+%\section{Introduction}
+%
+%The \texttt{mluexercise} class is a template class for solving weekly exercises at the Institute for Computer Science of Martin Luther University Halle-Wittenberg.\footnote{\url{https://uni-halle.de/}}
+%The class can be used by all students---especially first semesters---to typeset their exercises with a low-effort in beautiful \LaTeX{}.
+% We include a bunch of handy macros that are used throughout many lectures during the bachelor's degree program.
+%
+%\changes{v1.0}{2018/10/03}{Initial draft}
+%\changes{v2.0}{2020/11/12}{First public release}
+%
+%\section{Usage}
+%
+%\DescribeMacro{\documentclass}
+%Load the \texttt{mluexercise} class at the start of your preamble.
+%
+%\iffalse
+%<*example>
+%\fi
+\begin{lstlisting}[gobble=4]
+ \documentclass{mluexercise}
+\end{lstlisting}
+%\iffalse
+%</example>
+%\fi
+%
+%\paragraph{Languages}
+%
+%As in many classes, you can define your main document language.
+%This will help \LaTeX{} in hyphenating words and structural texts (e.g.,~sections) are being translated automatically.
+%
+%\DescribeMacro{english}
+%The \texttt{english} option selects English language for texts and hyphenation.
+%
+%\DescribeMacro{ngerman}
+%The \texttt{ngerman} option selects German language (with new spelling) for texts and hyphenation.
+%
+%While you do not have to specify a language, it is a meaningful information for writers (including yourself) to explicitly state the desired language that should be used consistently throughout the whole document. If no language is specified, English language is used.
+%
+%\paragraph{Styles}
+%
+%\DescribeMacro{dataminingstyle}
+%The \texttt{dataminingstyle} option may be used for the \textquote{Data Mining} lecture and overwrites some mathematical symbols to match the lecture's definition's.
+%
+%\subsection{Exercise Metadata}
+%
+%Define the exercise's metadata and your identity. The below macros should be used only in the preamble, that is before \lstinline|\begin{document}|.
+%
+%\DescribeMacro{\lecture}
+%The \cs{lecture}\marg{name} macro sets the name of the lecture you are writing exercises for.
+%
+%\DescribeMacro{\semester}
+%The semester is automatically set to the current semester. You can overwrite the default value with the \cs{semester}\marg{semester} macro if you are compiling exercises for another semester.
+%
+%\DescribeMacro{\exercise}
+%The \cs{exercise}\marg{number} macro sets the number of the exercise you are working on.
+%
+%\DescribeMacro{\task}
+%The \cs{task}\marg{number} macro sets the number of the first task.
+%This is useful if you submit single PDF files for each task within the exercise.
+%If you omit this option, numbering starts at~1.
+%
+%\DescribeMacro{\group}
+%Sometimes tutors allow to submit exercises in groups.
+%You can use the optional \cs{group}\marg{number} macro to set the group number.
+%If no group number is given, the group number is not displayed.
+%
+%\DescribeMacro{\title}
+%The \cs{title}\marg{lecture name} macro is an alias for \cs{lecture}\marg{lecture name}.
+%
+%\DescribeMacro{\date}
+%The date is automatically set to the current date.
+%You can overwrite the default value with the \cs{date}\marg{date} macro.
+%
+%\subsection{Student Metadata}
+%
+%The following commands should be used to include identification in your exercise in order to assign your work.
+%
+%\DescribeMacro{\studentname}
+%You must define your full name with the \cs{studentname}\marg{full name} macro.
+%If you are working in a group, you can enter more names separated with commas and/or line breaks.
+%
+%\DescribeMacro{\studentnumber}
+%The \cs{studentnumber}\marg{matriculation number} macro specifies your student matriculation number (e.g.,~234\,567\,890). This is the same number as on your student ID card.
+%
+%\DescribeMacro{\studentsymbol}
+%The \cs{studentsymbol}\marg{shorthand symbol} macro specifies your shorthand symbol used for university IT services (e.g.,~abcde). This is the same username used for Stud.IP, university mail etc.
+%
+%Both \cs{studentnumber} an \cs{studentsymbol} are optional.
+%Though, most tutors require specifying either student number or symbol.
+%
+%\paragraph{Multiple Students}
+%
+%While you can use commas and line breaks in the above macros, we would suggest one of the following two options to submit work in groups with multiple students:
+%\begin{itemize}
+% \item Either use the services offered by the university to check-in your group members online~(e.g.,~in the Institute for Computer Science's \textquote{Übungsportal}).
+% In this case you don't need to specify multiple names in the preamble, but just your own name.
+% \item Or, if you cannot specify group members elsewhere, we recommend to add a footnote on the first page. That way you can list all other students but do not waste too much paper.
+%\end{itemize}
+%
+%\subsection{Included Packages}
+%
+%The \texttt{\jobname} class loads a number of useful \LaTeX{} packages listed in Table~\ref{tab:packages}.
+%Those are needed to typeset exercises during the Computer Science bachelor's degree programme at Martin Luther University Halle-Wittenberg.
+%We recommend reading the introductions of each package's documentation on CTAN\footnote{\url{https://ctan.org/}}.
+%\begin{table}
+% \caption{Packages included in the class.}
+% \label{tab:packages}
+% \begin{tabular}{lll}
+% \toprule
+% \textbf{Package} & \textbf{Purpose} & \textbf{Link} \\
+% \midrule
+% \texttt{babel} & hyphenation, localization & {\smaller\url{https://ctan.org/pkg/babel}} \\

