HTML login forms are essential components of websites, giving clients a secure way to access limited content or perform verified activities. They serve as the front-end interface where clients input their accreditations, such as usernames and passwords, to get to particular assets. HTML login forms play a significant role in client confirmation and information security. In any case, they are too helpless to different hacking procedures in the event that they are not legitimately secured. Understanding the centrality of securing login forms is fundamental to defending client information and avoiding unauthorized access. Executing vigorous security measures, such as secret ...

The secret to making a dynamic and engaging website is the integration of HTML and JavaScript, A skill important for the developers. The static web pages of HTML are no doubt popular and a stepping stone for beginners, but dynamic and engaging web pages are the ones users prefer. To be able to interact with the website and consume its content is an experience only dynamic web pages can provide. Integration of JavaScript code into an HTML page is a vital skill for web developers. JavaScript is a potent scripting language that allows developers to add dynamic functionality and interaction ...

In this problem, we need to find the maximum length of the subsequence containing the single character by increasing the multiple characters by, at most, k times. We can use the sliding window approach to solve the problem. We can find the maximum length of any window to get the result after sorting the string. Problem statement – We have given string str containing lowercase alphabetical characters. Also, we have given the positive integer k. After performing the at most k increment operations with multiple characters of the given string, we need to find the maximum length of the ... Read More
In this problem, we need to generate a lexicographically smallest string using the first K characters of alphabets so that it doesn’t contain any repeated substring. We can generate a string so that all substrings of length 2 are unique. So, if all substrings of length 2 are unique, all substrings of length 3 or more are also unique. Problem statement – We have given a positive integer K. We need to generate a new string using the first K alphabets so that generated string can’t contain any repeated substring of length 2 or more and is lexicographically smallest. Sample ... Read More
In this problem, two players play a game by removing the string from their array, which is not already removed from the opponent's array. We need to decide the winner of the game. We can solve the problem using two different approaches. In the first approach, we can store the common strings with the set data structure. In the second approach, we can use a set to store already removed strings from both arrays. Problem statement – We have given two arrays called arr and brr. The size of the array is N and M, respectively. We need to decide ... Read More
In this problem, we have given a string suggesting the moving direction and starting coordinates. We need to find the revisited positions. We can use the set or map data structure to store the previously visited coordinates. We can say that position is revisited if we find any pair in the set or map. Problem statement – We have given a string str of length N containing the ‘L’, ‘R’, ‘U’, and ‘D’ characters. Also, we have given X and Y integers representing the starting position. We need to find the total number of coordinates revisited while following the path ... Read More
Images are a crucial part of web design in HTML since they improve the aesthetics and user experience of web sites. Managing an image's position is essential for attaining the intended layout and design effects. Setting an image's location in HTML is made simple with the help of this article. Along with examples from the real world and best practices, it will cover a variety of positioning strategies, such as inline, block-level, and absolute placement. Understanding Image Positioning in HTML The image element Overview of the element's function in HTML image embedding.Images can be embedded in HTML documents ... Read More
In this problem, we need to count the total occurrences of the substring X in the str when we find the substring Y in the given string. We can keep counting the occurrences of the substring X, and when we get the substring Y, we can print the count value. Problem statement – We have given a string str, X, and Y. The length of the strings is N, A, and B, respectively. We need to total the total number of substring X in the given string str before every occurrence of the substring Y. Sample examples Inputstr = "stuxystuxy"; ... Read More
C++ contains many precious features to enhance the performance of the code, and string_view class is one of them. It is introduced to create a lightweight and non-owning reference to a string. In this tutorial, we will discuss the string_view class and explore a few examples using the string_view class over the string class in C++. What is string_view? The string_view is a class in C++ that is used to create a read-only sequence of the string. It is a non-owning string type, meaning it does not manage the memory associated with the string and its reference. It acts as ... Read More
In this problem, we need to check whether we can get the valid balanced subsequence of the parenthesis by moving at most K characters of the string at the end. To solve the problem, we can use the stack data structure. The logic to solve the problem is that if we find more than K ‘)’ (closing parenthesis) before the ‘(‘ (opening parenthesis), we can’t make a string into a valid subsequence. Problem statement – We have given string str containing the ‘(‘ and ‘)’ sequence of parenthesis. The length of the string is N. Also, We have given a ... Read More
