Heap_Sort,Shell_Sort and Quick_Sort 介绍三种排序,堆排序、希尔排序和快速排序。 首先是堆排序:一个有n个记录的线性序列{R1,R2,R3,...Rn},其关键字序列{K1,K2,...,Kn} 满足{Ki<=K2i Ki<=K(2i+1)}或者是大于等于 那么就称之为堆。如果用一课完全二叉 来表示堆的话,就是说该树中的非叶子结点...

Vs. Quick Sort On average, quick sort is about as fast as merge sort, and much faster than heap sort. If we measure not the average performance, but the worst case performance, that is, the worst possible time it would take the algorithm to finish, then heap sort is far better than...
Heap Sort vs Quick SortHeap sort and quick sort are both efficient sorting algorithms with O(n log n) average time complexity. However, they have different characteristics. Quick sort is generally faster in practice due to better cache performance and smaller constant factors. However, heap sort...
