一、题目名称java
Merge Two Sorted Lists(按升序拼接两个有序链表)node
二、题目地址code
https://leetcode.com/problems/merge-two-sorted-lists/ci
三、题目内容leetcode
英文:Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists.开发
中文:给定两个已经排好序(升序)的链表,将它们拼接成一个新的有序(升序)链表get
四、解题方法it
本题的解决方法比较比较简单明了,Java代码以下:io
/** * @功能说明:LeetCode 88 - Merge Two Sorted Lists * @开发人员:Tsybius2014 * @开发时间:2015年11月16日 */ public class Solution { /** * 按升序拼接两个有序链表 * @param l1 链表1 * @param l2 链表2 * @return */ public ListNode mergeTwoLists(ListNode l1, ListNode l2) { ListNode start = new ListNode(0); ListNode result = start; while (l1 != null || l2 != null) { if (l1 == null || (l1 != null && l2 != null && l1.val >= l2.val)) { result.next = new ListNode(l2.val); result = result.next; l2 = l2.next; } else { result.next = new ListNode(l1.val); result = result.next; l1 = l1.next; } } return start.next; } }
