Given a Binary Tree, find the Right/Left view of it. The right view of a Binary Tree is a set of nodes visible when the tree is viewed from the right side. The left view of a Binary Tree is a set of nodes visible when the tree is viewed from the left side.

Given a Binary Tree, return its Bottom View. The Bottom View of a Binary Tree is the set of nodes visible when we see the tree from the bottom.

Given a Binary Tree, return its Top View. The Top View of a Binary Tree is the set of nodes visible when we see the tree from the top.

Given the root of a Binary Tree, return the preorder, inorder and postorder traversal sequence of the given tree by making just one traversal.
software development interview question
null
Given a Binary Tree, return the Vertical Order Traversal of it starting from the Leftmost level to the Rightmost level. If there are multiple nodes passing through a vertical line, then they should be printed as they appear in level order traversal of the tree.
software development interview question
null
Given a Binary Tree, return its maximum width. The maximum width of a Binary Tree is the maximum diameter among all its levels. The width or diameter of a level is the number of nodes between the leftmost and rightmost nodes.

Given the root of a Binary Tree, returns an array containing the level order traversal of the tree.
software development interview question
null
Given the root of a Binary Tree, return the height of the tree. The height of the tree is equal to the number of nodes on the longest path from root to a leaf.

null
Given a Binary Tree, print the zigzag traversal of the Binary Tree. Zigzag traversal of a binary tree is a way of visiting the nodes of the tree in a zigzag pattern, alternating between left-to-right and right-to-left at each level.

Given two Binary Trees, return if true if the two trees are identical, otherwise return false.

Given a Binary Tree, print the zigzag traversal of the Binary Tree. Zigzag traversal of a binary tree is a way of visiting the nodes of the tree in a zigzag pattern, alternating between left-to-right and right-to-left at each level.
software development interview question

Given a Binary Tree, perform the boundary traversal of the tree. The boundary traversal is the process of visiting the boundary nodes of the binary tree in the anticlockwise direction, starting from the root.
software development interview question
null
Given a Binary Tree, determine the maximum sum achievable along any path within the tree. A path in a binary tree is defined as a sequence of nodes where each pair of adjacent nodes is connected by an edge. Nodes can only appear once in the sequence, and the path is not required to start from the root. Identify and compute the maximum sum possible along any path within the given binary tree.

Given the Preorder and Inorder traversal of a Binary Tree, construct the Unique Binary Tree represented by them.
software development interview question
null
Given a Binary Tree, determine whether the given tree is symmetric or not. A Binary Tree would be Symmetric, when its mirror image is exactly the same as the original tree. If we were to draw a vertical line through the centre of the tree, the nodes on the left and right side would be mirror images of each other.
software development interview question
null
Given a Binary Tree, convert the value of its nodes to follow the Children Sum Property. The Children Sum Property in a binary tree states that for every node, the sum of its children's values (if they exist) should be equal to the node's value. If a child is missing, it is considered as having a value of 0.

Given a Binary Search Tree and an integer ‘K’. Find and return the ‘K-th’ smallest and ‘K-th’ largest element in the given Binary Search Tree.
software development interview question
null
Given a Binary Tree, design an algorithm to serialise and deserialise it. There is no restriction on how the serialisation and deserialization takes place. But it needs to be ensured that the serialised binary tree can be deserialized to the original tree structure. Serialisation is the process of translating a data structure or object state into a format that can be stored or transmitted (for example, across a computer network) and reconstructed later. The opposite operation, that is, extracting a data structure from stored information, is deserialization.

Given a weighted, directed and connected graph of V vertices and E edges, Find the shortest distance of all the vertices from the source vertex S.
software development interview question
null
The problem is to find the shortest distances between every pair of vertices in a given edge-weighted directed graph. The graph is represented as an adjacency matrix of size n*n. Matrix[i][j] denotes the weight of the edge from i to j. If Matrix[i][j]=-1, it means there is no edge from i to j.
