Consider the augmented grammar with {+, *, (, ), id} as the set of terminals.

S' $$\to$$ S

S $$\to$$ S + R | R

R $$\to$$ R * P | P

P $$\to$$ (S) | id

If I0 is the set of two LR(0) items {[S' $$\to$$ S.], [S $$\to$$ S. + R]}, then goto(closure(I0), +) contains exactly _________ items.

Consider the following grammar along with translation rules.

S $$\to$$ S1 # T {S.val = S1.val * T.val}

S $$\to$$ T {S.val = T.val}

T $$\to$$ T1 %R {T.val = T1.val $$ \div $$ R.val}

T $$\to$$ R {T.val = R.val}

R $$\to$$ id {R.val = id.val}

Here # and % are operators and id is a token that represents an integer and id.val represents the corresponding integer value. The set of non-terminals is {S, T, R, P} and a subscripted non-terminal indicates an instance of the non-terminal. Using this translation scheme, the computed value of S.val for root of the parse tree for the expression 20#10%5#8%2%2 is ___________.
