10. 二叉堆(Binary Heap) 二叉堆是完全二叉树(或者近似完全二叉树);其满足堆的特性:父节点的值>=(<=)任何一个子节点的键值,并且每个左子树或者右子树都是一个二叉堆(最小堆或者最大堆);一般使用数组构建二叉堆,对于array[i]而言,其左子节点为array[2*i],其右子节点为array[2*i+1];二叉堆支持插...
Given two binomial heaps H1, and H2 BINOMIAL_HEAP_UNION(H1, H2) creates a single binomial heap. First, we simply merge two heaps in increasing order of degrees. After that, we need to make sure there is at most one Binomial tree of any degree so that we combine binomial trees of the...
As stated above, binomial heap is the collection of binomial trees, and every binomial tree satisfies the min-heap property. It means that the root node contains a minimum value. Therefore, we only have to compare the root node of all the binomial trees to find the minimum key. The time ...
