heap sort algorithm in c

before self-study data structure of the time to see the C language version of the four basic sorting method, C language is almost forgotten, recently available in PHP four sort method to re-write again, review the increasingly unfamiliar algorithm. Paste the code directly. "; Print_r ($var); echo "";} $arr =array (33,11,22,66,55,44,88,99,77);p rintf ("* * Original array * *");p($arr);/*** Bubble

the time complexity of O (N) sorting algorithm: The algorithm of Time Complexity O (N) has cardinal sort, counting sort, but both of them need to know the range of the elements in advance so as to build the number of buckets, so it is not appropriate to solve this problem. Exclude! 2, for the time comple

Heap sort and quick sort, merging sort are all the common sorts of time complexity O (N*LOGN). Before learning heap sorting, first explain what is the data structure of the two-fork heap. The definition of a binary

First, prefaceIf you need a Java version of the heap ordering or the basics of heap sorting-the concept of a tree, see my blog "Sorting algorithm (ii) heap sorting"Questions about choosing a sortThe problem of choosing the most sort is not knowing whether the sorted data is

); }}Four-heap sorting algorithmInitially, the heap sorting algorithm uses BUILD-MAX-HEAP to build the largest heap of input array arr[0...n-1]. Because the largest element in the array is always in the root node arr[0], by swapping it with arr[n-1], we can put the elemen

Topic Information1098. Insertion or Heap Sort (25)Time limit (MS)Memory Limit 65536 KBCode length limit 16000 BAccording to Wikipedia:Insertion sort iterates, consuming one INPUT element each repetition, and growing a sorted output list. Each iteration, insertion sort removes one element from the input data, finds the

The heap can be regarded as a complete two-fork tree, with the exception of the lowest level, where each layer is full, which allows the heap to be represented by an array, with each node corresponding to an element in the array. The relationship between the array and the heap: Binary heaps are generally divided into two types: maximum

One, what is a heapA heap is a complete binary tree with the following properties. Each node is greater than or equal to the value of its left and right child nodes, called the Big Top heap.Or the value of each node is less than or equal to the value of the left and right child nodes, called the small top heap.Second, if you sort by heapAs defined by the heap, th

The previous article summarizes the bubble sort and quick sort of the interchange sort. This article summarizes the selection of sorting, the choice of sorting is divided into direct selection of sorting and heap sorting, mainly from the following points to summarize.1. Direct selection sequencing and

million, but if you remove the duplicates, no more than 3 million. The higher the repetition of a query string, the more users are queried for it, the more popular it is, please count the hottest 10 query strings, which requires no more than 1G of memory.Solution: Although there are 10 million query, but because of the high repetition, so in fact only 3 million of the query, each query255byte, (300w*255b Hash statistics: This batch of massive data preprocessing (maintain a key for the

The previous article used the Quicksort method to sort, but if the rapid sorting method for high repetition rate of slice, time complexity will soar, the speed is quite slow, so try to heap sorting, experimental results, feel very good. Here is the code, you can refer to, This is the building of the big top pile. Two fork tree features: Last Non-leaf node: root = LENGTH/2 (root down rounding when length is
