身份证号码升级 15行！！！

解题思路:    位权数组modules,末位字符数组f,  按位权求和之后求余数，连接字符串

注意事项:    无

参考代码:

import java.util.Scanner;
public class Main {
	static String f[]= {"1","0","x","9","8","7","6","5","4","3","2"};
	static int modules[]= {7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2};
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		String s =in.next(),res=s.substring(0,6)+"19"+s.substring(6);
		int sum=0;
		for(int i=0;i<res.length();i++)
			sum+=(res.charAt(i)-'0')*modules[i];
		res+=(f[sum%11]);
		System.out.println(res);
		in.close();
	}
}
