下面的方法是,索性从dummy开始,重新组成一个list,所以这里dummy没有接在head后面。但实际上,由于链表的特点,即使不是in-place的,也不需要占新的内存。 代码比上面我的方法清晰很多。 /*** Definition for singly-linked list. * public class ListNode { * int val; * ListNode next; * ListNode(int x) {...
Linked lists have a pointer to the next element (in case of a singly linked list) and a pointer to the previous element as well (in case of a doubly linked list). Hence it becomes easier to implement insertion sort for a linked list. Let us explore all about Insertion sort in this t...

leetcode: Insertion Sort List 问题描述: Sort a linked list using insertion sort. 原问题链接:https://leetcode.com/problems/insertion-sort-list/ 问题分析 这里因为是针对链表进行插入排序,其过程和普通数组的插入排序有点不一样。相对来说因为没有直接的索引访问,它要复杂不少。在针对链表的插入排序实现...
