LeetCode之Sort List 1.问题描述 Sort a linked list in O(n log n) time using constant space complexity. 2.翻译 1 在固定的空间复杂度中使用O(nlog n)的时间复杂度进行链表的排序。 3.思路分析 提起排序,我们脑海中会迅速出现各种排序算法:冒泡排序、快速排序、简单排序、堆排序、直接插
first.next=null;//这里容易出现问题,提前将后置节点归null ListNode head1=sortList(head); ListNode head2=sortList(tmp);returnmergeList(head1, head2); }publicstaticvoidmain(String[] args){ LinkedSort linkedSort=newLinkedSort(); ListNode head1=newListNode(9); head1.next=newListNode(3); head1...
https://leetcode.com/problems/insertion-sort-list/ 题目: Sort a linked list using insertion sort. 思路: 头插法。用头结点可以简化插入链表时候的操作,因为要考虑插入链表中间和表头两种情况,插入表头时,head就要更新,还要判断pre指针是否为空 算法: public ListNode insertSortList(ListNode head, ListNode t)...
Leetcode: Insertion Sort List 题目:Sort a linked list using insertion sort. 即使用插入排序对链表进行排序。 思路分析: 插入排序思想见《排序(一):直接插入排序 》 C++参考代码: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) ...
Leetcode-Sort List Description Sort a linked list in O(n log n) time using constant space complexity. Explain 看题目要求,第一个是链表,第二个是时间复杂度为O(n log n),空间复杂度为O (1)。排序算法中说到这个时间复杂度的话,肯定也就会想到快排和归并排序。归并排序如果用数组实现的话,是做不到...
