My university syllabus for Theory of Computation / Automata Theory recommends the book:

Finite Automata and Formal Languages: A Simple Approach — A. M. Padma Reddy

Has anyone here used this book before or know where I could:

• access a legal PDF or ebook
• borrow it through a digital library
• find lecture notes or alternative books that cover the same topics

If not, I'd also appreciate recommendations for good alternative textbooks covering:

Module I: Introduction to Finite Automata

• Central Concepts of Automata Theory

• Deterministic Finite Automata (DFA)

• Nondeterministic Finite Automata (NFA)

• Applications of Finite Automata

• Finite Automata with ε-Transitions

Module II:

• Regular Expressions

• Regular Languages

• Properties

Module III:

• Properties of Regular Languages

• Context-Free Grammars

Module IV:

• Pushdown Automata

• Context-Free Languages

Module V:

• Turing Machines

• Undecidability

Any help or recommendations would be appreciated. Thanks! 🙏

Thanks in advance! 📚
