100！ 不知道对不对啊，反正查0的个数是对的
程序代码：
import java.math.BigInteger ;
public class firstgui
{
public static void main(String[] args)
{
BigInteger result = new BigInteger("1");
for (int i = 1; i <= 100; i++)
{
BigInteger num = new BigInteger(String.valueOf(i));
result = result.multiply(num);
}
System.out.println(result);
}
}
