Merge two sorted linked lists and return it as a new sorted list. The new list should be made by splicing together the nodes of the first two lists. Input: l1 = [1,2,4], l2 = [1,3,4] Output: [1,1,2,3,4,4] 方法一、递归 publicListNode mergeTwoLists(ListNode l1, ListNode l2...
You are given the heads of two sorted linked lists list1 and list2. Merge the two lists in a one sorted list. The list should be made by splicing together the nodes of the first two lists. Return the head of the merged linked list. Example 1: Input: list1 = [1,2,4], list2 =...
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. 将两个升序链表合并为一个新的升序链表并返回。新链表是通过拼接给定的两个链表的所有节点组成的。 Example: Input:1->2->4,1->3->4Output:1->1-...

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. 合并2个有序链表 2、代码实现 /** * Definition for singly-linked list. * public class ListNode { ...
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. Example: Input:1->2->4, 1->3->4Output:1->1->2->3->4->4 思路: 合并两个有序链表,做法有两种,递归和迭代,递归的条件就是返回两个节点中...
Specifies the maximum number of pages for each document. When the threshold is reached, a new document is created with the number of pages necessary to hold the remaining records being merged (up to the per-page limit). This option is available only when Multiple Records are selected from th...
