Local Class in C++
A class declared inside a function is known as a local class in C++ as it is local to that function, where its scope is limited to that function. Syntax Here the syntax for a local class is given as follows. #include using namespace std; void func() { class LocalClass { }; } int main() { return 0; } In the above syntax, func() is a function, and class LocalClass is defined inside the function. So, it is known as a local class. A local class name can only be used in its function and not outside it. Also, the ...
Read MoreJava program to get number of elements with odd factors in given range
In this article, we will learn how to count the number of elements with odd factors (i.e., perfect squares) in a given range using Java. Perfect squares have odd divisors, and we can calculate them by counting the perfect squares in the specified range. Problem StatementGiven a range defined by a lower and upper bound, write a Java program to calculate how many numbers in this range have odd factors (i.e., perfect squares).Input Lower Range: 55Upper Range: 1000Output The number of elements with odd factors between 55 and 1000 is: 24 Steps to calculate the number of elements with ...
Read MoreJava program for minimum move to end operations to make all strings equal
In this article, we will learn how to solve a problem where we are given an array of strings, and we need to make all strings equal by rotating them. This can be done by performing left rotations on the strings. We need to count the minimum number of operations required to do this. If it is impossible to make the strings equal, the output should be -1. Problem statement We have given an array containing n strings. All strings are permutations of each other. We need to count the total number of minimum operations required to make all strings ...
Read MoreNumber of pairs with maximum sum in C++
We need to find a number of all the pairs that has the maximum sum, In a given array of integers. A pair consists of two numbers, and the sum is simply the result of adding them. We will see multiple solutions to this problem, starting with a naive (brute force) approach and moving to more optimized solutions. Below is the list of approaches we will cover in this article: Brute Force approach using two loops Max Sum Pairs with Sorting ...
Read MoreNatural Numbers in C++ Program
In this article, we will cover C++ programs to work with natural numbers. we use natural numbers in various operations, such as indexing arrays, performing loops, and validating user input. we will also write code to demonstrate how natural numbers can be used for these purposes in C++. Natural Numbers are a set of positive numbers, starting from 1 and going to infinity. natural numbers are: 1, 2, 3, 4, 5... etc In C++, understand concepts like conditions, loops, and how we store and manipulate variables. We will provide everything you need to know about natural numbers along with programs. ...
Read MoreJava program to find the number occurring odd number of times
In this article, we will learn how to find the number in an array that appears an odd number of times using Java. By looping through the array and counting occurrences of each number, the program will detect and return the one with an odd frequency. Problem Statement Given an array identify the integer that occurs an odd number of times. Below is the demostration of the same − Input 34, 56, 99, 34, 55, 99, 90, 11, 12, 11, 11, 34 Output The number that occurs odd number of times in the array is 34 Steps to find the number occurring ...
Read MoreNearest 1 in a binary matrix in C++
In this article, we will show you how to find the minimum distance from each cell in a binary matrix to the nearest cell that contains the digit 1. We will see brute force as well as optimized approaches. Problem Statement Given a binary matrix, our task is to calculate the minimum distance for each cell to the nearest cell that contains the value 1, and if the current cell itself has 1 as a value, the distance will be 0. If the input matrix is as follows - 0 0 1 1 1 0 0 0 0 The ...
Read MoreLongest double string of a Palindrome
A contiguous sequence of characters, consisting of uppercase, lowercase, repetitive, or unique alphanumeric characters, forms a C++ string. Each string has a unique length, which may be either odd or even in nature. Longest Double String of a Palindrome A Palindromic string is a sequence of characters that reads the same from both the beginning and the end. In other words, characters at equivalent positions from the start and end have no difference. These palindromes can either have an even length or an odd length. The odd-length palindrome features a middle character separating the two equivalent halves. In this article, ...
Read MoreJava program to print matrix in Z form
In this article, we will learn to print a matrix in a "Z" pattern in Java. It starts from the top-left corner, moves horizontally across the top row, then diagonally down through the center, and finally across the bottom row. This pattern creates a "Z" shape with selected elements from the matrix. Problem Statement Write a program in Java to print a matrix in Z form. Input my_arr[][] = { { 34, 67, 89, 0}, { 0, 1, 0, 1 }, { 56, 99, 102, 21 }, {78, 61, 40, 99}} Output The matrix is34 67 89 0 0 99 ...
Read MoreJava program to print first letter of each word using regex
In this article, we will understand how to print the first letter of each word using regex. A regular expression is a sequence of characters that forms a search pattern. A regular expression can be a single character or a more complicated pattern. A regular expression helps you match or find other strings or sets of strings, using a specialized syntax held in a pattern. They can be used to search, edit, or manipulate text and data. Problem Statement Write a program in Java to print the first letter of each word using regex. Below is a demonstration of the same ...
