Regular Expressions with Examples

In this video, we break down regular expressions (regex) step by step — from the basic building blocks to how they form regular languages. You’ll learn: 1- The three core operations: Concatenation, Union, and Kleene Star 2- The difference between the empty string (ε) and the empty set (∅) 3- The distinction between Kleene Star (★) and the plus (+) operator 4- How regex compares to arithmetic operations with simple analogies 5- Solved examples to help you actually use these operations By the end, you’ll understand how regular expressions are built, how they define regular languages, and why they’re such a powerful tool in computer science. If you’re a student, developer, or just curious about how search patterns and compilers work, this video is for you! #computerscience #programming #maths #tutorial #regex #regularexpressions #automatatheory #regextutorial #programmingbasics #coding #codinginterview #theoretical #codingforbeginners #cstheory #finiteautomata #engineering #education #algorithm #lecture #study #students #csstudentlife #university #universityeducation
