Suppose you are given an array and you have to find the total count of ordered pairs formed such that Ai & Aj = 0. You are given an array A[A1, A2, A3, …An]. You have to find ordered pairs of Ai and Aj such that their bitwise AND operation ... Read More

In this article, we will learn about stepping numbers. We will find the possible number of n digit numbers which are also stepping numbers using several C++ techniques. We will also discuss about the most space optimized solution. Let’s first discuss about stepping numbers. These are such numbers which have ... Read More

Suppose you have a given number N. Now, you want to find those numbers of N digit which do not contain 9. This question can be solved by permutation and combination mathematically. In this article, we will find such numbers and count them using C++. Suppose you have to find ... Read More

Binary language is the language of the computers. So, every integer, character or symbols needs to be converted into binary system and vice versa. There is binary representation to all high-level language. In this article, we will discuss about the binary representation of integers. Also, we will find the mismatching ... Read More

A binary tree is a data structure in which each node can have two children (at most). These children are known as left and right child respectively. Suppose we are given a parent array representation using which you have to a create a binary tree. The binary tree may have ... Read More

A full binary tree is a special type of binary tree in which all the parent nodes either have two or no children. In data structures, these kinds of trees are considered as balanced and organized representation. Full binary trees may have a unique feature where each of the parent ... Read More

Imagine a prisoner (or thief) wants to escape from a jail. In order to do so, he needs to cross N number of walls of varying lengths. He can climb X feet for each jump. But, since the walls are slippery, he falls down by Y feet after each jump. ... Read More

In this article, we will discuss the possible solution of an exciting analytical question of how many jumps are required to reach a point (d, 0) from the origin in a 2D plane where you have been specified fixed length of jumps. We will use the fixed length of jumps ... Read More
