Very nice problem!
How do you return two separable outputs via a single vector?
Christopher, I should have been more clear in the problem description.
There are two outputs to the function. The first output (how_many) is a scalar, and is the number of circular primes.
The second output (what_numbers) is the vector containing the values of the circular primes.
Does this help?
197 is not circular prime, because neither 791 nor 917 are themselves prime. Only test case 2 is correct.
Christopher, if our number is represented as ABC, then a cicrular prime is a number where ABC, BCA, and CAB are all prime. You are either shifting the numbers in the opposite direction or scrambling them. Not every permutation of the numbers has to be a prime number, although that in itself would be an interesting Cody problem. :-)
