Is $ a terminal or not ?

Question

Follow(S) comes as {(, ). $ }

So, do we count $ as terminal or not.

Could anyone please tell me, $ should be considered as terminal or not ?

** Although I think, I should not count it as a terminal because we do not put $ in the terminal set of CFG.

See here : https://en.wikipedia.org/wiki/Context-free_grammar#Example

$ is also marker to identify that parsing of string has been successfully completed. 

Answer 1

Follow of  S is  {(, ). $ }

Because S is a start Symbol and follow of start symbol is always $ .

So no of terminals here are 3.

Answer 2

follow of S will be{ ), $ }

number of terminal=2;

hence $included as terminal

Comments

follow of S is  {(, ). $ } &  it is correct.

please give me a reference why you r considering $ as terminal ?

ohhh i was mistaken...i left '(' in the follow .But again when i tried i found that this grammar is ambiguous ..so LL(1) not possible.

also we can take $ in the terminal list...
