Leetcode-Sort List Sort a linked list inO(nlogn) time using constant space complexity. Analsys: We use Merge Sort. NOTE: We should practice other sort algorithm, linke Quick Sort and Heap Sort! Solution: 1/**2*
Sort a linked listinO(n log n) timeusingconstant space complexity. 这题的时间复杂度要求是O(n logn),很容易想到用mergeSort来解。 /*** Definition for singly-linked list. * class ListNode { * int val; * ListNode next; * ListNode(int x) { * val = x; * next = null; * } * }*/p...
Sort a linked list in O(n log n) time using constant space complexity. 本题就是考察的是链表的归并排序。 代码如下: /*class ListNode { int val; ListNode next; ListNode(int x) { val = x; } }*/ public class Solution { public ListNode sortList(ListNode head) { return mergeSort(head);...
【Leetcode】Sort List https://leetcode.com/problems/sort-list/ 题目: Sort a linked list in O(n log n) time using constant space complexity. 思路: 用归并排序,难点在递归划分链表中点。本题解答参考了网络答案。 算法: public ListNode sortList(ListNode head) { if(head==null||head.next==null...

总结: Merge Sort, LinkedList, Recursion 刚写代码,一个很久以前的朋友突然找我,上来第一句话就是, 以后去哪里发展? 很有社会上的口气。我就和他聊了开来,一开始是有提防心的,比如他问我在不在家,之类的,我都回避,但聊着聊着就聊开了。某人估计又要骂我傻逼了吧。
