我的程序:::::
#include <iostream>
using namespace std;

int main()
{
	double n, m;
	while (scanf("%lf%lf", &n, &m)==2, n!=0)
	{
		double w = n<m ? n:m;
		double ans=1.0, i;
		for (i=1; i<=w; i+=1)
			ans *= ((n+m-i+1)/i);
		printf("%.0lf\n", ans);
	}

	return 0;
}
----------------------------
#include < iostream >
using namespace std;
double com (double n,double m)
{
	double i;
	double result(1);
	if ( n >= m - n ){ n = m-n; }
	for ( i = m;i >= m-n+1;i-=1 )
	{
		result *= (i / (i - (m - n)));
	}
	return result;
}
int main()
{
	double n,m;
	while (1)
	{
		scanf("%lf%lf",&n,&m);
		if ( n==0 && m==0 ){ break; }
		printf("%.0lf\n",com (n,m+n));
	}
	return 0;
}
