So is Heap Sort really so bad?Heap Sort has advantages and disadvantages when compared with any other top-notch algorithm.Vs. Merge Sort Heap sort makes more comparisons than merge sort. This is why it loses the competition in the video. Heap sort uses less memory. As shown in the video...

In this paper, we present a new mergesort algorithm which can sort n(= 2h+1 − 1) elements using no more than n log2(n+1) − (1312)n − 1 element comparisons in the worst case. This algorithm includes the heap (fine heap) creation phase as a pre-processing step, and for ...
首先, heapify 是 O(n) 的,但是堆排序不是 O(n) 的。heapify 只是堆排序的一步而已,heapify 将一个数组整理成堆的形式,但是一个堆不是一个排序数组,从一个堆到一个排序数组,需要一个过程,请再理解一遍堆排序的整个过程。堆排序算法也是 O(nlogn) 的。 其次,是的,堆排序虽然时间复杂度也是 O(nlogn) ...
