The Pythagorean primes are prime numbers that can be represented in the form 4n + 1, where n is a non-negative integer. These primes have a special property as they can be expressed as the sum of two square numbers. In other words, a prime number p is called ... Read More

The Quartan primes are prime numbers that can be represented as x^4 + y^4. Where x, y > 0. Some Quartan prime numbers are {2, 17, 97, …}.In this article, we will learn how to check whether a number is Quartan Prime or not in C++. Consider the following input ... Read More

The Hankel matrix is a square matrix, in which each ascending skew-diagonal or anti-diagonal (from top-right to bottom-left) elements are constant. For example a matrix name M with size 5x5 is given below − ... Read More

In a statically typed language such as C++, type specifiers are keywords that are used to define the type of data that given variables will hold. There are two types of type specifiers: built-in and user-defined type specifiers. Built-in Type SpecifiersThe built-in type specifiers are the basic and predefined data types provided by ... Read More

4SUM ProblemThe 4Sum is one of the problem variations in which we need to find the number of quadruplets present in the array such that their sum is equal to the given target. We are given an array of n integers called nums and a target value, and we have ... Read More
