Problems on Binary Tree Implement Binary Tree in Python We have explored the strategy to implement Binary Tree in Python Programming Language with complete explanation and different operations like traversal, search and delete.
Algorithms Types of views in Binary tree We have explored the different types of views of the binary tree (like Left, Right, Top and Bottom View) and discussed how to find them.
Algorithms Convert a binary tree into its mirror tree Given a binary tree, we have to write an algorithm to convert the binary tree to its mirror tree. A mirror tree is another binary tree with left and right children of all non-leaf nodes interchanged.
Problems on Binary Tree Construct Binary Tree from Inorder and Preorder traversal We present two approaches to Construct Binary Tree from Inorder and Preorder traversal. We start with background information on constructing Binary Tree from a given traversal or a set of traversals.
Data Structures Applications of Binary Tree Binary Tree is the most used Tree Data Structure and is used in real life Software systems. We have listed applications of Binary Tree and its variants.
Problems on Binary Tree Level order traversal of a Binary Tree In this article, we have explored Level order traversal of a Binary Tree in depth using two approaches: recursive approach and queue.
Algorithms Zig Zag Traversal of Binary Tree In this article, we present 4 different approaches for Zig Zag Traversal of Binary Tree using stack, deque, recursion and an iterative approach.
Algorithms Check if 2 Binary Trees are isomorphic Two Binary Trees are known as isomorphic if one of them can be obtained from the other one by series of flipping of nodes, swapping the children both left and right of number of nodes.
Algorithms Convert Binary Tree to Circular Doubly Linked list To convert binary tree to circular doubly linked list, we will take left node as previous pointer and right node as next pointer. The order of nodes in Doubly Linked List must be same as in inorder of the given binary tree.
Algorithms Succinct (0-1) Encoding of Binary Tree Succinct (0-1) Encoding of Binary Tree is an approach to encode a Binary Tree to the lowest possible space and maintain the structural information.
Algorithms LCA in Binary Tree using Euler tour and Range Minimum Query In this problem, we will find the Lowest Common Ancestor of a Binary Tree using Euler tour and Range Minimum Query. We can solve the LCA problem by reducing it to a RMQ problem.
Algorithms Lowest Common Ancestor in a Binary Tree In binary trees, for given two nodes a and b, the lowest common ancestor is the node of which both a and b are descendants. We explored the algorithm to find Lowest Common Ancestor in a Binary Tree.
Problems on Binary Tree Operations in Threaded Binary Tree There are three main operations which can be done on a threaded binary tree Insert, Search and Delete operation which we have explained in depth.
Problems on Binary Tree Threaded Binary Tree Threaded binary tree is a simple binary tree but they have a speciality that null pointers of leaf node of the binary tree is set to inorder predecessor or inorder successor.
Problems on Binary Tree Checking if a Binary Tree is foldable A binary tree is foldable if the left subtree and right subtree are mirror images of each other. An empty tree is also foldable. We have presented two algorithms to check if Binary Tree is foldable.
Problems on Binary Tree Serialization and Deserialization of Binary Tree We have presented the process of Serialization and Deserialization of Binary Tree where we convert a Binary Tree into a compress form which can be saved in a file and retrieved back.
Problems on Binary Tree Convert a Binary Tree to a Skewed Binary Tree We have presented the algorithm to Change a Binary Tree to a Skewed Binary Tree (both Increasing Skewed Binary Tree and Decreasing Skewed Binary Tree).
Problems on Binary Tree Check if a Binary Tree is skewed or not We have presented the algorithm to check if a given Binary Tree is skewed or not (can be left or right skewed Binary Tree).
Problems on Binary Tree Introduction to Skewed Binary Tree A binary tree can be called a skewed binary tree if all nodes have one child or no child at all. There are two types: left and right skewed.
Problems on Binary Tree Find ancestors of a given node in a binary tree (Recursive + Iterative) Understand how to find ancestors of a given node in a binary tree recursively and iteratively in linear time O(N).
Problems on Binary Tree Find nodes which are at a distance k from root in a Binary Tree We are given the root of a tree, and an integer k. We need to print all the nodes which are a distance k from the root.
Problems on Binary Tree Find ancestors of a node in Binary tree (Recursive) In this problem, we are given a binary tree and a key k. We need to find out all the ancestors of node k. We have used a recursive approach.
Algorithms Finding nodes at distance K from a given node We have discussed the approach to find out the nodes at k distance from the given node. There are two approaches: one using Breadth First Traversal and other using Percolate Distance.
Problems on Binary Tree Check if a Binary Tree has duplicate values Given a Binary Tree, we will develop an algorithm to check if it has duplicate values. This can be done in linear time O(N) where there are N elements in the Binary Tree.
Problems on Binary Tree Find if a given Binary Tree is a Sub-Tree of another Binary Tree A sub-tree is a tree itself that is the subset of a bigger binary tree. A subtree of a node means that it is the child of that node. In this article, we will find out different ways to find out if a given binary tree is a sub-tree of another binary tree.
