In this article, we are given a string containing some non-ASCII characters and the task is to remove all non-ASCII characters from the given string....

The purpose of this article is to get the ASCII code of any character by using JavaScript charCodeAt() method. This method is used to return the number indicating the Unicode value of the character at the specified index....

In HTML forms, we often required validation of different types. Validate existing email, validate password length, validate confirm password, validate to allow only integer inputs, these are some examples of validation. In a certain input field, only Ascii characters are allowed i.e. there is not allowed any Non-ASCII characters (Ex: ñ). We can also validate these input fields to accept only ASCII characters using express-validator middleware....

MongoDB, the most popular NoSQL database, is an open-source document-oriented database. The term ‘NoSQL’ means ‘non-relational’. It means that MongoDB isn’t based on the table-like relational database structure but provides an altogether different mechanism for storage and retrieval of data. This format of storage is called BSON ( similar to JSON format)....

Given a String the task is to convert the given string into ASCII code using PHP. ASCII is the American Standard Code for Information Interchange, which is a widely used standard for encoding characters in computers and digital communication systems....

Given an integer X and two strings S1 and S2, the task is to check that string S1 can be converted to the string S2 by shifting characters circular clockwise atmost X times....

Given string str of length N, the task is to check if the given string contains only special characters or not. If the string contains only special characters, then print “Yes”. Otherwise, print “No”....

In Python3, ascii_letters is a pre-initialized string used as string constant. ascii_letters is basically concatenation of ascii_lowercase and ascii_uppercase string constants. Also, the value generated is not locale-dependent, hence, doesn’t change....

Given two strings str1 and str2, the task is to check if the two given strings are isomorphic to each other or not....

Given an input string S, the task is to make it a palindrome and calculate the minimum cost for making it a palindrome, where you are allowed to use any one of the following operations any number of times:...

Given a string, the task is to count the number of alphabets having ASCII values less than and greater than or equal to a given integer k....

Given a string ‘str’, two integers ‘k’ and ‘p’. The task is to count all the sub-strings of ‘str’ having exactly ‘k’ characters that have ASCII values greater than ‘p’....
