I am confused in following kinds of Grammar they are;-

1) S - > AB

A -> Ba

B -> Bb

B - > c

2) S - > AB

A -> Ba

B -> Bb

B - > Epsilon

3) S - > AB

A -> Ba

B -> Bb

B - > dollar

what will be the I0 state of these three grammars.

In 1st what will be the look ahead of B -> Bb and B - > c are we need to consider a or a/b.

In 2n what will be the look ahead of B -> Bb and B - > c are we need to consider a or a/epsilon.

In 3rd what will be the look ahead of B -> Bb and B - > c can we consider $as look ahead symbol. | 708 views ## 2 Answers 0 votes The last Case is not required for understanding and you should not write$ in the production. It represents the start of the stack.

For Concept:

@Shubhanshu In short, look-ahead of a non-terminal is the same for its every production.
