In Example 6.1, show a derivation tree for the string ababbac, using both the original and the modified grammar. EXAMPLE 6.1 Consider G = ({A, B}, {a, b, c}, A, P) with productions A→a|aaA|abBc,B→abbA|b.A→a|aaA|abBc,B→abbA|b. Using the suggested substitution for the variable B, we get the grammar Ĝ with productions A→a|aaA|ababbAc|abbc,B→abbA|b.A→a|aaA|ababbAc|abbc,B→abbA|b. The new grammar Ĝ is equivalent to G. The string aaabbc has the derivation A ⇒ aaA ⇒ aaabBc ⇒ aaabbc in G, and the corresponding derivation A ⇒ aaA ⇒ aaabbc in Ĝ. Notice that, in this case, the variable B and its associated productions are still in the grammar even though they can no longer play a part in any derivation. We will next show how such unnecessary productions can be removed from a grammar.
Write a BNF grammar for simple phone numbers e.g. (9)123-4567 (21)987-1234 The number must start with a left parenthesis, followed by 1or 2 digits, followed by a right parenthesis, followed by 3 digits, followed by a hyphen, followed by 4 digits. All digits, including 0, can be used anywhere a digit is required. There must be at least 3 rules in your grammar. The goal non-terminal should be called <phone>.
(20 Points) Consider the following grammars where S is the start symbol and a, b, and c are terminal symbols and A, B, and C are non-terminal symbols.S ---> aA | bB | cCA --> aA | aB | aB --> bB | bC | bC --> cC | cExplain in your own words what the grammar generates. Which of the following sentences are in the language generated by the grammar? Show derivations. If a sentence cannot be generated by the grammar, explain why abcabcab aaaaaabb cccccaaaa bbbbbbbc aaaaaaccc
QUESTION 4 : Consider G be a Context Free Grammar for which the production Rules are given below:S -> aB|bAA -> a|aS|bAAB -> b|bS|aBBDrive the string aaabbabbba using the above grammar by using Left Most Derivation.
Please create a CKY table for each of the remaining sentences. Given grammar is: S -> NP VP NP -> 'I' | 'Texas' | 'South Padre' | 'hotel' | 'beach' | 'view' | 'sunrise' | 'vacation' | 'boat' | 'water' | 'trip' | 'waves' | 'speed' VP -> 'want' 'to' V | 'like' NP | 'Go' 'to' NP | 'Get' 'a' NP | 'On' 'the' NP | 'Love' 'the' NP | 'Book' 'a' NP | 'Need' 'this' NP | 'Prefer' 'the' NP | 'enjoy' NP V -> 'travel' | 'swim' | 'be' Waves are high Prefer the boat I enjoy speed
refer to the grammar S -> aSa | aXa X ->aXa | bYb Y -> bYb | empty where S is the start symbol, non-terminals = {S, X, Y}, terminals = {a, b} This Question: Use the pumping lemma to show that the language generated by this grammar is not regular.
Consider the ambiguous grammar S → ABS | ABA → aA | λB → bB | λ What is the shortest string in L(S) other than λ that can be used to show the grammar is ambiguous? Write the string without any spaces or quotation marks. Now show the grammar ambiguous by giving two derivations for the string (each derivation should have a particular important property). Give the two shortest derivations you can find, writing the shorter one in the first box. Your derivations should begin with S, end with your chosen string, and only make one substitution per step. Do not include any spaces, quotes, or lambdas in your answer. Use the ">" character to represent the right arrow. For example, S>aSb>ab might be a legal derivation for a string in another language.
Consider the following grammar: X -> (Y) | b Y -> Y, X | X for the input string ((b),b,(b,b)),show the parsing stack and actions of the parsing SLR(1) parser. Is this grammar an LR(0) grammar? If not, describe the LR(0) conflict. If so, construct the LR(0) parsing table, and describe how a parse might differ from an SLR(1) parse.
Alert dont submit AI generated answer. please explain in details. The alphabet is E = {a, b, c, d} Is the below language B context-free or non-context free? If B is context-free, give a context-free grammar that generates B. If B is non-context free, using the pumping lemma prove that B is not context-free. B = {a2i+1b2k+2c3k+1d3i+2| i >= 1, k >= 1}
