3. Using the grammar below, show a parse tree and a leftmost derivation for the statement. A = ( A + (B)) * C assign <idxpr expr>? <expr> <term> term <term factor factor (<expr>) l <term I <factor l <id> 4. Prove that the following grammar is ambiguous (Give sentence that has two parse trees, and show the parse trees):
) Using the following grammar, show a parse tree and a leftmost derivation for the following sentence (make sure you do not omit parentheses in your derivation): Grammar <assign> → <id> = <expr> <id> → A | B | C <expr> → <expr> + <term> | <term> <term> → <term> * <factor> | <factor> <factor> → (<expr>) | <id> Derive C = (A+B)*(C+A)*(C+B)

3. Consider the following grammar: expr term term tail term-tail-) add-op term term-ail 1 ε term → factor factor-tail factor. tain ε factor (expr) id literal add-op → +1 Draw a syntax tree for parsing each of cdf + (a25 + 84), (a25 + 84)*cdf, 84*cdf+ a25, a25+84 cdf a25*84*cdf. Note that a25 and cdf are identifiers and 84 is a literal You are not asked to do the tedious parsing process with stack snapshots. Instead you only need to...
