While solving the exercises a couple of weeks ago I found that the code wasn't indented correctly (see image below, that belongs to these exercises). Later I found that there was a syntax error in the Scala code displayed. This PR solves it, and hopefully (I guess it wasn't displayed correctly because of the syntax error) it will also fix the indentation of the code.
