Consider the following grammar (G1) for simple assignment statements. (The symbols in double quotation marks are terminal symbols.) assign → id “ = ” expr id → “A” | “B” | “C” expr → expr “ + ” expr | expr “ ∗ ” expr | “(” expr “)” | id a) Give a (leftmost) derivation for string A = B ∗ A + C. b) Give the parse tree for string A = B ∗ A + C. c)...

1.) Consider the following grammar in which S, A, and B are nonterminal symbols and S is the start symbol. S → 1A | 0B A → A0 | 1B B → 10A| 1 Show that the grammar is ambiguous by showing two parse trees for the sentence 1110110 using leftmost derivation.
Consider the following grammar (S, A, B, and C are nonterminal symbols; S is the start symbol; 0 and 1 are terminal symbols): S → AA A → BCB B → B0 | B1 | 0 | 1 C → 00 | 11 Which of the following sentences are in the language generated by the grammar? Show derivations for the sentences that can be generated. If a sentence cannot be generated by the grammar, explain why. a) 10010001 b) 01101101...

Consider following note that are terminals. E rightarrow e + t | t t rightarrow ID | j x rightarrow e, E | E Eliminate left Then perform left factoring for the grammar Compute the first set for all symbols in the grammar Compute the follow set for non-terminal in the grammar. Can you please explain how to get first follow set? Thanks.
The questions in this section are based on the grammar given as the following: prog -> assign | expr assign -> id = expr expr -> expr + term | expr - term | term term -> factor | factor * term factor -> ( expr ) | id | num id -> A | B | C num -> 0 | 1 | 2 | 3 (2a) What is the associativity of the * operator? (5 points) (2b) What...
