A,B,C,D are assumed to be states and showed an example by state transitions with stack diagram.
A is initial state and d is final state. As per requirement at least one 'a' is expected in language.
so inputting a is the first transition made.
In state B
1. If already stack contains a and input is a,insert a.
2.If input is b, then stack must contain a/b. In that case Insert b in to the stack
In state C
1.at least one b must be present as the minimum value f m is 1. So,If input element is b pop out it from the queue. It eliminates all bs
2.Popout all as from the queue until Zo is reached.
