Count common prime factors of two numbers in C++
We are given the two numbers let’s say x and y and the task is to find the common prime factors between two numbers. Common prime factors can be found by firstly calculating the common numbers between two numbers and after that checking from the list of common factors the one which are prime numbers.For ExampleInput − x = 10 y = 20 Output − Common prime factor of two numbers are: 2 5Explanation − common primes factors between 10 and 20 are 2 and 5 only.Input − x = 34 y = 12 Output − Common prime factor of ...
Read MoreProgram to find remainder when large number is divided by r in C++
In this problem, we are given a string num which is a large number and an integer R. Our task is to create a program to find remainder when large number is divided by r in C++.Problem Description − We need to find the remainder when the number defined by the string is divided by r which is a two-digit number.Let’s take an example to understand the problemInputnum = “123423450942121” r = 54Output7Solution ApproachTo find the remainder, we obviously need to divide the number. But dividing huge numbers is a complex process so to ease up the process, we will ...
Read MoreCount and Sum of composite elements in an array in C++
We are given with an array of positive integers and the task is to calculate the count and sum of the composite elements in the given array.What are composite numbersFrom the given set of integers, the numbers that are not prime are called composite numbers except 1 which is neither composite nor prime instead it’s a unit number. So, it is clearly stated that a number can be either prime or composite except the number 1.The composite upto 100 are given below −4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, ...
Read MoreProgram to find remainder without using modulo or % operator in C++
In this problem, we are given two numbers, N and D. Our task is to create a Program to find remainder without using modulo or % operator in C++.Problem description − We need to find the remainder that will be left after dividing the number N by D. But we cannot use the modulo or % operator for this.Let’s take an example to understand the problemInputN = 53 D = 3Output2Solution ApproachTo find the remainder, a simple approach is to find the number less than N which is the multiple of D. And the substrate the number from N. To ...
Read MoreCount characters in a string whose ASCII values are prime 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 whose ASCII values are prime.The ASCII values of uppercase letters[A-Z] start with 65 till 90 and lowercase letters[a-z] starts with 97 till 122.For ExampleInput string str = ‘Aebg’ Output count is: 2Explanation − The ASCII value for A is 65 which is a non-prime number so it willn’t be counted, e is 101 which is a prime number so it will be counted, b is 66 which is a nonprime number so it willn’t be ...
Read MoreProgram to find root of an equations using secant method in C++
In this tutorial, we will be discussing a program to find the root of an equation using secant method.For this we will be provided with an equation. Our task is to find the roots of that equation using the iterative secant method.Example#include using namespace std; float f(float x) { float f = pow(x, 3) + x - 1; return f; } void secant(float x1, float x2, float E) { float n = 0, xm, x0, c; if (f(x1) * f(x2) < 0) { do { //calculating the intermediate ...
Read MoreCount Hexadecimal Number in C++
We are given a range having start and end and the task is to calculate the count of hexadecimal numbers or alphabets present in the given range.What are Hexadecimal Alphabets?In computer terms, hexadecimal numbers are those numbers that are having base 16 which means the binary digit can be represented in 16-bit. It consists of integer numbers starting from 0-15. Where 10 is represented as A, 11 as B, 12 as C, 13 as D, 14 as E and 15 as F.So, in the below program our task is to find whether the range consists of hexadecimal alphabets or not.For ...
Read MoreProgram to find second most frequent character in C++
In this problem, we are given string str. Our task is to create a Program to find second most frequent character in C++.Let’s take an example to understand the problemInputstr = “abaacabcba”Output‘b’Solution ApproachTo find the character that is second most frequent in the string. We need to maintain a count array chatCount that is used to store the frequency of each character in the string. And then using the array we will find the character with max and secondMax frequency in the array. And display the second most frequent character.Program to illustrate the working of our solutionExample#include #include ...
Read MoreCount all triplets whose sum is equal to a perfect cube in C++
We are given with an array of n integers and the task is to calculate the count all the triplets whose sum is equal to perfect cubeWhat is the perfect cubeA perfect cube is a number which is a cube of any number, like 125 is a cube of 5 so we can say that 125 is a perfect cube. Some of the perfect cube integers are 1, 8, 27, 64, 125….So, according to the problem in the array we have to find and count those triplets (set of 3 values) whose sum is equal to a perfect cube number. ...
Read MoreProgram to find Smallest and Largest Word in a String in C++
In this problem, we are given string str. Our task is to create a program to find Smallest and Largest Word in a String in C++.Problem Description − Here, we have a string we need to find the word whose length is maximum and minimum out of all words in the string. The word is separated using white spaces or null(\0) characters.Let’s take an example to understand the problemInputstr = “Learn Programming at TutorialsPoint”Outputsmallest word = at largest word = TutorialspointSolution ApproachTo find the smallest and largest word, we will find the length of each word by using two indexes, ...
