This comprehensive guide breaks down the core subjects covered in Puntambekar's text and explains why this material is foundational to modern computing. Core Pillars of Theoretical Computer Science

: Coverage of regular expressions, Arden’s Theorem, and the Pumping Lemma for regular languages.

Discussion on the limits of what can be computed (Undecidability and the Church-Turing Thesis) and the efficiency of those computations (NP-completeness, Time, and Space complexity). Publication Details Publisher: Technical Publications, Pune .

The text concludes with an introduction to computational complexity theory, defining how resource consumption (time and space) scales with input size:
