The test suite already spoils the solution.
True. In general that should be avoided, although admittedly it's difficult here because if the correct answer were hard-coded, then changes to: (i) the hardware on which Cody runs; or (ii) the version of MATLAB that Cody employs may eventually invalidate it. Having said that, the Test Suite could still be tightened up (see e.g. Solution 1461085).
