- Consider the following Grammar:A-> ABd|Aa|aB-> Be|bRemove left recursion.Q1: Define the below terms with examples: Lexemes, Token, Reserved Words, Metalanguage, Context-Free Grammar, Derivation, and Production Rule. Q2: Explain the advantages of EBNF over BNF grammar; use examples as needed. Take an example BNF grammar of your choice and transform the BNF grammar to the EBNF format.1. Use the algorithm described in our course materials (videos) that takes a CFG and converts it into a CNF 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: S АВ → abA|A → bBb|bb A B
- A) Write a BNF grammar for the language consisting of strings built only of the letters a and b. The strings may have any number of these letters, but the letter combinations bb must be in each string somewhere, and each string must start with a aa. For example, the strings aaabbabbba, aaaababba, and aababbabb are in the language, while a, bba, ababb, aabaa, and bbaa are not. B) Draw the parse tree for string aabbaaba according to the previous grammar: C) Describe, in complete English sentences and “layman’s terms,” the language defined by the following grammar in BNF (start symbol is <S>):<S> ::= <A>a | <B>b<C> ::= c<A> ::= a<A>a | <C><B> ::= b<B>b | <C>Topic: Parsing Problem 2. Consider the following context-free grammar What is the language L described by the grammar? Compute the first sets for S, X, and Y. You must show the iterations of the algorithm separately Compute the follow sets for S, X, and Y. You must show the iterations of the algorithm separately Construct the LL(1) parsing table for the grammar. It is enough to just show the table Show the steps in parsing the strings from LWhat is a shift reduce parser? Explain in detail the conflicts that may occur during shift reduce parsing. Check whether the following grammar is a LL( 1 ) grammar S->iEts | iEtSes I a E->b also define the FIRST and FOLLOW procedures.
- 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. abbGiven the language above, create a context free grammar for LThe correct statements are: S→ € is allowed in a context free grammar. SaSa is allowed in a context free grammar. Sa → T is allowed in a context free grammar. OT→ TT is allowed in a context free grammar.
