WA3 guess xeus 9 авг 2011 03:54

As far as I guess, the right answer for WA3 is zero. And it comes up when, for instance, you have "N=2" and "S=38". Four bits cannot produce the sum more then thirty six, you know.

My answers are same for all the test cases you have written here.
My recursive formula is m[len][sum] = m[len-1][sum-k] for 0<=k<=9.
Then why is it showing wrong anwser for test case 2.
