Program to find sum of 1 + x/2! + x^2/3! +...+x^n/(n+1)! in C++
In this problem, we are given two values x and n that corresponds to the given series. Our task is to create a program to find sum of 1 + x/2! + x^2/3! +…+x^n/(n+1)! in C++.Problem description − we need to find the sum of series based on the given values of x and n. In the series, every other term differs from the previous term by x/i for ith term.Let’s take an example to understand the problemInputx = 6, n = 4Output29.8ExplanationThe sum of the series is1 + 6/2 + 36/6 + 216/24 + 1296/120 = 29.8Solution ApproachTo find ...

In this problem, we are given an array arr[] of n integer values. Our task is to create a Program to find sum of elements in a given array in C++.Program Description − For the given array, we will add up all elements and return the sum.Let’s take an example to understand the problemInputarr[] = {3, 1, 7, 2, 9, 10}Output32ExplanationSum = 3 + 1 + 7 + 2 + 9 + 10 = 32Solution ApproachTo find the sum of elements of the array, we will traverse the array and extract each element of the array and add them to ...
Read MoreProgram to find sum of first n natural numbers in C++
In this tutorial, we will be discussing a program to find sum of first n natural numbers.For this we will be provided with an integer n. Our task is to add up, find the sum of the first n natural numbers and print it out.Example#include using namespace std; //returning sum of first n natural numbers int findSum(int n) { int sum = 0; for (int x=1; x
Read MoreProgram to find sum of harmonic series in C++
In this problem, we are given three numbers a, d, and n. Our task is to create a program to find sum of harmonic series in C++.Harmonic progression is a series whose inverse will be an arithmetic progression. I.e. if for a harmonic progression A1, A2, A3.. An, there is an arithmetic progression 1/A1, 1/A2, 1/A3.So, a general HP is1/a, 1/(a+d), 1/(a+2d), … 1/(a + nd)Where 1/a is the first term. And d is the common difference of the reversed AP.Problem Description − Here, we will be given the first term a, common difference d, and the number of terms ...

Read MoreProgram to find the angles of a quadrilateral in C++
In this problem, we are given a value d, which is the common difference of AP. This AP is all the angles of a quadrilateral. Our task is to create a program to find the angles of a quadrilateral in C++.Problem Description − Here, the angles of the quadrilateral are in the form of an AP with common difference d. And we need to find the angles.Let’s take an example to understand the problemInputd = 15Output67.5, 82.5, 97.5, 112.5ExplanationFirst angle is x Second angle is x + 15 Third angle is x + 30 Four angle is x + 45Sum ...
Read MoreCreate Maximum Number in C++
Suppose we have two arrays of length m and n with digits 0-9 representing two numbers. We have to create the maximum number of length k that is less than m + n from digits of the two. We have to keep in mind that the relative order of the digits from the same array must be preserved. We have to find the array of the k digits. So if the inputs are like [3, 4, 7, 5] and [9, 1, 3, 5, 8, 4], and k = 5, then the answer will be [9, 8, 7, 5, 4].To solve ...
Read MoreCount of Range Sum in C++
Suppose we have an integer array nums, we have to find the number of range sums that lie in range [lower, upper] both inclusive. The range sum S(i, j) is defined as the sum of the elements in nums from index i to index j where i ≤ j.So if the input is like [-3, 6, -1], lower = -2 and upper = 2, then the result will be 2, as the ranges are [0, 2], the sum is 2, [2, 2], sum is -2.To solve this, we will follow these steps −Define a function mergeIt(), this will take array ...

Suppose we have some envelops, these envelops has height and width values as pairs. We can put one envelop into another one if the height and width of second envelop both are smaller than the height and width of the first one. So, what will be the maximum number of envelops that we can put inside other. So, if the inputs are like [[5, 5], [6, 4], [6, 8], [2, 3]], then the output will be 3, as smallest envelop is [2, 3], then [5, 5], then [6, 8].To solve this, we will follow these steps −sort the array v ...
