Could anyone give a hint about Test 12? What does it look like? Some possible overflow, etc. My program returns correct answer on 10000 10000 test.

@Admins, can you please provide me with JUST an answer for this test? If so, my e-mail: dostoyevsky_at_ukr.net.

Thanks a lot.

Got AC. Made a mistake in printing long number — need no print leading zeros for non-top parts of number
