     5 \begin{itemize}

     6 \item Make sure the files you submit can be processed by just calling\\

     7   \mbox{\texttt{scala <<filename.scala>>}} on the commandline.\footnote{All

     8     major OSes, including Windows, have a commandline. So there is no

     9     good reason to not download Scala, install it and run it on your

    10     own computer. Just do it!} Use the

    11   template files provided and do not make any changes to arguments of

    12   functions or to any types. You are free to implement any auxiliary

    13   function you might need.

    14 

    15 \item Do not use any mutable data structures in your

    16 submissions! They are not needed. This means you cannot create new 

    17 \texttt{Array}s or \texttt{ListBuffer}s, for example. 

    18 

    19 \item Do not use \texttt{return} in your code! It has a different

    20   meaning in Scala, than in Java.

    21 

    22 \item Do not use \texttt{var}! This declares a mutable variable. Only

    23   use \texttt{val}!

    24 

    25 \item Do not use any parallel collections! No \texttt{.par} therefore!

    26   Our testing and marking infrastructure is not set up for it.

    27 \end{itemize}

    34 It should be understood that the work you submit represents

    35 your \textbf{own} effort! You have not copied from anyone else. An

    36 exception is the Scala code I showed during the lectures or

    37 uploaded to KEATS, which you can freely use.\bigskip
