https://oj.leetcode.com/problems/merge-two-sorted-lists/ 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. ===Comments by Dabay=== 基本链表的操作。先做一个头节点,用两个指针来记录两个链表的...
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 利用链表的思想,先创建个空链表p,用于存放比较后的结果。然后对传入的两个链表...
我的github连接:https://github.com/princewen/leetcode_python 21. Merge Two Sorted Lists Merge Two Sorted Lists 很简单的链表拼接题,但是要注意两个地方 1、返回值要返回head.next 2、无需判断循环后哪个不为空,or返回第一个为真的值 # Definition for singly-linked list. # class ListNode(object): #...
Merge Two Sorted Lists 二、解题 两个有序链表的排序。 三、尝试与结果 classSolution(object):defmergeTwoLists(self,l1,l2):ret=ListNode(0)ifl1==None:returnl2ifl2==None:returnl1ifl1.val<l2.val:ret=l1 ret.next=self.mergeTwoLists(l1.next,l2)else:ret=l2 ...
Merge Two Sorted Lists 合并两个已排序的链表,新链表中的每个节点必须是来自输入的两个链表的节点(即不能构造新的节点),返回新链表的头部。 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。 示例: 输入:1->2->4, 1->3->4 输出:1->1->2->3->4->4 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/merge-two-sorted-lists ...
用一个大小为K的最小堆(用优先队列+自定义降序实现)(优先队列就是大顶堆,队头元素最大,自定义为降序后,就变成小顶堆,队头元素最小),先把K个链表的头结点放入堆中,每次取堆顶元素,然后将堆顶元素所在链表的下一个结点加入堆中。 代码语言:javascript ...
