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) {...
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) ...
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...

Given the head of a singly linked list, sort the list using insertion sort, and return the sorted list's head. The steps of the insertion sort algorithm: Insertion sort iterates, consuming one input element each repetition and growing a sorted output list. At each iteration, insertion sort ...
