Description: 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 begin with ‘A’ and end with ‘T’. Note: assume empty string is not a valid string. Design a deterministic finite automaton to recognize the regular expression. Write a program which...
