Finger search tree
WebApr 3, 2024 · A finger search tree is a data structure that is designed to allow for efficient search and access of data in a set or a sequence. It is a type of binary search tree that … Ralf Hinze and Ross Paterson state a finger tree is a functional representation of persistent sequences that can access the ends in amortized constant time. Concatenation and splitting can be done in logarithmic time in the size of the smaller piece. The structure can also be made into a general purpose data structure by defining the split operation in a general form, allowing it to act as …

WebConsider two binary search trees with n nodes, one storing the even integers between 2 and 2 n, the other storing the odd integers between 1 and 2 n − 1. Merging the two trees creates a new binary search tree storing all integers between 1 and 2 n. In any such tree, a constant fraction of the nodes have different parity than their parents.

WebAug 28, 2024 · In computer science, finger search trees are a type of binary search tree that keeps pointers to interior nodes, called fingers. The fingers speed up searches, insertions, and deletions for elements close to the fingers, giving amortized O(log n) lookups, and amortized O(1) insertions and deletions.

WebJul 17, 2010 · Nearly all of the deques mentioned above are finger search trees as well. In a functional setting this means they can be split at the ith element in O(lg(min(i,n-i))) time and two trees of size n and m can be concatenated in O(lg(min(n,m))) time. I know of two ways of implementing deques that don't use trees. WebMany different search trees have been developed and studied intensively in the literature.
