Question
7. The following shows the state transition diagram of a Turing machine for language A = {a² In>0}.
For example, strings a, aa, aaaa, and aaaaaaaa are members of language A. Modify this Turing machine to
recognize language B = {a(2)-1 | n ≥ 0). For example, strings e, a, aaa, and aaaaaaa are members of
language B. You can modify, add, or remove transitions, but you cannot add or remove any states.
