Nettet22. jun. 2024 · A LeftList Heap also known as a LeftList Tree is a priority queue implemented with a variant of a binary heap. A binary heap provides insertion in O (log n) and deletion in O (log n) but suffers from O (n log n) merges. A leftList heap provides the advantage that it offers merging in O (log n). 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.
