To form the possessive of plural nouns that end in s, a. add --s'. b. add just the apostrophe after the s. c. add --'s d. add --es'.

We want to construct a regular expression for the language accepted by the following DFA: b а,b a ´a 92 Follow the general algorithm as seen in class and in our textbook to construct this regular expression. (In order to simplify grading, you don't need to simplify the regular expressions, and you should follow the state removal in the specified order.) 1. Construct a GNFA (in the special form described in the textbook and in class) equivalent to this DFA. 2. Remove the state q1 from this GNFA. 3. Remove the state q2 from this GNFA. 4. Remove the state qo from this GNFA.

Assume the following rules of associativity and precedence for expressions: Precedence Highest *, /, not +, -, &, mod - (unary) =, /=, =, > and Lowest or, xor Left to right Associativity Show the order of evaluation of the following expressions by parenthe- sizing all subexpressions and placing a superscript on the right parenthe- sis to indicate order. For example, for the expression а +b* с + d the order of evaluation would be represented as ( (a + (b * c)')² + d)³ а. а * b 1 + C b. a (b - 1) / c mod d с. (а b) / с & (а * е / а - 3) d. -a or c = d and e е. а > b хоr c or d <3 17 f. -a + b
