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...

Java [leetcode 2] Add Two Numbers 问题描述: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....
You may assume the two numbers do not contain any leading zero, except the number 0 itself. Input: (2 -> 4 -> 3) + (5 -> 6 -> 4) Output: 7 -> 0 -> 8 题意: 给你两个表示两个非负数字的链表。数字以相反的顺序存储,其节点包含单个数字,将这两个数字相加并将其作为一个链表返回。

You may assume the two numbers do not contain any leading zero, except the number 0 itself. Follow up: What if you cannot modify the input lists? In other words, reversing the lists is not allowed. Example: Input: (7 -> 2 -> 4 -> 3) + (5 -> 6 -> 4) ...
