C++ Program to calculate the Highest Common Factor
The highest Common Factor or Greatest Common Divisor are factors that are maximum and that can divide two or more values without generating any remainder. In this article, we shall discuss a few methods to perform HCF / GCD between two numbers in C++. This is simply a mathematical solution and there are several algorithms present to find GCD. The Euclidean method to find GCD is common. The same algorithm we will use in iterative mode, and recursive mode. Using Iterative method The iterative solution for the Euclidean gcd finding algorithm is shown in the algorithm section. Algorithm ...
Read MoreProgram to check the similarity of given two triangles
In this problem, we will learn to check the similarity of two given triangles, which have many real-world use cases from the viewpoint of a programmer. To construct and manage 2D and 3D models of things, CAD systems are utilized, and one key function is the capability to compare two triangles. For instance, engineers working in design and construction may need to make that the foundational measurements of a building match the blueprint. Engineers can rapidly evaluate whether the angles and sides of the foundation game the layout by utilizing a CAD tool that has a built-in feature to check ...
Read MoreNumber of triangles in a plane if no more than two points are collinear
Let us see how to calculate the number of triangles in a plane with n number of points given, with the constraint that not more than two points are collinear. Computing the number of triangles in a plane with no more than two collinear points is a typical problem in computational geometry, and it is used in computer graphics, image processing, and other areas of computer science. While creating a 2D image from a 3D scene in 3D graphics, for instance, the issue of counting triangles in a plane with no more than two points collinear can come up. The ...
Read MoreDifferent ways to represent N as the sum of K non-zero integers
The problem “Different ways to represent N as the sum of K non-zero integers” has many real-world use cases. Cryptography − In cryptography, specific cryptographic methods are designed using the concept of encoding a number N as the sum of K non-zero integers. Representing an integer N as the sum of K non-zero integers might appear as a subproblem in different optimization issues in the context of optimization methods. Machine learning − In machine learning, feature vectors that depict the distribution of data points can be created by using the problem of representing an integer N as the sum of ...
Read MoreCompute power of power k times % m
Our objective to compute power of power k time % m, with the values of base, k and m provided as input − Look at the image above. Have you ever tried to compute such a problem? Let’s try it. Compute the power of power k times and then find modulo with m. Explanation In this question, x, k, and m are given. Compute ${x^{x{^x{^{^.{^{^.{^{^.}}}}}}}}}$ up to k times and then modulo with m. Let’s understand with an example. Given, x = 2, k = 4, and m = 6 So, Compute $2^{2^{2{^2}}}\:=\:4^{2{^2}}\:=\:16^2\:=\:256$ Then 256 % 6 ...
Read MoreCheck whether an array can fit into another array by rearranging the elements in the array
From the problem statement, we can understand that given two arrays, we have to check whether the first array can fit into the second array. In the real world, there are many instances where we need to check whether an array can fit into another array by rearranging the elements in the array. For a variety of reasons, programmers may need to reorder the items of an array to see if they can fit into another array. Memory management in computer programming is one such reason. When working with huge amounts of data, it is frequently more effective to use ...
Read MoreLevel order traversal with direction change after every two levels(Implementation in C/C++)
Level Order TraversalThis is one of the algorithms that processes or prints all nodes of a binary tree by traversing through depth, starting at the root and moving on to its children and so forth.Example INPUT − OUTPUT − 2 4 7 3 6 11 This task involves printing a binary tree's level order traversal so that the first two levels are printed from right to left direction, and the next two levels from left to right direction, and so on. The challenge is that a binary tree's level order traverse must be ...
Read MoreVieta's Formulas
In mathematics, Vieta’s formulas are the concept of polynomials which relates a polynomial’s coefficients to the sums and products of the roots of the polynomial. Vieta’s formulas can be useful tools for learning relations between the polynomial’s roots without really knowing their numerical value and coefficients of the equation. We will be focusing on the concept of Vieta’s formulas and try to solve some problems using this formula in this article. Vieta’s Formulas The formulas developed by the mathematician Vieta establish the relationship between the sum and product of any polynomial’s roots and its coefficients. Since this formula deals with ...
Read MoreSubsequence of size k with maximum possible GCD
The problem statement says we will be given an array as input and a positive integer K, we need to figure out the maximum possible gcd(greatest common divisor) of a ksized subsequence of an array in this problem. It can be solved using different algorithms to find gcd of the numbers and figuring out the maximum gcd for a k-sized subsequence. Before that we must know about the subsequence of an array. A subsequence of an array is a sequence of numbers from the array not necessarily adjacent numbers in the array but the order of the numbers in the ...

The problem includes printing first m terms of Smarandache-Wellin Sequence where m is any positive integer. We will see the algorithm to print the first m term of Smarandache-Wellin Sequence in C++. But before that we must know about the Smarandache-Wellin sequence. A Smarandache-Wellin sequence is a sequence of Smarandache-Wellin numbers. Smarandache-Wellin numbers are the integers which are formed by concatenation of the consecutive prime numbers. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23…. The first Smarandache-Wellin number of the sequence is 2. The second number of the sequence is 23, which ...
