GATE Computer Science (CS) 2019 Solved Papers

Consider the grammar given below:
S → Aa
A → BD
$\mathit{B}\to \mathit{b}\mid \mathit{E}$
$\mathit{D}\to \mathit{d}\mid \mathit{E}$
Let a, b, d, and $ be indexed as follows:

a	b	d	$
3	2	1	0

Compute the FOLLOW set of the nonterminal B and write the index values for the symbols in the FOLLOW set in the descending order. (For example, if the FOLLOW set is {a, b, d, $}, then the answer should be 3210)
