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 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.
Algorithms Knight’s Tour Problem The Knight's Tour Problem is one of the famous problem in which we have the knight on a chessboard. The knight is supposed to visit every square exactly once. We have explored Backtracking and Warnsdorff's algorithm.
Data Structures Young Tableaus data structure Young Tableaus data structure is a unique form of matrix in which all elements of a row are in sorted order from the left to right and that of a column are in sorted order from top to bottom.
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.
Machine Learning (ML) Concept Whitening in Machine Learning Concept Whitening is a technique that can be used to find the inner functioning. The difference in its approach is that rather than searching for solutions in the trillions of trained parameters it tries to find answers by interpreting the networks.
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.
Problems on Binary Tree Check if a Binary Tree is Balanced by Height In this article, we have explored the algorithm to check if a Binary Tree is balanced by height or not.
Software Engineering Different ways to initialize 2D array in C++ We have explored different types to initialize 2D array in C++ like Sized array, Skipping values and Unsized array initialization.
