can complete all priority-queue operations within the time complexity of LGN.Application of heap: heap sortThe whole process is divided into
Build heap
Extract Maximum Value
Put it at the end of the sequence
Repeat guided sorting completeThe specific algorithm is as follows:

Heap Sort
Heap ordering is a sort of tree selection, which is an effective improvement of direct selection sort.Basic idea:The heap is defined as follows: A sequence with n elements (k1,k2,..., kn), if and only if satisfied
Case 1:ki Case 2:ki >= k2i and Ki >= k2i+1 (maximi

;}}Hill sortHill sort when inserting a sort of upgraded version, there is a descending increment sequence, which is generally sorted by the array size n, constantly pressing the increment div of N/2, each time comparing the number of increments between these numbers, the number of these several sorts;Time complexity uncertainty, instability, preferably O (N).void Shellsort () {int len = n;for (int div = LEN

A variety of common sortTo start looking for a job, the previous learning of a variety of small knowledge to review, the following is a variety of common sort of simple implementation (bubble sort, choose sort, insert sort, hill sort, he

Heap Sorting algorithmFirst look at the first function heapadjust, this function is already the composition of the heap of the two-fork tree, if the node K data changes, the node K is modified to make it a new heap binary tree, n is the data length.def heapadjust (lst,k,n): While (2*k+1The Heapsort function, using the first function above, constructs a

The first is the algorithm implementation file Sort.h, the code is as follows:/** implements eight commonly used sorting algorithms: Insert sort, bubble sort, select sort, Hill sort * and quick sort, merge sort,

The first is the Eightalgorithms.java file, the code is as follows:Import java.util.arrays;/* * Implements eight commonly used sorting algorithms: Insert sort, bubble sort, select sort, Hill sort * and quick sort, merge sort,

Heap Sort heap Sorting Algorithm and JavaScript code implementation, Heap heap sorting
1. I have to talk about Binary Trees.To understand the heap, you must first understand the binary tree. in computer science, a binary tree is a

Sort the arbitrarily populated array in piles, then delete the heap, because the heap is always the largest in the current heap, and according to this feature, you can get an ordered array(in piles) starts from the last parent node and adjusts downward to the topmost parent node.(delete

size of the left and right subtree.So, to design an ascending sort, we need to build a maximum heap.1) Build a maximum heap.2) for the 1th time, the element of the root node is exchanged with the last node element of the heap, so that the maximum element is guaranteed to be at the last node of the
