Hello, I am using the following code for Problem 3199 and it is not working.  Can you please let me know what I am doing wrong.


#include <iostream>
using namespace std;

int main()
{
     int n,d, i, j;
     long int V[10][26];

	for (j=1; j <= 10; j++)
	{
	 	for (i=0; i <= 25; i++) 
		  {
			  V[j-1][i]=1;
			  if (i!=0) 
				  V[j-1][i] =V[j-1][i-1] * j;
			  else 
				  V[j-1][i]=j;
		  }

	}
	while(scanf("%d %d",&n,&d)!=EOF)
    {
		if (n==0 && d==0) goto end;
		else printf("%d\n",V[n-1][d-1]);
	}
end:
	return 0;
}
