Consider the following DFA [State Diagram Attached] - $$ \begin{array}{1} \text { DFA } M=(Q, Sigma, \delta, s, F) W Q=\{1,2,3\}, \Sigma=\{a, b\}, s=1, F=\{2,3\} \ \delta \mid a^{b} \ \begin{array}{1cc} 1 & 2 & 2 2 & 1 & 3 3 & \mid & 3 & 2 \end{array} \end{array} $$ Convert the given DFA to Regular Expression. ELIMINATE the states in the following ORDER State 2, State 3, then State $1 . $ CS.JG.008
