A Regular Expression can be recursively defined as follows − ε is a Regular Expression indicates the language containing an empty string. (L (ε) = {ε}) φ is a Regular Expression denoting an empty language. (L (φ) = { }) x is a Regular Expression where L = {x} If X is a Regular Expression denoting the language L(X) and Y is a Regular Expression denoting the language L(Y), then X + Y is a Regular Expression corresponding to the language L(X) ∪ L(Y) where L(X+Y) = L(X) ∪ L(Y). X . Y is a Regular Expression corresponding to the language L(X) . L(Y) where L(X.Y) = L(X) . L(Y) R* is a Regular Expression corresponding to the language L(R*)where L(R*) = (L(R))* If we apply any of the rules several times from 1 to 5, they are Regular Expressions. ---------------------------------------------------------------------------------------------------------------- AUTOMATA THEORY || THEORY OF COMPUTATION https://www.youtube.com/watch?v=WQ8bJooiEeQ&list=PLLOxZwkBK52CTVrHjYa7-SpXlEtef1TqL COMPILER DESIGN https://www.youtube.com/watch?v=ZgrWX89iQZo&list=PLLOxZwkBK52AwK39Lh1Ny6xbwVPH7QDJg DATABASE MANAGEMENT SYSTEM https://www.youtube.com/playlist?list=PLLOxZwkBK52B6FqMOu6FfU4_5Id2cBStN DATA STRUCTURES https://www.youtube.com/watch?v=DFpWCl_49i0&list=PLLOxZwkBK52Akgqf4oSWPOQO9ROWS_9rc JAVA PROGRAMMING https://www.youtube.com/watch?v=ZFnRvpxpnOc&list=PLLOxZwkBK52BaOQCJrVvkc97uzeMsx9TT R PROGRAMMING https://studio.youtube.com/playlist/PLLOxZwkBK52C6_Nkmp0nFCreLfnfJgUL7/edit HTML TUTORIALS WITH IMPLEMENTATION || LEARN HTML IN 4 HOURS https://www.youtube.com/watch?v=a8W952NBZUE&t=1305s LEARN CSS IN 3 HOURS || CASCADING STYLE SHEETS FOR BEGINNERS https://www.youtube.com/watch?v=_-tR5OQS5cI&t=13s JAVA SCRIPT FOR BEGINNERS IN 7 HOURS || LEARN JAVA SCRIPT IN 7 HOURS || JAVA SCRIPT https://www.youtube.com/watch?v=BTuCzffKh8E&t=4s XML (eXtensible Markup Language) https://youtube.com/playlist?list=PLLOxZwkBK52A13WlDswibzX9od8_hfLhj OPERATING SYSTEM https://www.youtube.com/playlist?list=PLLOxZwkBK52C0LlaTlu5emckvUrlsG6QY ETHICAL HACKING https://www.youtube.com/watch?v=xOHKc9oxCdA&list=PLLOxZwkBK52ASKvoQSZxyj4NbdbLlpwaJ VI EDITOR BASICS IN LINUX / UNIX || LEARN VI EDITOR COMMANDS || LINUX || UNIX https://www.youtube.com/watch?v=pCxej5EPID8&t=38s HOW TO DOWNLOAD & INSTALL MySQL IN WINDOWS 10 https://www.youtube.com/watch?v=6dC0xjdIPZ0&t=302s PYTHON PROGRAMS https://www.youtube.com/playlist?list=PLLOxZwkBK52BC-U5nWzUm6dBsFIFRtQuO C PROGRAMMING https://www.youtube.com/watch?v=aUqO-dgzMw4&list=PLLOxZwkBK52AE9jFVOGZTJxaiAC_xB8Yy CORE JAVA TUTORIAL FOR BEGINNERS || LEARN CORE JAVA IN 15 HOURS || JAVA TUTORIALS FOR BEGINNERS https://www.youtube.com/watch?v=ZFnRvpxpnOc&t=4961s PYTHON TUTORIALS FOR BEGINNERS (తెలుగు లో) https://youtu.be/9hVzEKZQyMU PYTHON OOPS - MODULES - EXCEPTION HANDLING (తెలుగు లో) https://youtu.be/B-Rkxotn9Ok PYTHON NUMPY TUTORIAL IN TELUGU (తెలుగు లో) || COMPLETE NUMPY TUTORIALS IN TELUGU https://youtu.be/p2k_9I4VGYs PYTHON PANDAS TUTORIAL IN TELUGU (తెలుగు లో) || COMPLETE PANDAS TUTORIALS IN TELUGU || DATA SCIENCE https://www.youtube.com/watch?v=brgzTJwHIKI&t=4456s MATPLOTLIB LIBRARY - PYTHON PROGRAMMING (ENGLISH) https://www.youtube.com/playlist?list=PLLOxZwkBK52BQjsMFcnOB0wjzAUneSNfI PYTHON DATABASE CONNECTIVITY - MYSQL & MS-EXCEL https://www.youtube.com/playlist?list=PLLOxZwkBK52CIfeg1YISebeYu2Cfc_6Pl DATA STRUCTURES USING PYTHON (ENGLISH) https://www.youtube.com/playlist?list=PLLOxZwkBK52Apt7hZ--6D5q1QY6uQ6vgt ---------------------------------------------------------------------------------------------- Instagram : https://www.instagram.com/sundeepsaradhikanthety/
