🎓 Welcome to CS Pathshala!

📘 Lecture 96 – Unit 5 (TAFL)
Post’s Correspondence Problem (PCP)

In this lecture, we study Post’s Correspondence Problem (PCP), one of the most important undecidable problems in Theory of Computation. PCP helps us understand the concept of undecidability and plays a major role in proving that certain problems cannot be solved by any algorithm.

🔹 In this lecture, we cover:
✅ What is Post’s Correspondence Problem (PCP)
✅ Structure of domino pairs in PCP
✅ How matching of strings works
✅ Solution and non-solution cases
✅ Why PCP is undecidable
✅ Importance of PCP in proving undecidable problems

📌 This topic is very important for AKTU exams, GATE, and NET, especially for proof-based and conceptual questions in Automata Theory.

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