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. 递归实现: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(i…
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. 思路:使用伪头部 class Solution { public: ListNode *mergeTwoLists(ListNode *l1, ListNode *l2) { ListNode fakehead();…
1. 原题链接 https://leetcode.com/problems/merge-two-sorted-lists/description/ 2. 题目要求 给出两个已经从小到大排序的链表ls1.ls2,进行合并,合并后仍有序,返回合并后的链表 3. 解题思路 创建一个表头指针headPointer和一个定位指针locatePointer,headPointer用来保存头结点. 同时对ls1和ls2进行遍历,当ls1的值小于ls2的值时,locatePointer指向ls1,否则指向ls2…
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. 题目标签:Linked List 题目给了我们两个lists,让我们有序的合并两个 lists. 这题利用递归可以从list 的最后开始向前链接nodes,代码很简洁,清楚. Java Solution: Runti…
