Ned Gulley submitted a Comment to Problem 2883. prime test

Hi Ritwik: Cody is most interesting when you can give a problem where the answer changes with the input. Can you rework this so that one single number doesn't answer the problem?

Ned Gulley submitted a Comment to Problem 2692. design a magic matrix without using the command magic.

Hi Anumpam: Thanks for the problem. You need to fix the test suite as James says. Also, since you haven't specified what order you want the numbers in, you should probably check to make sure the matrix has magic properties (rows add to the same number, etc.) rather than testing that it matches exactly one matrix. There are lots of magic 4-by-4 matrices.
