You can assume that except for the number 0, neither of these numbers will start with 0. 示例: 输入:(2 -> 4 -> 3) + (5 -> 6 -> 4) 输出:7 -> 0 -> 8 原因:342 + 465 = 807 Java解法1: publicclassSolution {publicListNode addTwoNumbers(ListNode l1, ListNode l2) { ListNode d...
【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. Input: (2 -> 4 ->...

Add Two Numbers 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. Input: (2 -> 4 -> 3) + (5 -> 6 -> 4) Output: 7 ...
public ListNode addTwoNumbers(ListNode l1, ListNode l2) { ListNode result = new ListNode(0); ListNode tem = l1; ListNode tem2 = l2; ListNode current = result; boolean flag = false; while (tem != null || tem2 != null) { // 计算节点值之和,需要判空 int sum = (tem != null ?
三、更优方案: 此处有更好更简洁的解决方案供参考::Leetcode – Add Two Numbers (Java)。该方法分别判断两个链表是否到链尾了。就不需要像一那样考虑多种情况,似乎很多问题都可以有将各种情况统一的方式。下次做之前要多思考是否有这种方式。
Leetcode 2 Add two numbers 链表求和 (Java) 程序员吉米 软件工程师题目 两个非空链表,表示两个非负整数。数字以相反的顺序存储,每个节点包含一个数字。添加两个数字并将其作为链接列表返回。 您可以假设这两个数字前面不包含任何零,除了数字0本身。
Java 代码如下: class Solution { public ListNode addTwoNumbers(ListNode l1, ListNode l2) { ListNode dummy = new ListNode(0); ListNode cur = dummy; int carry = 0; while (l1 != null || l2 != null || carry != 0) { int i1 = l1 != null ? l1.val : 0; ...
