91.102 - Computing II Modularity, Information Hiding and Abstract Data Types.
Difficulty: Programs that solve “Real World” problems can get very large - up to millions of lines of code. Nobody can understand or remember that many lines of code.
Problem: How do we make it possible for normal human beings to contribute to such large endeavors?
Note: I did not say “How do we remove the difficulty”, because we do not KNOW how to really remove it. All we have is some techniques that help us get close enough to have - much of the time - usable programs within feasible budgets and time requirements.

* FCS Finite Automata Closure Properties of Regular Languages
Theorem. The class of regular languages is closed under union, intersection, subtraction, complementation, concatenation, Kleene closure and reversal.
Note: closure under union, concatenation and Kleene closure comes from the fact that regular languages are represented by regular expressions; closure under intersection, subtraction and complementation comes from from the fact that regular languages are represented by DFAs. The only part still missing is the closure under reversal. *
