Java大法好。退C保平安.......开玩笑的,Java和C各有各的优劣势,缺一不可!
我不会大数模版。就用BigInteger了,HDU大数水题不解释!
import java.io.*; import java.math.BigInteger; import java.util.*; public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); while(input.hasNext()) { int n = input.nextInt(); BigInteger p = BigInteger.ONE; for(int i=1;i<=n;i++) { p=p.multiply(BigInteger.valueOf(i)); } System.out.println(p); } } }
