[002-Add Two Numbers (单链表表示的两个数相加)] 原题 You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. In
import java.util.ArrayList; import java.util.List; //一个数如果恰好等于它的因子之和,这个数就称为"完数".例如6=1+2+3.第二个完全数是28, //它有约数1.2.4.7.14.28,除去它本身28外,其余5个数相加, //编程找出1000以内的所有完数. public class Test { public static void main(String[] args) { System.out.print("完数有
day11 --------------------------------------------------------------- 实例018:复读机相加 题目 求s=a+aa+aaa+aaaa+aa-a的值,其中a是一个数字.例如2+22+222+2222+22222(此时共有5个数相加),几个数相加由键盘控制. 分析:很简单,字符串*x可以复制. 1 a = input('请输入数字:') 2 n = input("请输入要加几次:") 3 s = 0 4 for i in
给定一个int数字,把数字中的单个数相加起来:得到的结果如果不是个位数,继续相加 如给定 19,执行1+9 = 10 --> 1 + 0 = 1 返回1 给定22,返回4 思路很简单,把各个位置上的数字取出来相加:结果如果大于9,继续执行相加 Java代码实现: public class AddDigitsTotal { public static int addOnce(int n) { int result = 0; while (n != 0) { result += n%10; n =
