Test problem 21 is faulty.
It has been updated.
Test suite has crashed again plz fix
@ Nikolaos: are you sure it's the test suite and not a server error? If you get the following message, it is due to a temporary server problem, not a specific problem: "While evaluating the solution, the server encountered an error caused by temporary unavailability of MATLAB Service. Wait a few minutes for the MATLAB Service to return, and then rescore." If you are getting this error, simply try the problem again later or on a different day.
