JavaScrip 排序算法(JavaScript Sorting Algorithms) 基础构造函数 以下几种排序算法做为方法放在构造函数里. function ArrayList () { var array = []; // 交换位置 var swap = function (index1, index2) { var aux = array[index1]; array[index1] = array[index2]; array[index2] = aux; } this.inser…

Recently I systematicall review some sorting algorithms, including insertion sort, bubble sort, merge sort and quick sort. I then implement them in C++. All the function takes in a  vector<int>& type and directly operates on the input. To use th…

Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort. Time Complexity: O(N^2) f…

*稳定指原本数列中相同的元素的相对前后位置在排序后不会被打乱 快速排序(n*lgn 不稳定):数组中随机选取一个数x(这里选择最后一个),将数组按比x大的和x小的分成两部分,再对剩余两部分重复这个算法直到结束.但在数据量小的时候表现差. def quick_sort(a) (x = a.pop) ? quick_sort(a.select{|i| i <= x}) + [x] + quick_sort(a.select{|i| i > x}) : [] end 冒泡排序(n^2 稳定):如果a…

如果具有同样关键字的纪录的在排序前和排序后相对位置保持不变.一些算法本身就是稳定的,如插入排序,归并排序,冒泡排序等,不稳定的算法有堆排序,快速排序等. 然而,一个本身不稳定的算法通过一点修正也能变成稳定的算法.有一些特定的方式可以做到,一般来说,任何排序算法中的比较本质上都是不稳定的,通过修改关键的比较操作,充分考虑两个比较单位相等的情况,都可以将算法变得稳定.…

Merge sort by using recursive strategy, i.e. divide and conquer. def merge(left,right): result = [] i,j =, while i < len(left) and j < len(right): if left[i]<right[j]: result.append(left[i]) i += else: result.append(right[j]) j += result += left[…

1306. Sorting Algorithm Constraints Time Limit: 1 secs, Memory Limit: 32 MB Description One of the fundamental problems of computer science is ordering a list of items. There're a plethora of solutions to this problem, known as sorting algorithms. So…

More important than algorithms(just problems #$!%), the techniques/concepts residing at the base of such algorithms is more important. There are broadly 4 ways in which classification of algorithms can be done. Classification by purpose Each algorith…
