Insertion sort is a very intuitive algorithm as humans use this pattern naturally when sorting cards in our hands. In this lesson, using TypeScript / Javascript, we’ll cover how to implement this algorithm, why this algorithm gets its name, and the c…

来源:https://leetcode.com/problems/insertion-sort-list Sort a linked list using insertion sort. 方法: 1. 使用一个preHead指向头节点,这样在将节点插入头节点前面时(即某个节点值比头节点小)不需要进行特殊处理 2. 从头节点开始遍历,如果当前节点的下一个节点的值比当前节点的值大,就从头开始遍历找到第一个比当前节点的下一个节点的值大的节点,并插入到它的前面,注意插入时需要同时处理节点移出位置和插入位…

Sort a linked list using insertion sort. class Solution { public: ListNode *insertionSortList(ListNode *head) { if(head == NULL || head->next == NULL) return head; ListNode *result; result->val = INT_MIN; result->next = NULL; ListNode *cur=head,*…

对链表进行插入排序. 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链表中. 插入排序算法: 插入排序是迭代的,每次只移动一个元素,直到所有元素可以形成一个有序的输出列表. 每次迭代中,插入排序只从输入数据中移除一个待排序的元素,找到它在序列中适当的位置,并将其插入. 重复直到所有输入数据插入完为止. 示例 1: 输入: 4->2->1->3 输出: 1->2->3->4 示…

题目 Sort a linked list using insertion sort. 分析 实现链表的插入排序 注意: 程序入口的特殊输入判断处理! 节点的链接处理,避免出现断链! AC代码 /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNode(int x) : val(x), next(NULL) {} * }; */ class Solutio…

Sort a linked list using insertion sort. 链表的插入排序实现原理很简单,就是一个元素一个元素的从原链表中取出来,然后按顺序插入到新链表中,时间复杂度为O(n2),是一种效率并不是很高的算法,但是空间复杂度为O(1),以高时间复杂度换取了低空间复杂度.代码如下: /** * Definition for singly-linked list. * struct ListNode { * int val; * ListNode *next; * ListNod…

Sort a linked list using insertion sort. A graphical example of insertion sort. The partial sorted list (black) initially contains only the first element in the list.With each iteration one element (red) is removed from the input data and inserted in…

(PS:内容参考MIT算法导论) 插入排序(Insertion Sort): 适用于数目较少的元素排序 伪代码(Pseudocode): 例子(Example): 符号(notation): 时间复杂度(Running Time): 源代码(Source Code): #include<iostream> using namespace std; template<class T> void InsertSort(T a[], int n){ for(int j=1;j<n;…
