CSC378: Leftist Trees
Leftist Tree Definition. A "leftist tree" is an implementation of a mergeable heap. In a binary tree, define an external node to be one with fewer than two children. Define dist ( i ) to be the number of edges on the shortest path from node i to a descendant external node. A leftist tree is a binary tree with properties.

Leftist Heaps A leftist heap is a heap-ordered binary tree which has a very special shape called a leftist tree. One of the nice properties of leftist heaps is that is possible to merge two leftist heaps efficiently. As a result, leftist heaps are suited for the implementation of mergeable priority queues.

Binomial heaps Abinomial heap H is aset of binomial treesthat satisﬁes the following binomial heap properties: 1 Each binomial tree in H isheap-ordered: the key of a node is greater than or equal to the key of its parent. 2 There is at most one binomial tree in H …
Fill In The Missing Details Of A Heap Based Data | Chegg.com
Fill in the missing details of a heap based data structure known as leftist heaps or mergeable heaps. The mathematical objects involved are multi-sets of items of type ItemType. (A multi-set is a collection of items in which there may be multiple copies of a single item.) Every item has a key of type KeyType, and these keys are linearly ordered ...

In this paper we develop the skew heap, a self-adjusting form of heap related to the leftist heaps of. Crane and Knuth. (What we mean by a heap has also been called a “priority queue” or a “mergeable. heap”.) Skew heaps use less space than leftist heaps and similar worst-case-efficient data structures and are.

1.1 Sequential Mergeable Priority Queues Many theoretically- and practically-e cient sequential implementations exist for mergeable priority queues. Leftist heaps were among the rst to support all operations in worst case O(logn) time by using a balanced binary tree structure of size n[Cra72]. Binomial heaps
