【数据结构】三万字图文讲解带你手撕八大排序(附源码)4

8、计数排序8.1 算法思想思想：计数排序又称为鸽巢原理，是对哈希直接定址法的变形应用。我们先看一下计数排序的动图：计数排序实际上就是将数组中对应数据出现的次数，将数据出现次数映射到一个新数组中。在与数据相等值的下标处，将这个下标位置的元素自增。每出现一个数字就自增一次。而平常的映射就是直接在其相等...

6.6 缺陷分析及优化缺陷1：有序或接近有序序列时间复杂度过高其实对于快排来说，它的时间复杂度是不稳定的，比如上方三个版本，在乱序的序列中，效率可能还可以，因为选取的 k e y key key 值是随机的。但是对于有序序列，比如要排正序，但是序列是逆序。如果每次选 k e y key...

4、堆排序堆排序我们之前的文章已经详细讲解过，详情见这篇博客：【数据结构】堆的拓展延伸 —— 堆排序和 TopK问题其中时空复杂度我们也分析过：时间复杂度： O ( N × l o g N ) O(N \times log N) O(N×logN)，空间复杂度 O ( 1 ) O(1) O(1) ...
