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…

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…
