Check if substrings from three given strings can be concatenated to form a palindrome
Palindromes are a fascinating topic in computer science and programming. A palindrome is a word, phrase, number, or other sequences of characters that read the same forward and backward, ignoring spaces, punctuation, and capitalization. In this article, we will investigate a unique problem: how to determine if substrings from three given strings can be concatenated to form a palindrome. This problem is a common interview question and can be solved using various techniques, including string manipulation, hashing, and dynamic programming. Problem Statement Given three strings, the task is to check if it's possible to select substrings from each of the ...
Read MoreCheck if given number contains only “01” and “10” as substring in its binary representation
In this article, we delve into an interesting problem from the world of binary string manipulation: "Check if a given number contains only '01' and '10' as substrings in its binary representation". This problem challenges us to verify whether a number's binary representation contains only the substrings '01' and '10'. We'll discuss the problem in detail, offer a C++ code implementation, and illustrate the concept with an example. Understanding the Problem Statement Given a number, the task is to check if its binary representation contains only '01' and '10' as substrings. In other words, we need to verify if the ...
Read MoreCheck if characters of each word can be rearranged to form an Arithmetic Progression (AP)
In this article, we will discuss how to check if the characters of each word in a given string can be rearranged to form an Arithmetic Progression (AP). We will also implement the solution in C++ and provide an example to illustrate the working of the code. Arithmetic Progression (AP) An Arithmetic Progression (AP) is a sequence of numbers in which each term after the first is obtained by adding a constant d to the preceding term. The constant d is called the common difference. For example, the sequence 1, 3, 5, 7, 9 is an Arithmetic Progression with common ...
Read MoreCheck if characters of a string can be made non-decreasing by replacing ‘_’s
In this article, we'll delve into an intriguing problem in the field of string manipulation: how to check if the characters of a given string can be made non-decreasing by replacing '?' characters. This problem provides an excellent opportunity to hone your skills in string manipulation and condition checking in C++. Problem Statement Given a string consisting of alphabetic characters and question marks (?), determine whether the characters can be made non-decreasing by replacing the '?'s. The non-decreasing condition means that for every two adjacent characters in the string, the ASCII value of the second character is not less than ...
Read MoreCheck if all strings of an array can be made same by interchanging characters
In this article, we will explore the problem of checking whether all strings of an array can be made the same by interchanging characters. We will first understand the problem statement and then investigate both the naive and efficient approaches to solve this problem, along with their respective algorithms and time complexities. Lastly, we will implement the solution in C++. Problem Statement Given an array of strings, determine if all strings can be made the same by interchanging characters. Naive Approach The naive approach is to sort the characters of each string in the array and then compare each sorted ...
Read MoreCheck if a string represents a hexadecimal number or not
In computer science, hexadecimal is a base-16 number system. It uses 16 distinct symbols, including the ten decimal digits from 0 to 9 and the six letters A, B, C, D, E, and F to represent numbers from 0 to 15. In this article, we will discuss how to check if a string represents a hexadecimal number or not. Problem Statement Given a string, the task is to check if it represents a valid hexadecimal number or not. Approach We can solve this problem by iterating over the characters in the string and checking if they belong to the set ...
Read MoreCheck if a string can be split into two substrings with equal number of vowels
Welcome to another in-depth guide on a fascinating problem-solving topic in C++. This time, we will be tackling the problem of determining if a string can be divided into two substrings, each containing an equal number of vowels. This problem is an excellent exercise for honing your skills in string manipulation and vowel counting. Problem Statement Given a string, our objective is to determine if it can be partitioned into two non-empty substrings such that both substrings have an equal number of vowels. The vowels in the English alphabet are 'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'. ...

The .NET Framework, a software framework developed by Microsoft, is a platform for building various types of applications. From Windows-based applications to web-based applications and services, the .NET Framework provides a large ...
Read MoreUnderstanding actionPerformed and ActionListener
In the realm of Java programming, the actionPerformed method is a central aspect of handling event-driven programming concepts. It is part of the ActionListener interface and helps manage user interactions with GUI components. In this article, we will explore how to utilize the actionPerformed method from another Java class, enhancing the modularity and readability of your code. Understanding actionPerformed and ActionListener Before we proceed, let's delve into what action Performed and Action Listener are. The Action Listener interface is part of the java.awt.event package. It includes the action Performed method, which is triggered when an action event occurs, such as ...
Read MoreWorking with UDP DatagramSockets in Java
Introduction Networking is a critical component of modern software development. In Java, one of the ways we can establish network communication is by using sockets. While most are familiar with stream-oriented, connection-based TCP sockets, this article focuses on the connectionless, packet-oriented UDP DatagramSockets and how to work with them effectively. Understanding UDP and DatagramSockets User Datagram Protocol (UDP) is one of the core protocols in the Internet Protocol Suite. Unlike TCP, it is connectionless and does not guarantee delivery, order, or error-checking of data packets. However, it is faster and more efficient for lightweight or time-sensitive applications In Java, the ...
