1. (a) Consider the following grammar: E + E+TE-TT T + T F T/FF F (E) | id Why is this grammar not LL? Give a rightmost derivation and parse tree for the following expression: 7-8* (3 + 2) / 4 + 11 Note that all the numbers are ids, as in class, and I'm asking for BOTH the derivation and the parse tree (which are not always identical). (b) Now consider an equivalent LL grammar: E T T' F + TE + +TE' -TE' + FT' *FT' /FT' E + (E) id Give a leftmost derivation and parse tree for the same expression: 7-8 * (3 + 2) / 4 + 11 Again, note that all the numbers are ids, as in class, and I'm asking for BOTH the derivation and the parse tree (which are not always identical)
