integer K. We have to print the Kth ancestor of the given node in the binary tree. If there does not exist any such ancestor then print -1.For example in the below given binary tree, the 2nd ancestor of 5 is 1. 3rd ancestor of node 5 will be -1....
Given a binary tree and a node, we need to write a program to find inorder successor of this node.Inorder Successor of a node in binary tree is the next node in Inorder traversal of the Binary Tree. Inorder Successor is NULL for the last node in Inorder traversal....
The tree is a hierarchical Data Structure. A binary tree is a tree that has at most two children. The node which is on the left of the Binary Tree is called “Left-Child” and the node which is the right is called “Right-Child”. Also, the smaller tree or the subtree in the left of the root node is called the “Left sub-tree” and that is on the right is called “Right sub-tree”....
Given a binary tree and two nodes, the task is to check if the nodes are siblings of each other or not....
