This problem is an interactive problem, as such there are no output files. 

The interactor works by taking the input given through the STDIN stream and outputting its responses to the STDOUT stream, with the exit code signalling whether the solution was correct or not.

There is no easy way to automate this through terminal scripting, so we leave the interactor only for reference.

If you would like to test your code, we recommend you submit it to one of the online judges that has uploaded the problem:
