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);}}}
