Your last test case is accidentally all commented out, so isn't a real test case
The question is unclear. Do the factor-numbers all have to be two-digited?
@Jan-Andrea Bard, no.
Although it is not mentioned clearly in the problem statement but you can see a hint from the test suite
This problem would be really fun with larger test cases. It would eliminate kron() and stop naively checking every string combination.
@Brandon you could submit a new problem ("Palindromic Numbers - Hard Mode" or so).
