follow(A)={a,b}
follow(B)=follow(S)=follow(A)={a,b}
follow(A) is pretty straight forward
follow(B) is this because since it can be seen that it is equal to
follow(S), as follow B in the grammar does not have anything so hence it is
equal to the production that resulted it and hence follow(S) and so on
similarly it is equal to follow(A).
