Finite Automata and Formal Languages (A Simple Approach) by A.M. Padma Reddy is a highly regarded textbook in computer science, specifically tailored for undergraduate students at universities such as VTU, JNTU, and Bangalore University. The book simplifies the complex Theory of Computation by using a problem-solving approach and providing over 250 worked examples. Overview of Finite Automata and Formal Languages
The text explores the relationship between abstract computing devices (automata) and the languages they can recognize (formal languages).
Finite Automata (FA): These are mathematical models of machines that read input strings and either accept or reject them based on a finite set of states.
Formal Languages: These consist of sets of strings formed from a finite alphabet according to specific rules, such as regular expressions or grammars. Core Concepts Covered
Padma Reddy’s book systematically breaks down the following modules: Automata Theory and Formal Languages

This subject is fundamental in understanding the theoretical foundations of computer science, including the study of algorithms, computability, and complexity. Which would you prefer
Finite automata are simple machines that can be in one of a finite number of states. They are used to recognize patterns in strings of symbols, forming the basis for lexical analysis in compilers and for the specification and verification of system behavior. Formal languages, on the other hand, are sets of strings of symbols that are defined by a set of rules, known as a grammar or by a finite automaton.
