Program to find N-th term of series 3, 6, 18, 24, ... in C++
In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 3, 6, 18, 24, … in C++.Problem Description − To find the Nth term of the series −3, 6, 18, 24, 45, 54, 84 … N TermsWe need to find the general formula for the given series.Let’s take an example to understand the problem, Input − N = 10Output − 150Solution Approach:To find the general term of the series, we will first observe the series and check all the possible generalizations of the series. Like, 3 is common ...
Read Moreset vs unordered_set in C++ STL(3)
In this article, let us understand what is set and unordered_set in C++ STL and thereby gain knowledge of difference between them.What is set?A set is an Associative container which contains a sorted set of unique objects of type Key. Each element may occur only once, so duplicates are not allowed. A user can create a set by inserting elements in any order and the set will return a sorted data to the user which means set contains definition for sorting the data which is abstracted from the user.The main reasons when set can be used are −When sorted data ...
Read MoreImage Smoother in C++
Suppose we have a 2D matrix M representing the gray scale of an image, we have to design a smoother to make the gray scale of each pixel becomes the average gray scale (rounding down) of all the 8 surrounding pixels and itself. If a cell has less than 8 surrounding cells, convert all possible pixels.So, if the input is like111101111then the output will be000000000To solve this, we will follow these steps −R := row count of MC := column count ofDefine an array d = { -1, 0, 1 }Define one 2D array res of size (R x C)for ...
Read MoreProgram to find N-th term of series 3, 12, 29, 54, 86, 128, 177, 234, ..... in C++
In this tutorial, we will be discussing a program to find N-th term of series 3, 12, 29, 54, 86, 128, 177, 234, …..For this we will be provided with a number. Our task is to find the term for the given series at that particular position.Example#include #include using namespace std; //calculating nth term of given series int nthTerm(int n) { return 4 * pow(n, 2) - 3 * n + 2; } int main() { int N = 4; cout

Read MoreMaximum area of rectangle possible with given perimeter in C++
Given a perimeter of a rectangle, the task is to find the maximum area of the rectangle with that given perimeter.A rectangle is a type of parallelogram whose opposite sides are equal and parallel.The perimeter of a rectangle is the sum of all sides of a rectangle; we can also say perimeter is the total distance of the outside of the rectangle.The formula to find the perimeter of a rectangle is − Length + Breadth + Length + Breadth or 2(Length + Breadth)Whereas the area of a rectangle is the size of the rectangular object. The formula for finding the ...
