Question: Question 3 . Prove that a language A is Turing - recognizable if and only if A ? m * A T M - Structuring

Question 3. Prove that a language A is Turing-recognizable if and only if A?m*ATM-
Structuring your proof: Proving the two implications separately is a good strategy.
)>( Assume A is recognizable (i.e., there's a TM whose language is A), and provide a mapping reduction.
(lArr) Assume A?mATM(i.e., there's a computable f with winA iff f(w)inATM), and provide a TM for A to show A is recognizable.
