Count characters at same position as in English alphabets in C++
We are given a string of any length containing both uppercase and lowercase letters and the task is to compute the count of those characters that are at the same position as in english alphabets.For ExampleInput − String str = eBGD Output − Count is: 2Explanation − B and D are the characters that lie in the same order in english alphabets as B comes at second position and D comes at fourth position.Input − String str = Abcdeizxy Output − Count is: 5Explanation − A, B, C, D and E are the characters that lie in the same order ...
Read MoreCount characters with same neighbors in C++
We are given a string with, let’s say, str and the task is to compute the count of characters in a string str having the same neighbors and that will include both left and right side of a character in a string. Also, in this scenario the first and last character in a string will always be considered as they have only one adjacent character.For ExampleInput − string str = “poiot” Output − count is 3Explanation − In the given string characters p, t and i are having the same neighbors so the count will be increased to 3.Input − ...
Read MoreCount number of digits after decimal on dividing a number in C++
We are given two integer numbers let’s say num1 and num2 and the task is to divide the num1 with num2 and calculate the count of digits after decimal on dividing these given numbers.For ExampleInput − num1 = 2, num2 = 5 Output − count is 1Explanation − when we divide 2 with 5 i.e. ? = 0.4, so digits after decimal is 1 therefore count is 1.Input − num1 = 2, num2 = 0 Output − Floating point exception (core dumped)Explanation − when we divide any number with 0 it will return an error and terminate the program abnormally.Input ...
Read MoreCount elements in a vector that match a target value or condition in C++
We are given a vector and the task is to calculate the count of those elements in a vector that matches a target value or condition.Vectors are sequence containers that can change size. Container is an object that holds data of the same type. Sequence containers store elements strictly in linear sequence.Vector stores elements in contiguous memory locations and enables direct access to any element using subscript operator []. Unlike arrays, vectors can shrink or expand as needed at run time. The storage of the vector is handled automatically.To support shrink and expand functionality at runtime, vector containers may allocate ...
Read MoreCount number of bits changed after adding 1 to given N in C++
We are given a number let’s say num and the task is to calculate the total number of bits changed when 1 is added to a number.Binary representation of a number is done by converting the given number into the form of 0’s and 1’s and it is done by various methods. In one method, we calculate the LCM of a given number by 2 and if a reminder is other than 0 then the bit is set to 1 else it will be set to 0.Addition table for bits are0 + 1 = 1 1 + 0 = 1 ...

In this problem, we are given a number N. Our task is to create a Program to find N-th term of series 3 , 5 , 21 , 51 , 95 , … in C++.Problem Description − To find the Nth terms of the series −3, 5, 21, 51, 95, 153, … N-TermsWe need to find the general formula of the series, which is a quadratic equation (based increase in the series).Let’s take an example to understand the problem, Input − N = 6Output − 153Solution Approach:To solve the problem, we will find the general formula for the nth term ...
Read MoreProgram 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 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
