I think answer to test case #4 is correct, though #5 and #6 are incorrect.

Can you clarify what is the answer you are getting for 5 & 6.
So far I can tell, they are correct. Others have also solved it nicely.

Results from Wolfram alpha -
#5 = 8

#6 = 1036

You can also use symbolic or BigInteger and show they are incorrect.

Okay. I see. Maybe I missed something - gotta look at the theories. I will do that later.
