unit leftist heaps and binomial queues unit leftist heaps and binomial queues notes contents objectives introduction leftist heaps leftist trees implementation merging leftist heaps putting items into leftist heap removing items from leftist heap skew heaps binomial queues summary keywords self assessment review questions further readings objectives after studying this unityou will be able tostate the concept leftist heaps realise skew heaps explain the binomial queues introduction numerous data structures have been developed that can support efficient implementations of all the priority-queue operations most of them are based on direct linked representation of heap-ordered trees two links are needed for moving down the tree (either to both children in binary tree or to the first child and next sibling in binary tree representation of general treeand one link to the parent is needed for moving up the tree developing implementations of the heap-ordering operations that work for any (heap-orderedtree shape with explicit nodes and links or other representation is generally straightforward the difficulty lies in dynamic operations such as insertremoveand joinwhich require us to modify the tree structure different data structures are based on different strategies for modifying the tree structure while still maintaining balance in the tree leftist heaps leftist heap is heap-ordered binary tree which has very special shape called leftist tree one of the nice properties of leftist heaps is that is possible to merge two leftist heaps efficiently as resultleftist heaps are suited for the implementation of mergeable priority queues lovely professional university
