题目:Sort a linked list using insertion sort,即仿照插入排序(直接插入排序)对一个链表排序。 插入排序的思想:总共进行n-1趟排序,在排列第i个元素时,前面的i个元素是有序的,将第i个元素插入到前i个元素中,并且保证被插入的数组是有序的,数组是顺序存储的,因此向有序的数组插入一个元素时,需要从插入位置之...
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 ...
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) ...
Algorithm of Insertion Sort: Insertion sort iterates, consuming one input element each repetition, and growing a sorted output list. At each iteration, insertion sort removes one element from the input data, finds the location it belongs within the sorted list, and inserts it there. It repeats...

一、题目描述对链表进行插入排序。 插入排序的动画演示如上。从第一个元素开始,该链表可以被认为已经部分排序(用黑色表示)。每次迭代时,从输入数据中移除一个元素(用红色表示),并原地将其插入到已排好序的…
