Symbols used in the expression:
[] : any one character in the enclosed string
+: one or more occurences
*: zero or more occurences
?: zero or one occurrence
q0 : start state
q4, q5 : final states
q0 -> q1 : string should
start with a/b/c
q1->q2 and q2 -> q2: there should one more more occurences of 1/2/3
q2->q3, q2->q4 & q3->q4: zero or more occurences of X, so either some X's followed by Y (q2->q3->q4) or directly 1/2/3 followed by Y (q2->q4)
q4->q5: M following Y, zero or one occurence of M, if zero occurence then q4 final state, if one M then q5 final state.

Using formulas for r_i, j^k find a regular expression for the following dfa: Determine a right-linear grammar G for the language accepted by the following dfa: Find the dfa that accepts the intersection of languages accepted by dfas from problem 1 and problem 3. Use the construction based on pairs of states.
Converting a DFA such as the one below to a regular expression requires 0/1 us to develop regular expressions for limited sets of paths --- those that take the automaton from one particular state to another particular state, without passing through some set of states. For the automaton below, determine the languages for the following limitations: 1.LAA = the set of path labels that go from A to A without passing through C or D. 2. LAB = the set...

In this assignment, you will implement a deterministic finite automata (DFA) using C++ programming language to extract all matching patterns (substrings) from a given input DNA sequence string. The alphabet for generating DNA sequences is {A, T, G, C}. Write a regular expression that represents all DNA strings that contains at least two ‘A’s. Note: assume empty string is not a valid string. Design a deterministic finite automaton to recognize the regular expression. Write a program which asks the user...
