It helps programmers understand the limits of computation—what can and cannot be solved by a computer (Decidability vs. Undecidability).
Puntambekar includes previous years' university questions at the end of each chapter. Solving these under exam conditions is the best way to build speed and accuracy.
The journey begins with the absolute fundamentals: alphabets (finite sets of symbols), strings (finite sequences of symbols), and formal languages (sets of strings). These building blocks are defined with precision and are used to formulate the concept of computation as a manipulation of strings according to specific rules. Let’s be pragmatic
