Is there a reason why I needed to fflush( stdout ) in the sample interactive problem even though I printed a newline in the printf? When I run the code locally, it does flush automatically, as expected.

Without fflush: Idleness limit exceeded on test 1

With fflush: Accepted

Shouldn't they be equal? I am not sure if this is a misunderstanding on my behalf, or an issue in the interactor (at least for GNU C11).
