Question

Draw a top down, push down automata for the following grammar.

S -> CaB

B -> baC | a

C -> Cb | a

engineering Computer-Science

Answer 1

Answer #1

The grammar contains left recursion for

C->Cb/a (A->A alpha/beta)

We can eliminate using

A->betaA'

A'->alphaA'/€

Please give positive rating as I took around 1and 1/2hour to solve correctly

Draw the state diagram of a Push-down Automata that recognizes the language A = {u#v_R | u, v {0, 1}* and u =v}. In this set, treat u and v as bit strings where v is the bit-complement of v. For example, 0100#1 101 A, 0100#1010 A #1010#1010 A and so on. Let M = (Q, sigma, , delta, q_0, F) be a push-down automata. Describe a push-down
