学习golang难免需要分析源码包中一些实现,下面就来说说container/heap包的源码 heap的实现使用到了小根堆,下面先对堆做个简单说明 1. 堆概念 堆是一种经过排序的完全二叉树,其中任一非终端节点的数据值均不大于(或不小于)其左孩子和右孩子节点的值. 最大堆和最小堆是二叉堆的两种形式. 最大堆:根结点的键值是所有堆结点键值中最大者. 最小堆:根结点的键值是所有堆结点键值中最小者. 2. heap 树的最小元素在根部,为index 0. heap包对任意实现了heap接口的类型提供…

堆排序虽然叫heap sort,但是和内存上的那个heap并没有实际关系.算法上,堆排序一般使用数组的形式来实现,即binary heap. 我们可以将堆排序所使用的堆int[] heap视为一个完全二叉树,即,除非最后一层右侧有空结点,其他都为满结点. 对于任意heap[i]有如下一些性质: 1. i从1开始. 2. heap[i]的父节点为heap[i / 2]. 3. heap[i]的左子节点为heap[i * 2],右子节点为heap[i * 2 + 1]. 我们假设这个堆是一个最大堆,…

堆排序(heap sort) 具体解释 及 代码(C++) 本文地址: http://blog.csdn.net/caroline_wendy 堆排序包括两个步骤: 第一步: 是建立大顶堆(从大到小排序)或小顶堆(从小到大排序), 从下往上建立; 如建堆时, s是从大到小; 第二步: 是依次交换堆顶和堆底, 并把交换后的堆底输出, 仅仅排列剩余的堆, 从上往下建立; 如构造时, s始终是1; 堆排序(Heap Sort)的时间复杂度是O(nlogn), 最坏情况下也是如此. 而高速排序(Quic…

堆排序(Heap Sort)具体步骤为 将无序序列建成大顶堆(小顶堆):从最后一个非叶子节点开始通过堆调整HeapAdjust()变成小顶堆或大顶堆 将顶部元素与堆尾数组交换,此是末尾元素就是最大值,顶部元素不满足堆,故要将顶部元素在剩余的i-1个元素中调整为堆 反复第2步.直至所有顶点被输出,序列变成从小到大的有序序列 C语言实现(编译器Dev-c++5.4.0,源代码后缀.cpp) 原创文章,转载请注明来自钢铁侠Mac博客http://www.cnblogs.com/gangtiexia #…

题目就是给两个序列,第一个是排序前的,第二个是排序中的,判断它是采用插入排序还是堆排序,并且输出下一次操作后的序列. 插入排序的特点就是,前面是从小到大排列的,后面就与原序列相同. 堆排序的特点就是,后面是从小到大排列的最大的几个数p~n-1,前面第一位则是p-1. 所以只要先按照插入排序的特点来判断是否为插入排序,接下来再进行操作就可以了,这里要手动写下最大堆的更新操作. 代码: #include <iostream> #include <cstdio> #include <…

PAT甲级1098. Insertion or Heap Sort 题意: 根据维基百科: 插入排序迭代,消耗一个输入元素每次重复,并增加排序的输出列表.在每次迭代中,插入排序从输入数据中删除一个元素,在排序列表中找到它所属的位置,并将其插入到其中.它重复,直到没有输入元素保留. 堆排序将其输入分成排序和未排序的区域,并且通过提取最大的元素并将其移动到排序的区域来迭代地缩小未排序的区域.它涉及使用堆数据结构而不是线性时间搜索来查找最大值. 现在给出整数的初始序列, 连同一些序列,这是一些排序方法…
