In this lecture, we continue our discussion on Pumping Lemma for Regular Languages by solving Example 3 and proving that the given language is not regular.

🔹 What You’ll Learn:
✅ Recap of Pumping Lemma:
🔸 Understanding how the Pumping Lemma theorem is used to prove non-regularity.
✅ Step-by-Step Proof Using Pumping Lemma:
🔸 Example: Show that the given language is not regular.
🔸 Step 1: Assume the language L is regular.
🔸 Step 2: Choose a long enough string w from L.
🔸 Step 3: Apply the Pumping Lemma condition w = xyz.
🔸 Step 4: Show that pumping y leads to a contradiction, proving that L is not regular.
✅ Final Conclusion:
🔸 Understanding how Pumping Lemma is a useful tool for proving non-regularity.
🔸 Encouragement to watch previous lectures for more examples.

This video is essential for students studying Theory of Computation (TOC), Automata Theory, and Formal Languages.
