1.	A PDA machine configuration (p, w, y) can be correctly represented as:(a) (current state, unprocessed input, stack content)(b) (unprocessed input, stack content, current state)(c) (current state, stack content, unprocessed input)(d) none of the mentionedI had been asked this question in final exam.My question is taken from Deterministic PDA in division Push Down Automata of Automata Theory
Answer» Correct choice is (a) (CURRENT STATE, unprocessed input, STACK content) To ELABORATE: A machine CONFIGURATION is an element of K×Σ×Γ. (p,w,γ) = (current state, unprocessed input, stack content).
