Sort a linked list in O(n log n) time using constant space complexity. 1.解题思路 题目要求时间复杂度为O(n log n),所以我们就想到用归并排序,自然就想到和上一题的mergeTwoLists。 但要做mergeTwoLists,必须得先将当前的list分割成两个List,所以采用递归实现。 要分割链表,最简单的办法就是找到中点,...
Write a Java program to merge the two sorted linked lists.Sample Solution:Java Code:import java.util.* public class Solution { public static void main(String[] args) { // Create two sorted linked lists ListNode list1 = new ListNode(1); list1.next = new ListNode(3); list1.next.next ...
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. 英文版地址 Loading...leetcode.com/problems/merge-...
Write a Java program to merge two sorted (ascending) linked lists in ascending order.Sample Solution:Java Code:// Importing the java.util package to use LinkedList, Scanner, ArrayList, and List import java.util.*; // Defining the Main class class Main { // Main method, the entry point ...
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. 依次拼接 复杂度 时间O(N) 空间 O(1) 思路 该题就是简单的把两个链表的节点拼接起来,我们可以用一个Dummy头,将比较过后的节点接在这个Dummy头之后。
本文将描述Merge k Sorted Lists的算法实现和分析。 算法题目:将K个排序好的链表合并。 算法思路: 1. 使用堆排序方式来合并链表 2. 使用合并两个链表的方法 算法复杂度分析:在两个算法实现之后会有相关分析。 二、算法实现: 1、推排序合并链表(java中的优先队列) ...
Input: list1 = [], list2 = [0] Output: [0] Java代码 publicstatic ListNodemergeTwoLists(ListNode l1,ListNode l2){ListNode dummy=newListNode(0);ListNode p=dummy;while(l1!=null||l2!=null){if(l2==null){p.next=l1;break;}if(l1==null){p.next=l2;break;}if(l1.val<l2.val){p.next...
Bothl1andl2are sorted in non-decreasing order. 合并两个有序链表。 给两个有序链表,请将两个链表merge,并且输出的链表也是有序的。思路很简单,就是用一个dummy node去遍历两个链表,然后比较两者的node.val。直接上代码。 时间O(m + n),两个链表的长度 ...
