HeapSort From a max heap First, we swap the first element and last element, and rebuild the max heap of the elments except the last element. To do such thing in the new max heap until there is only one element.1 2 3 4 5 6 7 int a[10]={4,1,3,2,16,9,10,14,8,7}; ...
Heap Sort是高级排序算法中能保证O(nlogn)时间界的和O(1)空间界的少数算法之一(还有两个是Inplace Merge Sort和堆排序的改进版Smooth Sort),在理论上是一个相当完美的算法。但由于堆排序所需比较次数较多,而且在比较、交换元素的时候也是大范围跳跃的,所以速度并不是很快。 1#include<cstdio> 2#include<cstdlib...

1. 插入排序—直接插入排序(Straight Insertion Sort) 基本思想: 将一个记录插入到已排序好的有序表中,从而得到一个新且记录数增1的有序表。即:先将序列的第1个记录看成是一个有序的子序列,然后从第2个记录逐个进行插入,直至整个序列有序为止。 要点:设立哨兵,作为临时存储和判断数组边界之用。 直接插入排序...
