\item Create Regular Expressions for the following languages:
    \begin{enumerate}
        \item The set of binary strings which are divisible by 4 when interpreted as an integer value.
        \begin{itemize}
            \item Assuming right-to-left: 00(0+1)$^{*}$
        \end{itemize}
        \item The set of binary strings with an odd number of $1$s.
        \begin{itemize}
            \item 0$^{*}$1(0+101+11)$^{*}$
        \end{itemize}
        \item The set of binary strings which does not contain the substring $110$.
        \begin{itemize}
            \item 0$^{*}$(10+0)$^{*}$1$^{*}$
        \end{itemize}
        \item The set of binary strings containing the substring $010$ or $110$ (note: having both is acceptable).
        \begin{itemize}
            \item (0+1)$^{*}$(0+1)01(0+1)$^{*}$
        \end{itemize}
    \end{enumerate}
