The task is to print the reverse of a given linked list by using recursive function. The program must print the reverse but not reverse the list that means the order of the nodes remains the sameHere, the program will move head pointer containing the address of a first node ... Read More

According to the problem we are given an array of n positive integers, we have to find a pair with maximum AND value from the array.ExampleInput: arr[] = { 4, 8, 12, 16 } Output: pair = 8 12 The maximum and value= 8 Input:arr[] = { 4, 8, ... Read More

The task is to print the right nodes of a given binary tree. Firstly user will insert data for creating a binary tree and than print right view of the tree so formed.The above diagram showcase the binary tree created with the nodes 10, 42, 93, 14, 35, 96, 57 ... Read More

The program should print the middle level of a binary tree e.g. if there are 4 levels in a binary tree than the program must print the level 2 nodes but the demand here is to calculate the level without finding the height.Perfect binary tree is a tree in which ... Read More

Given a string in which we have to check that the length of the longest prefix which is also a suffix of the string like there is a string “abcab” so here “ab” is of length 2 and is the longest substring with same prefix and suffix.ExampleInput: str[] = { ... Read More

The task involves printing leaf nodes of a binary tree at given level k which is specified by the user.Leaf nodes are the end nodes whose left and right pointer is NULL which means that particular node is not a parent node.ExampleInput : 11 22 33 66 44 88 77 ... Read More

The task is to print the left nodes of a given binary tree. Firstly user will insert data hence generating binary tree and than print left view of the tree so formed.Every node can have at most 2 child so here the program must traverse only the left pointer associated ... Read More

Given an array arr[m] with m number of integers and n, which is the value to be added in an array and r queries are given with some start and end. For each query we have to add value n from the start till the end of the limit in ... Read More
