Description The problem “Minimum Steps to reach target by a Knight” states that you are given a square chess board of N x N dimensions, co-ordinates of the Knight piece, and the target cell. Find out the minimum number of steps taken by the Knight piece to reach the target …
Problem Statement “Height of a generic tree from parent array” problem states that you are given a tree with n vertices as an array par[0…n-1]. Here every index i in par[] represents a node and the value at i represents the immediate parent of that node. For the root node …
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 …
Given a Binary Search Tree, write an algorithm to find the node with the minimum value in a given binary search tree. Example Input Output 5 Naive Approach A simple approach is to do a tree traversal and find the node with the minimum value among all the nodes. This …
In this problem we have given a binary tree, print its level order traversal in a spiral form. Examples Input Output 10 30 20 40 50 80 70 60 Naive Approach for Level order Traversal in Spiral Form The idea is to do a normal level order traversal using a …
In the smallest multiple of a given number made of digits 0 and 9 only problem we have given a number n, find the smallest number made from digits 0 and 9 that is divisible by n. Assume that the answer will not exceed 106. Examples Input 3 Output 9 …
Problem Description: Given a 2D matrix, the matrix has only 0(representing water) and 1(representing land) as entries. An island in the matrix is formed by grouping all the adjacent 1’s connected 4-directionally(horizontal and vertical). Find the maximum area of the island in the matrix. Assume that all four edges of …
Given a binary tree, print the zigzag level order traversal of its node values. (ie, from left to right, then right to left for the next level and alternate between). Example consider the binary tree given below Below is the zigzag level order traversal of the above binary tree Types …
Given a Binary Tree, connect nodes that are at the same level from left to right. Structure of the Tree Node: A node of the tree contains 4 components which are data(integer value), pointers(next, left and right) of the tree node type. next pointer of a node point towards its …
Given a tree (an acyclic fully connected graph where constituent nodes are connected by bidirectional edges) and a source node. find the level of each node in a tree form source node. It is given that level of a node v with respect to the source is the distance between …
