The algorithm works the same way but compares strings instead of numbers. Descending Order SortingTo sort in descending order, we modify the heapify function to create a min heap instead of a max heap: heap_sort_descending.php <?php function heapSortDescending(array &$arr): void { $n = ...
Sorting Algorithm Quick reference Complexity Worst case time O(nlgn)O(nlgn) Best case time O(n)O(n) Average case time O(nlgn)O(nlgn) Space O(1)O(1) Strengths: Fast. Heap sort runs in O(nlg(n))O(nlg(n)) time, which scales well as nn grows. Unlike quicksort,...

5. Max Heap Sort VariantsWrite a C program to sort numbers using the MAX heap algorithm.Note: A sorting algorithm that works by first organizing the data to be sorted into a special type of binary tree called a heap.Sample Solution:
This section describes the Heap Sort algorithm - A complex and fast sorting algorithm that organizes original collection into a heap which is a binary tree with every node higher that its children in order, then repeatedly takes the root node to the end

algorithm ch6 heapsort 堆排序利用的是堆这种数据结构来对进行排序,(二叉)堆可以被视为一棵完全的二叉树,树的每个节点与数组中存放该节点的值得那个元素对应。这里使用最大堆进行排序算法设计,最大堆就是parent(i) > leftchild(i) 且parent(i) > rightchild(i),首先利用迭代法进行建堆。
