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 ...

BFS (Breadth First Search) − It is a tree traversal algorithm that is also known as Level Order Tree Traversal. In this traversal we will traverse the tree row by row i.e. 1st row, then 2nd row, and so on.DFS (Depth First Search ) − It is a tree traversal algorithm that traverses the structure to its deepest node. There are three most used methods that are used to traverse the tree using DFS. it goes into depth of each node as the root node and then goes to the next one.Solved for a TreeLet’s find the traversal of a ...

Array is a sequence of elements of same data type. in this problem we are going to consider integer array for solving the problem. in this problem we are going to find sum of Elements found by dividing the element from the element proceeding it.Let’s take a few examples to understand this Problem better −Example 1 −Array : 3 , 5 ,98, 345 Sum : 26Explanation − 3 + 5/3 + 98/5 + 345/98 = 3 + 1 + 19 + 3 = 26We have divided each element with its preceding element and considered only integer parts of the divisions ...

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 ...

A bitset is a dataset that stores multiple boolean values but takes lesser memory space as compared to other data sets that can store a sequence of bits like a boolean array or boolean vector.Bitsets stores the binary bits in a form that takes less memory space, it stores them in compressed from. Accessing any element is same as others i.e. by using its index value i.e. bitset_name[index]. But the indexing of elements in a bitset is reverse. Let’s take an example, for bitset {01101001} the element at 0th index is 1 and so on. So 0’s are at index ... Read More

The matrix probability question Calculates the probability that whether an element will be inside the given matrix after taking N steps and any direction. This means we need to find what is the probability of an element not going out of the scope of the matrix even after moving N positions in any direction.In this problem, we are free to move the matrix element in all four directions (left, right, up, down). And the probability of moving elements is same 0.25 or 1/4.The program will return 0 if the element steps out otherwise not.Example Live Demo#include int isSafe(int x, int ... Read More

_Generic keyword in C is used to define MACRO for different data types. This new keyword was added to the C programming language in C11 standard release. the _Generic keyword is used to help the programmer use the MACRO in a more efficient way.this keyword translate the MACRO based on the type of the variable. let's take an example ,#define dec(x) _Generic((x), long double : decl, \ default : Inc , \ float: incf )(x)The above syntax is how to declare any MACRO as generic for different methods.Let's take an example code, this code will define a MACRO that will ...

In C++ 17, there are introduced two new ways by which a programmer can assign values to a variable or declared them. In this update, elser then the classical way of assigning values to a variable the following two ways to initialise values.Classical methodInitially the assignment operator ‘=’ is used for assignment and declaration of a variable. assignment of a variable using = looks like, datatype variable_name = value;Example, int val = 243;New methodUniform initialisationIn uniform initialisation of variables we do not use the ‘=’ operator. the value is enclosed inside a pair of curly braces ' {} '. Value ... Read More

An adapter pattern is used to convert the interface of a class into an interface that is expected by the client. An adapter helps the programmer to make its classes work together and make sure the user requirement is fulfilled by making incompatible interfaces completable.let's understand a bit more about the adapter pattern. The concept of adapter is taken from the real world. as in the real world We use adapters to connect things that are incompatible with each other. let's take an example, in modern day smartphones the 3.5 mm jack for earphones is missing, so the brands have ...
