我想A。与昨天一样{w | w begins ...,我找到了一个使用一些命令来设置的解决方案subsection title,但今天我找不到它,因为我不记得命令名称了。如果能提供参考链接,我将不胜感激。谢谢。

    \textbf{Solution}\\

    \phantomsection 
    \subsection*{a.}
    \addcontentsline{toc}{subsection}{\numberline{}a. What is the start state?}
    What is the start state?\\
        $M_1$ start states: $q_1$\\
        $M_2$ start states: $q_1$\\

    \phantomsection         
    \subsection*{b.}
    \addcontentsline{toc}{subsection}{\numberline{}b. What is the set of accept states?}
    What is the set of accept states?\\
        $M_1$ accepting states: $q_2$\\
        $M_2$ accepting states: $q_1, q_4$\\

    \phantomsection     
    \subsection*{c.}
    \addcontentsline{toc}{subsection}{\numberline{}c. What sequence of states does the machine go through on input $aabc$}
    What sequence of states does the machine go through on input $aabc$?\\
        $M_1$: $q_1 \rightarrow q_2 \rightarrow q_3 \rightarrow q_1 \rightarrow q_1$\\
        $M_2$: $q_1 \rightarrow q_1 \rightarrow q_1 \rightarrow q_2 \rightarrow q_4$\\

    \phantomsection 
    \subsection*{d.}
    \addcontentsline{toc}{subsection}{\numberline{}d. Does the machine accept the string $aabb$?}
    Does the machine accept the string $aabb$?\\
        $M_1$: No because the last state $q_1$ is not an accepting state.\\
        $M_2$: Yes because the last state $q_4$ is an accepting state.\\

    \phantomsection 
    \subsection*{e.}
    \addcontentsline{toc}{subsection}{\numberline{}e. Does the machine accept the string $\varepsilon$?}
    Does the machine accept the string $\varepsilon$?\\
    No, both of them do not accept string $\varepsilon$.
