The output of * operator in this solution is a struct, rather than a mPoly object. Nevertheless, the test suite does not check the type of the output.
L Y Cao, since you're such a wizard with indices, I'd love to see you solve this without converting to the array form. It would be interesting to compare the approaches.
Andrew Newell, thanks for your advice.
