Question

“Follow of right most is follow of start symbol”

e.g

A->BC             //follow of C=follow of A

B->CaD          //follow of D =follow of B??

C->e/B

D->d

Comments

yes...

but if the production like X -> aYb, then follow(Y) can't include follow(X).

What is the reason behind this ?

let take

A ---> Bac

B --> gfC

C -->hi

So, follow(B) = a, Follow(C) = ?

C always place at ends of B ===> follow(B) should be follow(C).

i mean, if you replace B, in A ---> B a c, then it is like A ---> g f C a c,

So, your statement is right !
