Q19

Consider the grammar given below: $S \rightarrow Aa$ $A \rightarrow BD$ $B \rightarrow b \mid \epsilon$ $D \rightarrow d \mid \epsilon$ Let $a,b,d$ and \ be indexed as follows:$$\begin{array}{|l|l|l|l|} \hline a & b & d & \ \\ \hline 3 & 2 & 1 & 0 \\ \hline \end{array}$$Compute the FOLLOW set of the non-terminal 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 $3210$)
