2. Let M be the PDA defined by: Q = {90,91,92,93,94}, { = {a,b}, I = {a, $}, F = {q4} and transition function is defined as below: 8(90, , ) = (91, $) 8(91, a, a) = (91,a) 8(91,E, E) = (93.E) 8(91,6, a) = (92, ) 8(92, b, a) = (92, ) 8(92, , a) = (93, ) 8(93, E, a) = (93,8) 8(93, 5, $) = (94,5) draw the state diagram of the PDA. 2.2) [2 pts] Describe the language accepted by M
