How to Find FIRST & FOLLOW in Grammar | Compiler Design | Parsing Techniques
In this video, we explore FIRST and FOLLOW Sets in Grammar, which are essential for Top-Down and Bottom-Up Parsers in Compiler Design. Understanding FIRST and FOLLOW helps in constructing LL(1) Parsing Tables, SLR(1), LR(1), and LALR(1) Parsers.
🔹 What You’ll Learn:
✅ Introduction to FIRST & FOLLOW Sets
🔸 Why are FIRST & FOLLOW sets necessary in Syntax Analysis?
🔸 How do they help in Predictive Parsing & LR Parsing?
✅ Step-by-Step Calculation of FIRST Set
🔸 Rules for computing FIRST sets.
🔸 Handling epsilon (ε) in FIRST set.
✅ Step-by-Step Calculation of FOLLOW Set
🔸 Rules for computing FOLLOW sets.
🔸 Handling cases with multiple derivations.
✅ Example Walkthrough:
🔸 Given a Context-Free Grammar (CFG), we will compute FIRST & FOLLOW step by step.
🔸 Demonstrating how to apply these sets to Parsing Table Construction.
✅ Applications of FIRST & FOLLOW in Parsing
🔸 LL(1) Parsing Table Construction.
🔸 SLR(1), CLR(1), and LALR(1) Parsing Table Construction.
✅ Final Conclusion:
🔸 Why FIRST & FOLLOW sets are the foundation of Parser Construction?
🔸 Encouragement to watch upcoming videos on LL(1), LR Parsing & Predictive Parsing Table Generation.
📌 This video is perfect for students learning Compiler Design, Predictive Parsing, and Grammar Analysis Techniques.
