Consider the following regular grammar with start symbol S and terminals {x, y}. S → xS S → yX S → yY X → xX X → yS Y → xY Y → λ List four strings, each of length less than 4, accepted by this grammar. (Include ε if it is accepted.) List four strings, each of length less than 4, not accepted by this grammar. (Include ε if it is not accepted.) In English, describe the language represented...
Give a set notation definition of the language generated by the grammar S → aS | aA | a A → aAb | ab
indicate what language is generated by the context-free grammar. The alphabet is Σ = {a, b} • S → SaS | bS

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
Draw a Turing Machine for the language generated by the grammar S --> aSa | bSb | c
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.
