Consider the Turing machine M={{qo, 91, 92, 93, 94}, {a, b}, {a, b, x, y, B}, 5, 90, B, {q4}) where d is defined as follows: 8 (qo, a)=(qi, x, R) (q, a)=( 91, a, R) 8 (91, y)=(q, y, R) 8 (q, b)=( 92, Y, L) 8 (92, Y)=( 92, y, L) 8 (92, a)=( 92, a, L) 8 (92, X)=( 90, X, R) 8 (90, Y)=( 93, Y, R) (93, Y)=( 93, Y, R) 5 (q3, B)=( 94, B, R) Assume the head of the machine initially points to the left-most letter. a) Give the instantaneous descriptions for the input "aabb". Is "aabb" accepted by the machine? b) Give the instantaneous descriptions for the input. Is "abbb" accepted by the machine? c) What is the language accepted by M
