Draw a Turing Machine for the language generated by the grammar S --> aSa | bSb | c
Problem 1. Consider the grammar S → Y X Y X → a Y | Y Y → b b Y | X | ε where a and b are tokens. Remember that ε represents the empty string. Y → ε means that Y does not have to match any tokens. 1. Give a leftmost derivation for the string (sequence of tokens): bbabbabb 2. Give a rightmost derivation for the string (sequence of tokens): bbabbabb
The language generated by the grammar in Figure 7.8 uses the terminal x to introduce the base. Amore common convention is to separate the base from the string of digits by some terminal symbol. Instead of x 8 4 3 1 to represent , a language following the common convention would use 8 x 4 3 1. (a) Design an LALR(1) grammar for such a language and specify the semantic actions that compute the string’s numeric value. In your solution,...

2. The following context-free grammar (CFG) has A-productions. S + XY | XYZ X + YXYZ | a | A Y + XZ | ZY | 6 | A Z YZ | XY | X | C Using the algorithm in Chapter 13, find another CFG that generates the same language except for the empty word, and that does not have any A-productions.
15. Give a simple description of the language generated by the grammar with productions SaaA, A -> bS 16. What language does the grammar with these productions generate? A ->B B- Aa
Give an unambiguous grammar for the same language generated by the grammar: <fruit>* : -<yellow» | <red> <yellow» banana |mango | <empty> <red> ::- cherry | apple | <empty> "Same language" means that the unambiguous grammar can generate exactly the same set of strings as the ambiguous grammar. No more; no fewer. There will of course be a difference in how - by what NTSs and productions - at least some of those strings are generated * : -
The following context-free grammar (CFG) generates palindromes. This CFG has the following rules: S → ε, S → a, S → b, ..., S → z, S → aSa, S → bSb, ..., S → zSz. On an example of a palindrome cattac, show, step-by-step, how this palindrome will be generated by this grammar.
