heapsort在实践中的表现经常不如quicksort(尽管quicksort最差表现为Θ(n2)Θ(n2),但quicksort 99%情况下的runtime complexity为Θ(nlgn)Θ(nlgn)),但heapsort的O(nlgn)O(nlgn)的上限以及固定的空间使用经常被运作在嵌入式系统。在搜索或机器学习中经常也有重要的作用,它可以只返回k个排序需要的值而不管其他元素...

Heap Sort is an efficient, comparison-based sorting algorithm that uses a binary heap data structure to sort elements. It combines the speed of Quick Sort with the consistent performance of Merge Sort, making it an excellent choice for systems requiring guaranteed O(n log n) time complexity. ...
We regularly introduce new features to our users that they may not understand due to the complexity of our space. It's important to us to see who's using what and where they experience difficulty, which Heap has been very helpful in bringing some clarity to. Pros Funnel analysis User ...
Fast. Heap sort runs in O(nlg(n))O(nlg(n)) time, which scales well as nn grows. Unlike quicksort, there's no worst-case O(n2)O(n2) complexity. Space efficient. Heap sort takes O(1)O(1) space. That's way better than merge sort's O(n)O(n) overhead. Weaknesses: ...
Complexity analysis Time When we insert the elements of the array into the priority queue, we are doing O(N) = N · log N compares. When we delete the minimum element of the heap, we are doing O(N) = N · log N compares.
