1. I have to talk about Binary Trees.To understand the heap, you must first understand the binary

This article mainly introduced the PHP sorting algorithm heap sorting (heap sort), combined with the example form detailed analysis of the heap sequencing principle, implementation methods and related use considerations, the need for friends can refer to the following

1. Heap Sort DefinitionN-keyword sequences kl,k2,...,kn called heaps, when and only if the sequence satisfies the following properties (referred to as heap properties):(1) Ki≤k2i and Ki≤k2i+1 or (2) ki≥k2i and ki≥k2i+1 (1≤i≤)If the vector stored by this sequence is R[1..N] as a storage structure of a complete binary tree, the

1. Heap sorting not only has the same time complexity as the merge sort O (NLGN), but also the space complexity occupies an extra number of elements space, this has the advantage of inserting sort.2. Heap sorting is divided into 3 parts, the first part is the function of preserving the nature of the

the heap, it is necessary to the current unordered area (R1,R2,...... Rn-1) is adjusted to the new heap, and then again R[1] is exchanged with the last element of the unordered area to get the new unordered area (R1,R2 ...). Rn-2) and a new ordered region (RN-1,RN). Repeat this process until the number of elements in the ordered area is n-1, the entire sort proc

Heap sorting is an efficient algorithm using heap sequencing, which can realize O (nlogn) Sorting time complexity, and the algorithm can analyze the time complexity of heap sorting algorithm.Algorithm implementation:To adjust the heap:void

during the transformation process. If the number element of the maximum heap is n, then build-max-heap starts with Parent (n) and then calls Max-heapify. The process is as follows:
Described in JavaScript are as follows:
function Buildmaxheap (array, heapsize) {
var i,
iparent = Math.floor ((heapSize-1)/2);
for (i = iparent i >= 0; i--) {
maxheapify (array, I, heapsize);
}

, let's take a look at this article. Other algorithms that perform more efficiently, such as merge sorting, such as fast sorting, heap sorting, and so on.1. Merge sort Let's take a look at what the merge sort is and how the merge sort is implemented.Merge sort belongs to a

Heap sorting is a sort of in-place sorting algorithm that does not use extra array space and runs at O (NLGN). In this article, we will introduce the implementation of heap sequencing.To understand heap sequencing, let's begin by understanding a concept, a completely binary

binary tree, satisfies any node is smaller than its child node; Features: Minimal elements appear on the root nodeNote: When the left and right subtree of the root node is a heap, but itself is not a heap, it can be transformed into a heap by a downward adjustment. Heap sort

Quick sort each time the comparison takes O (n), to make a lgn comparison, the entire sort is finally completed. So the complexity of the fast line is only O (N*LGN). In this section, we are going to talk about heap sorting algorithms. As far as I know, to really thoroughly understand an algorithm, it is best to find t

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:
Realize#heapclass

is a merge of two already sequenced sub-arrays.However, when an array is merged, it needs to be copied into the array of the new request, and the copy process takes time and additional memory overhead.2.
