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

  \mbox{\texttt{scala <<filename.scala>>}} on the command line.\footnote{All

    major OSes, including Windows, have a command line. So there is no

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

    own computer. Just do it!} Use the

  template files 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 \textbf{Do not leave any test cases running in your code because this might slow

  down your program!} Comment out test cases before submission, otherwise you

  might hit a time-out.

\item Do not use any mutable data structures in your

submissions! 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. It changes the meaning of your program,

  and you should never use it.

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

  use \texttt{val}!

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

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

It should be understood that the work you submit represents

your \textbf{own} effort! You have implemented the code entirely

on your own. You have not copied from anyone else.

Do not be tempted to ask Github Copilot for help or

do any other shenanigans like this! An exception is the Scala

code I showed during the lectures or uploaded to KEATS,

which you can freely use.\bigskip
