Every concept is accompanied by multiple solved problems, graduating from simple string matching to complex language design.
As languages become more complex—requiring balanced structures like parentheses or nested blocks—finite automata fail due to a lack of infinite memory. This introduces Context-Free Grammars. finite automata and formal languages by padma reddy pdf
