Array is a data structure that stores multiple elements of the same data type. It can store entire set of values at once. But its length needs to be defined beforehand.In this sum array puzzle, we are given an array A1 of a definite size say n. In order to solve this puzzle, we will create an array called S1 that stores the sum of all elements of the array except the element whose position is being used. For example, if S1[3] is being calculated then we will find the sum of all elements of A1 except the element at ... Read More

A program to shutdown the system works on the operating systems like windows, linux or macOS. To shut it off and close all opened applications.What shut down or power off means?Shut down or Power off a computer means removing power from a computer's main components in an organised prescribed way and turning off all the works that are done by the computer i.e. all applications and processings are shut off. After a computer is shut down, the main components such as CPU, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, ... Read More

Find the area of largest Triangle inscribed in a hexagon we need to learn these figures are and how 1 is inscribed inside other.Triangle is a closed figure with 3 sides which may be equal or different size.Hexagon is a closed figure with 6 sides which may be equal or unequal in size.A triangle inscribed inside a hexagon has all its vertices touching vertices of hexagon. So, the sides of the triangle can be treated as diagonals of a regular hexagon. The hexagon considered here is a regular hexagon, which leads to make the largest triangle an Equilateral triangle.Let’s derive ... Read More

Circumcircle of Triangle A circumcircle of a triangle is a circle that passes through all the vertices of a triangle. The center of circumcircle is known as the circumcenter, which is an intersection of all the perpendicular bisectors of the triangle. The radius is known as the circumradius and is denoted by R. Formula to Calculate Area of Circumcircle of Triangle You can use the formula given below to calculate the area of the circumcircle of a triangle: $$ \frac{\pi (abc)^2}{16K^2} $$ where, a, b, and c are the sides of ...

For learning about the angle between two planes in 3D, we need to learn about planes and angles.Plane is a two-dimensional surface that extends to infinity.Angle is the space in degrees between two lines and surfaces which intersect at a point.So, in this problem we need to find the angle between two 3D planes. For this we have two planes that intersect each other and we need to find the angle at which the are intersecting each other.To calculate the angle between two 3D planes, we need to calculate the angle between the normal's of these planes.Here, we have two ...

Bellman Ford Algorithm is dynamic programming algorithm which is used to find the shortest path of any vertex computed from a vertex treated as starting vertex. this algorithm follows iterative method and continuously tries to find shortest Path. The Bellman Ford Algorithm on weighted graph.this algorithm was proposed by Alphonso shimbel in 1955. The algorithm has revisions by Richard Bellman and Lester Ford in the year 1956 and 1958, due to this algorithm was named Bellman Ford Algorithm. This algorithm was also revised by Eward F. Moore in 1957, which made its name to Bellman-Ford-Moore Algorithm.This algorithm is better as ... Read More

C++ programming language defines a container in c++ standard Template Library named as bitset. This bitset container is used in order to work on elements at the bit level i.e. each bit of the variable the bits i.e. binary conversion of the given value.1. Bitset is like an string − Bitset is a container of bits ( only 0 and 1 are valid ). You can create a bitset with any set of bits specified by start index value of the bitset and the number of elements that are considered i.e. you can create a bitset with 2 elements starting ...

The algorithm to find the maximum number of points that can be enclosed in a circle of a given radius. This means that for a circle of radius r and a given set of 2-D points, we need to find the maximum number of points that are enclosed (lying inside the circle not on its edges) by the circle.For, this is the most effective method is the angular sweep algorithm.AlgorithmThere are nC2 points given in the problem, we need to find the distance between each of these points.Take an arbitrary point and get the maximum number of points lying in ...

A set is a data structure that is used to store distinct values (meaning no two elements can have the same value) in ascending or descending order. Set for User-defined Data TypesWe can directly use sets for built-in data types, but for user-defined data types, values cannot be directly stored, because a set compares the elements to maintain order, but for user-defined data types such as array or struct, the compiler will not be able to perform a comparison between them. The set container is defined under the header file. So to use user-defined datatypes into a stack, we ... Read More

The basic_string c_str function that returns a pointer to an array of characters that is terminated using null character. It is an inbuilt method that has the value of a string that has null character termination.Syntax to define a c_str function in C++ −const Char ptr* c_str() constAbout the functionIt is an inbuilt method for the c++ STL library. No parameters can be passed to the method. It returns a char pointer. This pointer points to NULL terminated character array.Example Live Demo#include #include using namespace std; int main() {    string s = "I Love Tutorials Point";    int ... Read More
