The problem is to give two sequences, the first one is the pre-order, the second is in the sort, and the next is the sequence in which it is sorted, sorted, and output.The feature of the insertion sort is that the front is arranged from small to large, followed by the same as the original sequence.The feature of heap sorting is that the following is the largest n
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
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 In this article, we describe the
]; currentsize=0; Maxsize=n; public boolean insert (int x) {if (currentsize==maxsize) {System.out.println ("Sorry,this heap Full! "); return false; //If a heap of discontent currentsize++; int flag=currentsize-1; while (flag>0) {int parent= (flag-1)/2; if (heap[parent]>x) {
Heap sorting is a sort of tree selection, which is an effective improvement on direct selection Sorting.Basic Idea:The heap is defined as follows: a sequence with n elements (k1,k2,..., kn), when and only if it satisfiesis called a heap. As can be seen from the definition of a heap
Select sortHow it works: each time the largest or smallest element is selected from the data element to be sorted, it is stored at the beginning of the sequence until all the data elements to be sorted are exhausted.Voidselectsort (int*a,size_tsize) {assert (a); for (inti=0;iHeap Sortonly needAscending Voidadjustdown (int*a,size_tsize,introot) { ASSERT (a);intchild=root*2+1; while (childThis article from "Write Quality or Low" blog, declined reprint!Sort
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

dealing with static data.For example: Select the top 100 in 100 million elements?Abstract: Select the first m element in n elements?The easy-to-think solution is to sort the n elements and then pick the first m elements. The time complexity is O (NLOGN).But if we use the priority queue, then our time complexity will be up to O (NLOGM).If the data to be processed is large, then the use of the priority queue will make the whole process more than 10 tim
Heap sort Ah, actually is a data structure, binary tree, binary tree is divided into two fork tree and complete binary tree. A depth of k, and there are 2k-1 nodes called full two fork tree, complete binary tree: The depth of k, there are n nodes of the two-tree, when and only if each of its nodes with a depth of k in the full two-tree with a number of 1 to n nodes corresponding to the node, called a comple

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 sort contains two steps: The first step: is to establish a large top heap (from large to small sort) or a small top heap (from little to large sort), from the bottom up; When the hea
Heap Sort Inserts all the elements into a priority queue that inserts a lookup for the smallest element, repeating the call to delete the smallest element, so that all elements are sorted in ascending order. Two stages of heap sequencing Heap Order Data order All elements are arranged in ascendi
Heap sort heap sort pre-tree with two fork treeTree is a very common non-linear data structure, called tree structure, referred to as tree. The so-called data structure is a collection of datasets together with their storage relationships and how they are manipulated. The tree structure is like the structure of a tree

Heap sorting is a sort of selection algorithm, which is independent of the initial order of keywords, that is, in the best, worst, general case, the comple
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 Sort::sink (int* A, const int root, const int end) {int I=root;while (2*i +1
