NettetA common way of implementing this idea is to use what is known as a leftist heap. A leftist heap is a binary tree that forms a heap such that for every node, the null path length of the right child is no more than the null path length of the left child. For such a structure, completing the merge algorithm is simple: NettetAlgorithm Visualizations

Leftist tree - Wikipedia

In computer science, a leftist tree or leftist heap is a priority queue implemented with a variant of a binary heap. Every node x has an s-value which is the distance to the nearest leaf in subtree rooted at x. In contrast to a binary heap, a leftist tree attempts to be very unbalanced. In addition to the heap property, leftist trees are maintained so the right descendant of each node has the lower s-value. Nettet28. mar. 2024 · A Computer Science portal for geeks.

Skew heaps are advantageous because of their ability to merge more quickly than binary heaps. In contrast with binary heaps, there are no structural constraints, so there is no guarantee that the height of the tree is logarithmic.
