4. Detailed Notes Content: 11 distinct module files covering:
   • Introduction: Compilers vs Interpreters, Compiler types.
   • Phases of a Compiler: Structural trace of result = a + b * 2;.
   • Writing Tools: Lex/Flex, Yacc/Bison, ANTLR, LLVM.
   • Lexical Analysis: Patterns, lexemes, tokens, and buffer pairs.
   • Bootstrapping: Tombstone (T) Diagrams, cross compilers, Canadian Cross.
   • Finite Automata: Thompson's Construction, NFA-to-DFA Subset Construction, DFA Minimization (Myhill-Nerode), and a step-by-step solved problem.
