This is a question from my first Theory of Computing practice homework assignment included as an image. I need help with all three parts (a,b, and c) if possible.
See the image. a.Construct a context-free grammar generating C.Explain how your construction accounts for each rule. b.We could eliminate one rule from Cand make it regular. Which rule would that be, and why would it work? You do not need a formal proof, but you do need an explanation.
Consider the following context-free grammar defined by the tuple G and by the rules that appear in the image. a) Show that no string in L (G) contains "ba" as a substring. It is suggested to proceed by induction over the length of the chain. b) Informally describe L (G). Justify your answer using a). (Remember that the symbol | is disjunctive, and is used in this case to compactly represent four rules.)
Question (q)
This question is about context-free grammars and parsing, and Turing machines (TM’s). Question 1) Consider the following context-free grammar G over the alphabet Σ = {a, b, c}: S → aSb | ε | acSba | abc Using any of the grammar transformation techniques we saw in this module, construct a CNFgrammar that generates the same language as the grammar G of Question 1.Make sure you include in your answer all individual steps that you followed. Please help me with this question :)
1. Use the algorithm described in class that takes a CFG and converts it into a CNF (Chomsky Normal Form) grammar that generates the same language as the original grammar, except possibly for the string A, to answer the following question. As part of your answer, you should say which variables are nullable, and you should give the appropriate grammar after each step of the algorithm. There are four steps. Give a CFG (context-free grammar) in CNF (Chomsky Normal Form) that generates the same language, except possibly for the string A, as the following grammar: SAB AB →bAa A → aaB bb
Answer only a)( and b) parts . Rest all parts already being Answered. Thank you
Hello I. Need help in theoretical computer science Subtask (a) Let G be a context-free grammar with the start variable S and the following rules, which describes a language using the alphabet Σ = {0, 1}. Show that almost all words in the language described by this grammar are 4-inflatable.
4. Explain ambiguity. Do left factoring with the following grammar- Salablabclabcd
The following is a grammar for regular expressions over symbols a and b only, using + in place of 1 for union, to avoid conflict with the use of vertical bar as a metasymbol in grammars: a) Left factor this grammar. b) Does left factoring make the grammar suitable for top-down parsing? c) In addition to left factoring, eliminate left recursion from the original grammar. d) Is the resulting grammar suitable for top-down parsing?
ANNSWER BY TRUE OF FULSE: (No need to explain as I already know the answer but I want to check my answers. i. For every regular language, G, there exists a push down automata, M such that L(G)=L(M). ii.The following grammar represents the language of all strings over the alphabet a and b, with the total number of a’s being equal to the number of b’sS → aSb | aabb iii. The following languages MUST at least be defined by Pushdown Automata L = {ab, abab, ababab, abababab, ...}. iv. The correct CFG for the language L = (aa + bb)* isS → aB | bA | λ;A → aS;B → bS.
