In this article, we explain the heap sort algorithm in Python. We cover sorting numeric and textual data in both ascending and descending order. Finally, we compare heap sort with quick sort and perform a bench
输入A导致输出30、11、16、12、14、17、18、19、20、25。该实现基于“算法基础”(:Neapolitan,Richard第五版)中的算法7.5,我尝试将其直接转换为python。在下面加一些沥青。 任何建议都是有帮助的! 书中的算法如下: 我试着在纸和笔上找出打嗝的地方,但似乎还是找不出. Stack ...
Heap Sort is a sorting algorithm based on the binary heap data structure in which first we have to find the maximum element from the array, and then it will be replaced by the end element. Then, we will perform heapify on our heap, for maintaining the heap property. We will follow thes...
Now let’s actually begin the real steps in sorting our array using Python Heap Sort. But first, a small explanation. If you paid attention to the code and it’s explanation, then you’ll have some idea on how this sorting process will look. Basically, we check the children of each no...

Also since the build_max_heap and heap_sort steps are executed one after another, the algorithmic complexity is not multiplied and it remains in the order of nlog n. Also it performs sorting in O(1) space complexity. Compared with Quick Sort, it has a better worst case ( O(nlog n) ...
