I figured out a very simple algoritham (and quick-0.02sec)
but I get Wrong Answer. I've been testing it even on
large N & K  (8,8), and it works fine (gives the correct
answer). Can anybody help me????
Thanks

I solved this problem by counting all the combinations.
It works properly for N+K<=18.

hm-m... try to check you algorithm for the simpliest case -
1 digit in 10-based system. your alrogithm may answer 9,
though the correct answer is 10 :)
