Sometimes, we require to take the date from the users' string format. So, users can make mistakes while entering the date value into the input field. So, we need to validate the date string at our end in the application code. Below, we will learn various solutions to validate the date in ReactJs. Use the Validator NPM Package The Validator is an NPM package that contains various methods to validate strings. For example, it contains the isDate() method, and we can validate the date string with any delimiter separated. Also, it contains the methods to validate the email and phone ... Read More
We will learn to trim white spaces from the input in ReactJS. Sometimes, users add unnecessary space at the start or end of the input by mistake. So, as a developer, we need to check if the input string contains the white space at the start or end. If we find white spaces in the input, we should trim it; Otherwise, it can cause issues. For example, we need to store the email in the database, and while registering the email, the user has also added the white spaces by mistake, and we stored the email in the database with ...

ReactJS allows us to define a state object for every component. In the state object, we can add the different variables as a property of the state object. After that, we can use the state variables inside the component to render or perform other operations in the component. This tutorial will teach us to create a state object for the component and update it with various values. Use the setState to update the object in ReactJS The state object is used with the class components in ReactJS. Using the setState() method, we can update the state object. Syntax ... Read More
Partitioning a string into palindromic strings of at least length 2 with every character present in a single string is a challenging problem in computer science. The task is to take a string and divide it into multiple substrings, each consisting of at least two characters and containing every character of the original string only once. The objective is to determine if each substring is a palindrome or not. In this tutorial, we will provide a solution to this problem using C++. We will discuss the algorithm and the code implementation step by step, along with providing two test ... Read More
Modifying a string by replacing characters with alphabets whose distance from that character is equal to its frequency is an intriguing problem that involves manipulating strings in a unique way. The task is to take a given string as input and replace each character in the string with an alphabet that is at a distance equal to the frequency of that character in the string. For instance, if the character 'a' appears three times in the string, it would be replaced by an alphabet that is three positions away from 'a' in the English alphabet. This problem presents an interesting ... Read More
Checking if a Binary String contains A pairs of 0s and B independent 0s or not is a common problem encountered in computer science, particularly in the field of algorithms and data structures. The problem statement is quite simple and plays a significant role in various fields, such as cryptography, network security, and machine learning. In this tutorial, we will discuss a solution to this problem using C++. We will first provide an overview of the approach starting with defining the problem statement with some examples and, then we will dive into the implementation details. So let’s get started! ...

Modifying string by sorting characters after the removal of characters whose frequency is not equal to the power of 2 is a popular problem in the field of computer programming, particularly in the context of competitive programming. The problem involves taking a string as input and modifying it by removing characters whose frequency is not a power of 2, and then sorting the remaining characters in lexicographically increasing order. In this tutorial, we will provide a detailed solution to this problem using the C++ programming language. We will start by discussing the problem statement in greater detail, exploring the ...

Checking if any pair of consecutive 1s can be separated by at most M 0s by circular rotation of a Binary String is a common problem in computer programming and binary manipulation. The task is to determine whether a given binary string can be rotated in a circular manner such that any pair of consecutive 1s in the string can be separated by at most M 0s. This problem arises in various applications, such as image processing, data compression, and information retrieval. In this tutorial, we will delve into the intricacies of this problem statement and provide a solution ... Read More
Powerful software like Microsoft Excel is frequently used for data management, analysis, and reporting. You can get into instances where you need to drop the middle initial from a person's whole name while working with large databases or lists of names. When you need to standardise the names for additional analysis or when you have a mix of names with and without middle initials, for example, this can be helpful. These techniques are simple to apply and adaptable to your unique needs, whether you are a novice or seasoned Excel user. Let's get started and investigate the many methods for ... Read More
Powerful spreadsheet programmes like Microsoft Excel are frequently used for data analysis, charting, and visualisation. You can find yourself including different forms, such as lines, arrows, and other objects, when designing intricate Excel worksheets or charts in order to improve the overall presentation and data comprehension. In this article, we'll examine the simplest method for getting the job done. To finish the task, we'll use the locate and select function. You might need to modify or remove some parts as your Excel file develops and your needs change. Removing line forms in Excel can be a regular activity when you ... Read More
