题目:Mergeksorted linked lists and return it as one sorted list. Analyze and describe its complexity. 解析:合并k个已经有序的单链表,使其最终成为一个有序的单链表。原理就是归并排序,递归运算。基本算法recusion 与 merge 编码: publicListNode mergeKLists(ListNode[] lists) {if(lists ==null|| lists...
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 ...
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. 1.解题思路 合并两个有序链表,同样需要构造一个Dummy节点。 1)考虑特殊情况,如果有一个链表为空,则直接返回另一个链接; ...
Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity. 1.解题思路 这题是Merge Two Sorted Lists的拓展,我们当然也可以利用两两归并来实现,但这里我们采用PriorityQueue实现更简洁清晰。 最小堆,队列顶端的元素永远是最小的,那我们把k个列表的第一个元素放入队列...
