Construct a regular expression for the language accepted by the following DFA, defined as (Q,,,q0,F) where - Q={q1,q2,q3} - ={a,b} - q1 is the start state - F={q1,q3} - is given by 1. Provide a state diagram for this DFA 2. Following the algorithm seen in class, create a GNFA from this DFA. This involves creating new start and final states and transitions. 3. Then the algorithm removes the internal states one by one in arbitrary order. Since removing the states in a different leads to a different solution, to ease grading, please continue as follows: (a) Remove state q2 and show the result. (b) Remove state q1 and show the result. (c) Remove state q3 and show the result
