您可以假设除了数字 0 之外,这两个数都不会以 0开头。 Give two non-empty linked lists to represent two non-negative integers. Among them, their respective digits are stored in reverse order, and each node of them can only store one digit. If we add these two numbers together, we will ret...

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。
以下是我写的java程序: 一、常规做法: 逐一抽取计算,并考虑其中某个到达链尾的情况。 /** * Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(in x) { val = x; } * } */publicclassSolution{public ListNodeaddTwoNumbers(ListNode l1,ListNode...
You are given two non-empty linked lists representing two non-negative integers. 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, exc...
2. Add Two Numbers Question Description My Key package AddTwoNumbers; import java.util.Scanner; public class ListNodeMain { private static Scanner sc; public static void main(String[] args) { System.out.println("start ..."); ListNode l1 = new ListNode(0), tmpListNode1 = l1;...
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; ...
Problem You have two numbers represented by a linked list, where each node contains a single digit. The digits are stored in reverse order, such that the 1's digit is at the head of the list. Write a function that adds the two numbers and returns the sum as a linked list. ...
