> {{checkAnswer}} doesn't handle {{Map\[K, V\]}} properly. For example:
> {noformat}
> scala> Map(1 -> 2, 2 -> 1).toString
> res0: String = Map(1 -> 2, 2 -> 1)
> scala> Map(2 -> 1, 1 -> 2).toString
> res1: String = Map(2 -> 1, 1 -> 2)
> {noformat}
> We can't rely on {{toString}} to compare {{Map\[K, V\]}} instances.
> Need to update {{checkAnswer}} to special case {{Map\[K, V\]}}.
