Q51

Consider the following augmented grammar with $\{ \#, @, <, >, a, b, c \}$ as the set of terminals.

$$\begin{array}{l} S’ \rightarrow S \\ S \rightarrow S \# cS \\ S \rightarrow SS \\ S \rightarrow S @ \\ S \rightarrow < S > \\ S \rightarrow a \\ S \rightarrow b \\ S \rightarrow c \end{array}$$

Let $I_0 = \text{CLOSURE}(\{S’ \rightarrow \bullet S\})$. The number of items in the set $\text{GOTO(GOTO}(I_0<), <)$ is ___________
