Student ID is 24241357 In this assignment, you will draw the automaton for a CanonicalLR(1), also called CLR(1), parser for a reference grammar. Youshould define the production rules and alphabet of terminals forthe grammar following the process described below. To learnhow to construct the automaton of a CLR(1) parser, readSections 4.7.1 to 4.7.3 of the reference textbook. Draw theautomaton exactly in the way shown in the reference textbook.Note that your submission must be a handwritten version, atyped submission will get a 0 out of 10.Grammar Construction Process (note that & means empty):A -> BACA -> DEB -> the last digit of your student IDC -> the second last digit of your student IDD -> the third last digit of your student IDE-> the fourth last digit of your student IDThen, if your student ID is odd then add the following rules:B-> εD-> εOtherwise, add the following rules:C -> εE-> εAn example: Suppose your student ID is 20130165. Then yourgrammar is as followsA -> BACA -> DEB -> 5C -> 6D -> 1E-> 0B-> εD -> εAlphabet of terminals is {5,6,1,0}

Step 1: A→B A CA \rightarrow B \ A \ CA→B A CA→D EA \rightarrow D \ EA→D EWe use the digits of the…

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
I need help Implementing a parser for the context-free grammar using Java Develop a parser that can take a sentence generated by the context-free grammar and parse it into a parse tree, which can be used to represent the structure of the sentence. In Java. Please follow the example
3. Given the following BNF grammar: -> d c | cd -> a la -> b | b Use the top-down recursive descent method which we discussed in the class to implement a parser (i.e. tdrd.parser.py) in python3 for the above BNF grammar. The input data file name is given from the command line. You may assume that there is a space character between two terminals (e.g. a a adc b ) in the data file.
Answer the given question with a proper explanation and step-by-step solution.
Write a BNF grammar describing the syntax of BNF; i.e., define the syntax of BNF itself using BNF. Use a pair of single quotes to use meta symbols like | and -> as terminal symbols, e.g., '|' and '->'. You may assume that non-terminals such as <identifier> and <special-symbol> are already defined.
Write a grammar for the language consisting of strings built only of theletters aand b. The strings may have any number of these letters, but the letter combinationsbabmust be in each stringsomewhere, and each stringmust startwithabb. For example, the strings bbababbbaa, bbbaaaababaa, and bbbabare in the language, whilea, aabb, baaa, and bbba are not.
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>
A variable name consists of only one letter. The non-terminal S is the start symbol. S = T V ; V = C , V | C T = float C = a-z We want to design an LR parser for this grammar. Create a complete parsing DFA, showing the closure for all states including the parsing marker in every rule, and transitions between the states. You can use the symbol @ as the parsing marker. States need to be numbered or named. You may write all required information in a table instead of drawing a DFA. There is no need to add $ at the end of start rule since there is a terminal at the end, i.e. the semicolon.
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 :)
exercise 1 is questions j, k and l
For the implementation of several compilers, it is important to understand which requirement compilers should satisfy. Explain three requirements that compilers should satisfy. Left-most, right-most and mixed derivations are often used to generate context-free grammars. A context-free grammar G has the production rules: S  aSS S b Generate the word aababbb using left most derivation.
