Given the binary tree, the function must find out the level order traversal of a tree line by line.Level order traversal: Left Root Right, which means firstly print left child of a node than the value of a root and then go to the right child but here we have ... Read More

Given an array of nxn size, the program must print the elements of an array in a snake pattern starting from the last column that means from arr[0][n]th element without doing any changes to their original locations.ExampleInput: arr[]= 100 99 98 97    93 94 95 96    92 91 ... Read More

Given an integer n, the task is to print the numbers who consist only 0’s and 1’s and their sum is equal to the integer n.The numbers which contain only zeros and ones are 1, 10, 11 so we have to print all those numbers which can be added to ... Read More

Given with an array of integer elements, the task is to remove the duplicate values and print the distinct elements in sorted manner.Given below is an array that stores integer type values in the fashion 4, 6, 5, 3, 4, 5, 2, 8, 7 and 0 now, the result will ... Read More

We have to print the data of nodes of the linked list at the given index. Unlike array linked list generally don’t have index so we have to traverse the whole linked list and print the data when we reached a particular.Let’s say, list contains the nodes 29, 34, 43, ... Read More

We are given an positive integer n and make a spiral matrix of n x n, with only using O(1) extra space in clockwise directionSpiral matrix is a matrix that works like a spiral which will start from the origin of a circle and rotates in clockwise fashion. So the ... Read More
