5. In the process of transforming the following NFA to a regular expression, start- we first connect a new start state s to the start state of the given NFA and connect each final state of the given NFA to a new final state f as shown below. If we eliminate state O first, the modified NFA becomes of the following form. Fill out the three blanks in the following figure. (6 points) If we eliminate state 1 and state...

Regular Expressions
[25%] Identifier names in a hypothetical language may contain letters (A - Z and a - z), digits (0 - 9), and special symbols ($, _ , and #). Additionally, any acceptable identifier name must satisfy the following conditions: a) The first character of an identifier name must be a letter or special symbol. b) An identifier name may contain at most two special symbols. c) If an identifier name contains two special symbols, then all characters after...
6. Regular Expressions/SQL. Write SQL for the following problems on the university database. A. Find students whose name is properly capitalized (both first and last name start from an upper-case letter, rest of the name is lower-case). Hint: you can use [A-Z] to represent any upper case letter in regular expressions. B. Find course titles that consist of exactly 3 words (e.g., “Theory of Computation”). C. Find students whose SSN numbers has a pattern of 321 repeated twice (sequentially).
In this question, you will find a regular expression for the complement of the regular language ab*. a. First, draw a deterministic finite automation (DFA) for the language ab*. b. Now draw the DFA for the complement of ab*. c. Finally, convert your DFA to a regular expression. Show your work.
Provide a regular expression for the following languages: (a) the set of all strings over {a, b} that start with ab and end with ba, (b) the set of strings over {a, b} where four consecutive occurrences of both letters occur in every word.
Which of the following languages are regular. Prove (by providing a regular expression) or disprove. a. L1 = {ai bj ck dl | (i + j)mod 2 = (k + l)mod 2 , i, j, k, l ≥ 0} b. L2 = {ai bj ck dl | (i + j) = (k + l), i, j, k, l ≥ 0}
