“堆”的入门知识 一种特殊的二叉树——堆(Binary Heaps) 堆是具有以下两种特性(限制)的二叉树。 一、属于完全二叉树(complete binary tree) 二、每个节点的值必须大于或等于(或者小于等于)子节点的值 首先看下完全二叉树的定义:除最底层节点外,所有层节点都完全填充且必须从左侧开始填充。简单说就是节点必须从...
Full and almost fullbinary heapsmay be represented in a very space-efficient way using anarrayalone. The first (or last) element will contain the root. The next two elements of the array contain its children. The next four contain the four children of the two child nodes, etc. Thus the ...
Binary heapsPeriodic networksWe consider the problem of constructing binary heaps on constant degree networks performing compare-exchange operations only. The heap data structure, introduced by William and Williams [Comm. ACM 7 (6) (1964) 347–348], has many applications and, therefore, has been ...
Binary heaps come in two flavours; the min-heap which allowsO(logn)O(\log n)O(logn)extraction of the minimum element, and the max-heap which allows the same for the maximum value. Before it is possible to extract values, the heap must first be constructed. This is done by running an...

iheap -- a single-header C++ template for indexed binary heaps An indexed binary heap supports both O(1) lookup of the in-heap index and O(log n) update of the element value, for any element in the heap. This is achieved by augmenting each heap operation with the corresponding updates...
