39.. (a) Implements both <EOS Visual Studio .NET PDF 417 > and <SOS>. (b) Uses neither <EOS> nor <SOS>.

Using the standard encoding conventions, draw a circuit diagram that will implement the machine given in Example 1.10, as follows: (a) Implements both <EOS> and <SOS>. (b) Uses neither <EOS> nor <SOS>.

Using the standard encoding conventions, draw a circuit diagram that will implement the machine given in Example 1.14 (include <EOS> but not <SOS> in the input alphabet). Using the standard encoding conventions, draw a circuit diagram that will implement the machine given in Example 1.

16; include the <SOS> and <EOS> symbols. Let I = {a, b, e}. Let L = {x E {a, b, e}* I Ix Ib = 2}.

(a) Draw a DFA that accepts L. (b) Formally specify the five parts of a DFA that accepts L..

1.40. Draw a DFA accepting {x E {a, b, e}* Ievery b in x is eventually followed bye}; that is, x might look like baabaeaa, or beaee, and so on.

1.41. Let I = {a, b}.

Consider the language consisting of all words that have neither consecutive as nor consecutive bs. (a) Draw a DFA that accepts this language. (b) Formally specify the five parts of a DFA that accepts L.

1.42. Let I = {a, b, e}.

Let L = {x E {a, b, e}* Ilx I.;; 0 mod 3}. (a) Draw a DFA that accepts L.

(b) Formally specify the five parts of a DFA that accepts L. 1.43.

Let I = {a, b, (, *, )}. Recall that a Pascal comment is essentially of the form: (* followed by most combinations of letters followed by the first occurrence of *). While the appropriate alphabet for Pascal is the ASCII character set, for simplicity we will let I = {a, b, (, *, )}.

Note that (*b(*b(a)b*) is a single valid comment, since all characters prior to the first *) (including the second (* ) are considered part of the comment. Consequently, comments cannot be nested. (a) Draw a DFA that recognizes all strings that contain exactly one valid Pascal comment (and no illegal portions of comments, as in aa(*b*)b(*a).

(b) Draw a DFA that recognizes all strings that contain zero or more valid (that is, un nested) Pascal comments. For example, a(*b(*bb*)ba*)aa and a(*b are not valid, while aOa(**)b(*ab*) is valid. 1.

44. (a) Is the set of all postfix expressions over {A, B, + , -, *, I} with two or fewer operators a FAD language If it is, draw a machine. (b) Is the set of all postfix expressions over {A, B, +, -, *, I} with four or fewer operators a FAD language If it is, draw a machine.

(e) Is the set of all postfix expressions over {A, B, +, -, *, I} with eight or fewer operators a FAD language If it is, draw a machine. (d) Do you think the set of all postfix expressions over {A, B, +, -, *, I} is a FAD language Why or why not 1.45.

Let I = {a, b, e}. Consider the language consisting of all words that begin and end with different letters. (a) Draw a DFA that accepts this language.

(b) Formally specify the five parts of a DFA that accepts this language.. Introduction and Basic Definitions Chap. 1 1.46. Let I = {a, b, c}.

(a visual .net PDF 417 ) Draw a DFA that rejects all words for which the last two letters match. (b) Formally specify the five parts of the DFA.

1.47. Let I = {a, b, c}.

(a) Draw a DFA that rejects all words for which the first two letters match. (b) Formally specify the five parts of the DFA. 1.

48. Prove that the empty word is unique; that is, using the definition of equality of strings, show that if x and yare empty words then x = y. 1.

49. For any two strings x and y, show that Ixy 1= Ixl + Iy I. 1.

50. (a) Draw the DFA corresponding to C = <{a, b, c}, {to, h}, qo, 8, {h}>, where 8(to, a) = to 8(tt, a) = to 8(to, b) = h 8(t!, b) = t1 8(to, c) = t1 8(h, c) = to (b) Describe L(C). (c) Using the standard encoding conventions, draw a circuit diagram for this machine (include <EOS> but not <SOS> in the input alphabet).

1.51. Let I = {I, V, X, L, C, D, M}.

Recall that VVI is not considered to be a Roman numeral. (a) Draw a DFA that recognizes strict-order Roman numerals; that is, 9 must be represented by VIllI rather than IX, and so on. (b) Draw a DFA that recognizes the set of all Roman numerals; that is, 9 can be represented by IX, 40 by XL, and so on.

(c) Write a Pascal program based on your answer to part (b) that recognizes the set of all Roman numerals. 1.52.

Describe the setof words accepted by the DFA in Figure 1.9. 1.

53. Let I = {O, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Let Ln = {x E I *1 the sum of the digits of x is evenly divisible by n}.

Thus, L7 = {A, 0, 7, 00, 07,16,25,34,43,52,59,61,68,70,77,86,95,000,007, ...

}. (a) Draw a machine that will accept L7 (b) Formally specify the five parts of the DFA given in part (a). (c) Draw a machine that will accept L3 .

(d) Formally specify the five parts of the DFA given in part (c): (e) Formally specify the five parts of a DFA that will recognize Ln. 1.54.

Consider the last row of Table 1.3. Unlike the preceding three rows, the outputs in this row are not marked with the don"t-care symbol.
