 \noindent
-\textbf{Important:} Do not use any mutable data structures in your
-submissions! They are not needed. This means you cannot use 
-\texttt{ListBuffer}s, for example. Do not use \texttt{return} in your
-code! It has a different meaning in Scala, than in Java.
-Do not use \texttt{var}! This declares a mutable variable. Make sure the
-functions you submit are defined on the ``top-level'' of Scala, not
-inside a class or object. Also note that the running time of
-each part will be restricted to a maximum of 360 seconds on my laptop.
