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) {...
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 ...

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. ...
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; ...

Representation If there is only one sentinel node then the list is circularly linked via the sentinel node. It can be concept as two singly linked list formed from the same data item, but in opposite sequencial order Structure of node doubly linked list is a list that contains lin...
