前言 在比较排序的算法中,快速排序的性能最佳,时间复杂度是O(N*logN).因此,在使用比较排序时,时间复杂度的下限就是O(N*logN).而桶排序的时间复杂度是O(N+C),因为它的实现并不是基于比较实现的,而是基于映射函数实现的. 桶排序 桶排序工作的原理是将数组分到有限数量的桶子里.每个桶子再个别排序(有可能再使用别的排序算法或是以递归方式继续使用桶排序进行排序). 桶排序利用函数的映射关系,减少了几乎所有的比较工作.实际上,桶排序的f(k)值的计算,其作用就相当于快排中划分,已经把大量…

[5,10,1].sort(); 结果[1,10,5] 有点出人意料. array.sort( sortFunction )可选-指定如何比较元素顺序的函数名称 如果省略sortFunction参数,元素将按ASCII字符顺序的升序进行排列. // 根据元素转换为字符串后的字符长度进行升序排列function arraySortByLength(a, b){    // 为便于用户理解,此处未考虑a或b为undefined或null的情况.    var aStr = a.toString(),…

Array.sort()方法将数组中的元素排序并返回排序后的数组. 当不带参数时,默认按照顺序排序,也就是从小到大.当然,也可以直接给sort加一个比较函数比较. ,,]; arr.sort(); console.log(arr); //[1,4,7] arr.sort(function(a,b){ return a-b; //从小到大 }); console.log(arr); //[1,4,7] arr.sort(function(a,b){ return b-a; //从大到小 }); c…

Array.Sort可以实现便捷的字典排序,但如果完全相信他,那么就容易产生些异常!太顺利了,往往是前面有坑等你. 比如:微信接口,好多地方需要签名认证,签名的时候需要用的字典排序,如果只用Array.Sort()会出现签名异常的情况,而且是偶尔出现. 问题就在于他的排序默认没有区分大小写,这跟微信的签名将不匹配,所以还是需要自己实现比较的方法 public class DictionarySort : System.Collections.IComparer { public int Comp…

对数组中的元素进行排序. 此方法按 Unicode 值排序. (ASCII 是 Unicode 的一个子集.) 默认情况下,Array.sort()按以下方式进行排序: 1. 排序区分大小写(Z优先于a). 2. 按升序排序(a优先于b). 3. 修改该数组以反映排序顺序:在排序后的数组中不按任何特定顺序连续放置具有相同排序字段的多个元素. 4. 元素无论属于何种数据类型,都作为字符串进行排序,所以 100 在 99 之前,这是因为 "1" 的字符串值小于 "9"…

一些非比较排序 在LeetCode中有个题目叫Maximum Gap.是求一个非排序的正数数列中按顺序排列后的最大间隔.这个题用桶排序和基数排序都能够实现.以下说一下桶排序.基数排序和计数排序这三种非比較排序. 桶排序 这样的排序的主要思想是.把数列分配到多个桶中,然后再在各个桶中使用排序算法进行排序.当然也能够继续使用桶排序. 如果数组的最大值是A,最小值是B,长度是L,则每一个桶的大小能够是S=Max(1,(A-B)/(L-1))则能够分为(A-B)/S+1个桶. 对于数列中的数字x.用(x…

1.js的Array.sort()是使用什么算法排序: 1.火狐中是“归并排序” 2.V8引擎是 “插入排序和快速排序结合”.数组长度不超过10时,使用插入排序.长度超过10使用快速排序.在数组较短时插入排序更有效率. 2.各种算法 下图来自文章 各种排序实现以及稳定性分析 归并排序: 最好情况:O(nlogn)最坏情况:O(nlogn)平均情况:O(nlogn) 归并排序需要一个与原数组相同长度的数组做辅助来排序空间复杂度:O(n)稳定性:稳定(归并排序是稳定的排序算法,temp[i++] =…
