INHERENT LIMITATIONS OF COMPUTER PROGAMS

CSci 4011. INHERENT LIMITATIONS OF COMPUTER PROGAMS. A PDA transition function takes as input a state, an input symbol, and:. QUIZ 2. a stack symbol. If P is a PDA then L(P) is the set:. { w | P accepts w }. Let G = (V,?,R,S) be a CFG then R is the set of:. Production rules.
