Master Regular Expressions with 12 Step-by-Step Examples 🧩 | Lecture 37

In this lecture, we solve 12 examples on Regular Expressions (RE) with step-by-step explanations, helping you understand how to construct REs for different language constraints. 🔹 What You’ll Learn: ✅ Basics of Regular Expressions (RE) – Understanding symbols and operations. ✅ Solved Examples on Regular Expressions: 🔸 RE for the set {010 + 111}. 🔸 RE for the set {ε, 0, 00, 000, …}. 🔸 RE for all strings starting with 0. 🔸 RE for all strings starting with 0 and ending with 1. 🔸 RE for strings containing an even number of 0’s. 🔸 RE for strings having at least two 0’s. 🔸 RE for strings having at most two 0’s. 🔸 RE for strings with any number of 0’s followed by more 1’s, then followed by any number of 0’s. 🔸 RE for strings where every 0 is preceded by 1. 🔸 RE for strings where an even number of 0’s is followed by an odd number of 1’s. 🔸 RE for strings ending with '00' or '11'. 🔸 RE for strings ending with 'b' or 'ba'.
