WebbIt is straightforward to implement a mergeable heap given a simple heap: Merge (H1,H2): x ← Extract-Min (H2) while x ≠ Nil Insert (H1, x) x ← Extract-Min (H2) This can however be wasteful as each Extract-Min (H) and Insert (H,x) typically have to maintain the heap property . More efficient implementations WebbUsing Fibonacci heaps, binomial queues, or skew heaps, ﬁnd max (min), inserts and melds takeO(1) time (actual and amortized) and a delete max (min) takes O(logn) amortized time.

WebbA skew heap is a memory efficient, self-adjusting heap with an amortized performance of O (log n) or better. SkewHeap:PP is implemented in pure perl, yet performs comparably to SkewHeap. The key feature of a skew heap is the ability to quickly and efficiently merge two heaps together. Webb斜堆 (Skew Heap)基于左倾堆的概念，也是一个用于快速合并的堆结构，但它可自我调整 (self-adjusting)，每一个merge操作的平摊成本仍为 O (logN)，其中N为结点数，而且和左倾堆相比，每个结点没有npl属性，从而节省了空间。斜堆并不能保证左倾，但是每一个合并操作（也是采取右路合并）同时需要无条件交换（而左倾堆中只是根据左右子树的npl值 …

WebbA heap is a useful data structure when it is necessary to repeatedly remove the object with the highest (or lowest) priority, or when insertions need to be interspersed with removals of the root node.
