Question 1

What is Regular Expression?

Accepted Answer

Regular Expression (regex) is a powerful tool used in computer programming and data processing to search, match, and manipulate text patterns. It is a sequence of characters that defines a search pattern, allowing you to perform complex search and replace operations. Regular expressions are widely used in tasks such as text parsing, input validation, data extraction, and pattern recognition. They provide a concise and flexible way to specify patterns that are to be matched against a given input string. Learning Regular Expressions can greatly enhance your programming and data manipulation skills, making it an essential skill for various fields such as web development, data analysis, and software engineering.
