Fast. Heap sort runs in time, which scales well as n grows. Unlike quicksort, there's no worst-case complexity. Space efficient. Heap sort takes space. That's way better than merge sort's overhead. Weaknesses: Slow in practice. While the asymptotic complexity of heap sort makes it...
POJ 2166 Heapsort(递推) Description A well known algorithm called heapsort is a deterministic sorting algorithm taking O(n log n) time and O(1) additional memory. Let us describe ascending sorting of an array of different integer numbers.The algorithm consists of two phases. In the first ph...
Here's an example: heap_sort_strings.php <?php function heapSortStrings(array &$arr): void { $n = count($arr); for ($i = (int)($n / 2) - 1; $i >= 0; $i--) { heapifyStrings($arr, $n, $i); } for ($i = $n - 1; $i > 0; $i--) { [$arr[0], $arr[$...

Problem Given an integer array, sort it in ascending order. Use quick sort, merge sort, heap sort or any O(nlogn) algorithm. Example Given[3, 2 , 1, 4, 5], return[1 , 2, 3, 4, 5]. Note 考察对Heap Sort, Quick Sort, Merge Sort的掌握。

but it can be a problem when we sort complex types, like objects. For example, imagine we have a custom class Person with the age and name fields, and several objects of that class in an array, including a person called "Mike" aged 19, and "David", also aged 19 - appearing in ...
The heap data structure is basically used as a heapsort algorithm to sort the elements in an array or a list. These algorithms can be used in priority queues, order statistics, Prim's algorithm or Dijkstra's algorithm, etc. As learned earlier, there are two categories of heap data structur...