+% \end{tabular}
+%\end{table}
+%
+%\section{Design Goals}
+%
+%The \texttt{\jobname} class should:
+%
+%\begin{itemize}
+% \item be usable for first semester students with rather little LaTeX experience,
+% \item be consistent with Martin Luther University brand guidelines\footnote{\url{https://www.pr.uni-halle.de/download/logo/}}, especially with respect to font families and colors, and
+% \item include packages frequently needed by students.
+%\end{itemize}
+%
+%\section{Implementation}
+%
+%\subsection{Setup}
+%
+%We specify the \LaTeX{} version, define and parse options and then load the base class \texttt{scrartcl}\footnote{\url{https://ctan.org/pkg/scrartcl}} with all remaining options.
+%
+% \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{mluexercise}[2020/11/12 v2.0]
+% \end{macrocode}
+%
+%\paragraph{Options}
+%
+% \begin{macrocode}
+\newif\ifdataminingstyle\dataminingstylefalse
+\DeclareOption{dataminingstyle}{%
+ \dataminingstyletrue
+}
+% \end{macrocode}
+%
+%Process options and load base class with remaining options.
+%
+% \begin{macrocode}
+\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrartcl}}
+\ProcessOptions*
+\LoadClass{scrartcl}
+% \end{macrocode}
+%
+%To enable support for UTF8 and some other useful basics, we load a bunch of packages.
+%
+% \begin{macrocode}
+\RequirePackage[utf8]{inputenc}
+\RequirePackage[T1]{fontenc}
+\RequirePackage{ifthen} % Conditional branches and loops.
+\RequirePackage{etoolbox} % Hooks for executing code.
+\RequirePackage{hyperref} % Hyperlinks.
+\RequirePackage{xcolor} % Color definitions.
+% \end{macrocode}
+%
+%As we'd like to be able to switch between English and German with proper hyphenation, load language support packages.%
+%\footnote{If you'd like to add a language, please contact us.}
+%
+% \begin{macrocode}
+\RequirePackage{babel}
+\RequirePackage{iflang}
+\newcommand{\IfGerman}[2]{\IfLanguagePatterns{german}{#1}{%
+ \IfLanguagePatterns{ngerman}{#1}{#2}}}
+% \end{macrocode}
+%
+%\subsection{Global Variables}
+%
+%The class can be configured with the lecture's and student's details. We define global variables for that and redefine some built in \LaTeX{} commands to ease the migration from standard classes.
+%
+% \begin{macrocode}
+\newcommand{\@checkoption}[3]{%
+ \AtEndPreamble{%
+ \ifthenelse{\equal{\the#1}{}}{%
+ \ClassError{mluexercise}{Missing #2}{%
+ Set #2 using the \protect#3 command.%

+}
+\newtoks\@lecture
+\newcommand{\lecture}[1]{\global\@lecture{#1}}
+\let\title\lecture % Redefine standard \title command.
+\@checkoption{\@lecture}{lecture name}{\lecture}
+\newtoks\@semester

+%
+%\subsection{Layout, Text}
+%
+%Set up a reasonable page layout and define text styles that comply with Martin Luther University brand guidelines.
+%
+% \begin{macrocode}

+]{geometry}
+\renewcommand{\baselinestretch}{1.15}
+\setlength{\parindent}{0em} % Disable paragraph indentation.
+\setlength{\parskip}{1ex} % Instead enable paragraph margins.
+% \end{macrocode}
+%
+%\paragraph{Font Families}
+%
+%We use Libertine as main font as that is the closest free font to the proprietary URW~Classico font used by the university. For mathematics we use the more modern Euler~Maths font and for source code the \emph{true} monospace font Source~Code~Pro, as otherwise copying from the PDF is broken. For clarity reasons we do not want code ligatures.

+%
+%We rely on AMS packages for rendering mathematical equations, proofs, and symbols.
+%Additionally we load packages for arrays in math mode and cancellations
+%

+\RequirePackage{amsmath}
+\RequirePackage{amsthm}
+\RequirePackage{amssymb}
+\RequirePackage{amstext}
+\RequirePackage{array}
+\RequirePackage{cancel}
+% \end{macrocode}
+%
+%Now we define (more readable) macros for the mathematical symbols and functions most commonly used at Martin Luther University.
+%
+% \begin{macrocode}
+\newcommand{\union}{\cup}
+\newcommand{\disjunction}{\uplus}
+\newcommand{\intersection}{\cap}
+\newcommand{\intersect}{\cap}
+\newcommand{\infinity}{\infty}
+\newcommand{\corresponds}{\triangleq}

+\newcommand{\rationalnumbers}{\Q}
+\newcommand{\Z}{\mathbb{Z}} % Whole numbers.
+\newcommand{\wholenumbers}{\Z}
+\newcommand{\N}{\mathbb{N}} % Natural numbers.
+\newcommand{\naturalnumbers}{\N}
+\newcommand{\B}{\mathbb{B}} % Binary numbers.

+%
+% \begin{macrocode}
+\newcommand{\mland}{\(\land\)} % \land in text.
+\newcommand{\mlor}{\(\lor\)} % \lor in text.

+%
+%Many maths symbols can have alternatives for stylistic choices. We enable the variants most liked by our tutors.
