+\begin{itemize}
+\item Make sure the files you submit can be processed by just calling\\
+  \mbox{\texttt{scala <<filename.scala>>}} on the commandline. Use the
+  template file provided and do not make any changes to arguments of
+  functions or to any types. You are free to implement any auxiliary
+  function you might need.
+
+\item Do not use any mutable data structures in your
+submission! They are not needed. This means you cannot create new 
+\texttt{Array}s or \texttt{ListBuffer}s, for example. 
+
+\item Do not use \texttt{return} in your code! It has a different
+  meaning in Scala than in Java.
+
+\item Do not use \texttt{var}! This declares a mutable variable. Only
+  use \texttt{val}!
+
+\item Do not use any parallel collections! No \texttt{.par} therefore!
