Theory of Computation Problem 3: Let G be an arbitrary CFG (Context-free Grammer), and let DG be the string-pushing PDA(pushdown automata) for it. Let w be some string of length n in L(G). Suppose you know that the leftmost derivation of w in G consists of m substitutions. How many transitions would be in the corresponding computation of DG for input string w? Justify your answer carefully! All information is given ----------------------------------------------------------------- Upvote for the right answer!! Thanks
