a)Construct a deterministic push down automaton that accepts thefollowing language: {0n 1m/ n ≤ m }. b)Find a context-free grammar that generates the languageaccepted by the PDA P = ({q0,q1},{a,b},{A, Z0}, ∆, q0,Z0,{q1} with thetransitions: δ (q0, a, Z0) = {( q0, AZ0)} δ (q0, b, A) = {( q0, AA)} δ (q0, a, A) = {( q1 , λ )} c) Is the following grammar ambiguous? Why? S → aSbS | SbaS | λ Attached
