Let's consider a grammar for expressions is defined as follows.<assign> -> <id> = <expr><id> -> A | B | C | D<expr> -> <id> + <expr> | <id> * <expr> | ( <expr> ) | <id>1. Is this grammar unambiguous? Can you explain in detail?2. How can I design a PDA (PushDown Automata) M that recognizes the BNF (i.e. a metasyntax notation for CFG)?
Need help in Automata please, Using the rule of the above grammar, using leftmost derivation (or using a rightmost derivation) show step by step the partial derivation trees, yield for each of the sentential forms in deriving aababa
Please dont copy or use chegg answeres. Please! Also explain Let Σ = {a, b, c} and define the finite languages L1 = {, aa, ab, ca, bab, bba, ccc} L2 = {a, c, ca, ccc} L3 = {c, ba, bab, bba, abc}. 1. (L1 ∪ L3) \ (L1 ∩ L2) 2. (L2 ∩ L3)L1
I. Represent the Context – free grammar of the following language: L = (anbm I n>=0, m>n) II. Construct a derivation tree of the context – free grammars in Step I above to give the following sets of strings: A. aabbbb B. abb
Answer the given question with a proper explanation and step-by-step solution. Using the algorithm discussed in class, ”Big loop algorithm” show the transition diagram for a pushdown automaton (PDA) to recognize the language generated by G, which ahs the following grammer rules S →BAC A →a | b | c | ε B →bB | b C →cC | ε Fully define for the grammar G above, that is G = (....Describe in English what language the grammar G generates . Give an example showing that the grammar G above is ambiguous
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.
What language is generated by the following grammars? Is this anambiguous grammars, please justify your answer.
The grammar below generates Boolean expressions in prefix notation: B → O B B | not B | id O → and | or Give an attribute grammar over the above CFG to translate Boolean expressions into properly parenthesized Boolean expressions in infix notation without redundant parenthesis. For example, since operators and and or associate to the left, and and has higher precedence than or, expression and and a or b c d can be rewritten in infix notation as a and (b or c) and d.
Show that the following grammar is ambiguous: S → AB|aaaB, A → a|Aa,B → b. Construct an unambiguous grammar equivalent to the grammar in Exercise 8.
