前端需要掌握的算法之——插入排序(Insertion sort) Bad programmers worry about the code. Good programmers worry about data structures and their relationships. ——Linus Torvalds 插入排序(Insertion sort)就是每一步都将一个待排序的元素,按照它的大小,插入到已经排序的元素中的适当位置,一直重复,直到全部待排...
【JAVA代码实现】 publicstaticvoidmain(String[]args){int[]arr={5,6,3,1,8,7,2,4};sort(arr);}publicstaticvoidsort(int[]arr){if(arr.length<=1){return;}for(intj=1;j<arr.length;j++){intkey=arr[j];inti=j-1;while(i>=0&&arr[i]>key){arr[i+1]=arr[i];i--;}arr[i+1]=key...
Insertion sort uses N^2/4 compares and N^2/4 exchanges to sort a randomly ordered array of length N with distinct keys, on the average. The worst case is N^2/2 compares and N^2/2 exchanges and the best case is N-1 compares and 0 exchanges. 证明过程给出书中的原文: Proof: Justas...
Working of Insertion Sort Suppose we need to sort the following array. Initial array The first element in the array is assumed to be sorted. Take the second element and store it separately inkey. Comparekeywith the first element. If the first element is greater thankey, thenkeyis placed in...

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> usingnamespacestd; template<classT> voidInsertSort(Ta[],intn){
以及选择排序Selection Sort: 【Python入门算法9】如何实现选择排序 Selection Sort?2 赞同 · 0 评论文章 选择排序的算法原理: 选择排序是先选定左边第一个位置,然后将其它元素和第一个位置的元素进行对比,如果右边的某个元素更小,那么将该元素与第一个位置的元素交换。
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 {...
时间复杂度为O（n），而时间复杂度为O（n. log（n）），因此，在任何情况下，MergeSort的时间复杂...
