Problem Statement The problem “Bottom View of a Binary Tree” states that you are given a binary tree and now you need to find the bottom view for the given tree. When we see a tree from the downward direction. The nodes which are visible to us is the bottom …
Problem Statement The problem “Print Right View of a Binary Tree” states that you are given a binary tree. Now you need to find the right view of this tree. Here, right view of the binary tree means to print the sequence as the tree looks when looked from the …
Problem Statement The problem “Find Maximum Level sum in Binary Tree” states that you are given a binary tree with positive and negative nodes, find the maximum sum of a level in the binary tree. Example Input 7 Explanation First Level : Sum = 5 Second Level : Sum = …
Problem Statement The problem “Level order traversal using two Queues” states that you are given a binary tree, print its level order traversal line by line. Examples Input 5 11 42 7 9 8 12 23 52 3 Input 1 2 3 4 5 6 Algorithm for Level Order Traversal …
Problem Statement The problem “Check if the given array can represent Level Order Traversal of Binary Search Tree” states that you are given a level order traversal of the binary search tree. And using the level order traversal of the tree. We need to efficiently find if the level order …
Problem Statement The problem “Number of siblings of a given Node in n-ary Tree” states that you are given an n-ary Tree and a target node. Find the number of siblings of the target node. Assume that node is always present in the tree and the first node is the …
Description The problem “Count the number of nodes at given level in a tree using BFS” states that you are given a Tree (acyclic graph) and a root node, find out number of nodes at L-th level. Acyclic Graph: It is a network of nodes connected through edges which has …
Problem Statement “Maximum depth of binary tree” problem states that you are given a binary tree data structure. Print the maximum depth of the given binary tree. Example Input 2 Explanation: Maximum depth for the given tree is 2. Because there is only a single element below the root (i.e. …
In binary tree to binary search tree conversion problem, we have given a binary tree convert it to Binary Search Tree without changing the structure of the tree. Example Input Output pre-order : 13 8 6 47 25 51 Algorithm We do not have to change the structure of the …
Given the level order traversal of a Binary Search Tree, write an algorithm to construct the Binary Search Tree or BST from ITS given level order traversal. Example Input levelOrder[] = {18, 12, 20, 8, 15, 25, 5, 9, 22, 31} Output In-order : 5 8 9 12 15 18 …
