Our task is to create a program to find N-th term of series 1 4 15 24 45 60 92... in C++.Problem description − To find the nth term of the series −1, 4, 15, 24, 45, 60, 92, 112 … N termsWe will find the general formula for the series.Let’s take an example to understand the problem, Input − N = 6Output − 60Solution Approach, The general term of the series is based on whether the value of N is even or odd. This type of series is a bit ... Read More

We are given a number let’s say num and the task is to calculate the total number of bits changed when 1 is added to a number.Binary representation of a number is done by converting the given number into the form of 0’s and 1’s and it is done by various methods. In one method, we calculate the LCM of a given number by 2 and if a reminder is other than 0 then the bit is set to 1 else it will be set to 0.Addition table for bits are0 + 1 = 1 1 + 0 = 1 ...

We are given a number let’s say, num and the task is to calculate the count of binary strings that can be formed through the given number num containing only o’s and 1’s.Binary Number System is one the type of Number Representation techniques. It is most popular and used in digital systems. Binary system is used for representing binary quantities which can be represented by any device that has only two operating states or possible conditions. For example, a switch has only two states: open or close.In the Binary System, there are only two symbols or possible digit values, i.e., ... Read More

We are given a binary tree and the task is to calculate the count of full nodes available in a binary tree using iterative and recursive approach. Full nodes are those nodes who have both the children and no child is null. Note that in full nodes we consider nodes with exactly two children.Binary Tree is a special data structure used for data storage purposes. A binary tree has a special condition that each node can have a maximum of two children. A binary tree has the benefits of both an ordered array and a linked list as search is ... Read More

We are given a binary tree and the task is to calculate the count of half nodes available in a binary tree using iterative and recursive approach. Half nodes are those nodes who have only one child and another child is null. Note that in half nodes we don't consider leaf nodes.Binary Tree is a special data structure used for data storage purposes. A binary tree has a special condition that each node can have a maximum of two children. A binary tree has the benefits of both an ordered array and a linked list as search is as quick ... Read More
