📘 Lecture 48 – Unit 3 (TAFL)
Context Free Grammars (CFG) – Ambiguity

In this lecture, we study the concept of Ambiguity in Context Free Grammars (CFG), which occurs when a single string can have more than one derivation or parse tree. This is an important topic for understanding the limitations of grammars.

🔹 In this lecture, we cover:
✅ Introduction to Ambiguity in CFG
✅ Definition of Ambiguous Grammar
✅ Multiple derivations (LMD & RMD) for the same string
✅ Multiple parse trees for a single string
✅ Examples of ambiguous grammars

📌 This topic is very important for AKTU exams, GATE, and NET, especially for theory and problem-based questions in Formal Languages.

📚 Language: Easy Hindi + English (Concept + Examples)
🎯 Helpful for B.Tech CSE students, semester exams, and competitive exam preparation
