In computer science, an AVL tree is a self-balancing binary search tree, and it was the first such data structure to be invented.

( This is in contrast to splay tree lookups, which do modify their tree's structure.

* Binary tree, a computer tree data structure in which each node has at most two children

In computer science, a binary tree is a tree data structure in which each node has at most two child nodes, usually distinguished as " left " and " right ".

In a language with records and references, binary trees are typically constructed by having a tree node structure which contains some data and references to its left child and its right child.

Binary trees can also be stored in breadth-first order as an implicit data structure in arrays, and if the tree is a complete binary tree, this method wastes no space.

In computer science, a B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time.

It was Darwin and his contemporaries who first linked the hierarchical structure of the great tree of life in living organisms with the then very sparse fossil record.

Modern paleontology has joined with evolutionary biology to share the interdisciplinary task of unfolding the tree of life, which inevitably leads backwards in time to the microscopic life of the Precambrian when cell structure and functions evolved.

( This assumes that the code tree structure is known to the decoder and thus does not need to be counted as part of the transmitted information.

Usually all Internet e-mail is transmitted in MIME format, allowing messages to have a tree structure where the leaf nodes are any of a variety of single part content types and the non-leaf nodes are any of a variety of multipart types.

If a more sophisticated data structure ( e. g., heap or binary tree ) is used, the time required for searching and insertion can be reduced significantly ; this is the essence of heap sort and binary tree sort.

* Bethe lattice, a regular infinite tree structure

Since it is a balanced tree, it guarantees insertion, search and delete to be O ( log n ) in time, where n is the total number of elements in the tree.

A skip list, upon which we have not recently performed either of the above mentioned Θ ( n ) operations, does not provide the same absolute worst-case performance guarantees as more traditional balanced tree data structures, because it is always possible ( though with very low probability ) that the coin-flips used to build the skip list will produce a badly balanced structure.

The fruit is allowed to mature on the tree, but it is still firm at this point.

Just because a tree or other object appears in a certain spot is absolutely no reason to place it in the same position in the painting, unless the position serves the design of the whole composition.

Now the thing for us to do is to find ourselves a couple of those wonderful flowering currants such as the red Ribes sanguineum of our Pacific Northwest, or otherwise a good sloe tree, or perhaps some nice pussy willow in bloom, preferably one with male or staminate catkins.

This is in honor of John Ledyard, class of 1773, who scooped a canoe out of a handy tree and first set the course way back in his own student days.

Coffee is made from the roasted and ground seeds of the coffee tree.

" The state tree is the Longleaf Pine, the state flower is the Camellia.

Apollo as a handsome beardless young man, is often depicted with a kithara ( as Apollo Citharoedus ) or bow in his hand, or reclining on a tree ( the Apollo Lykeios and Apollo Sauroctonos types ).

Young of the Cuban tree frog ( Osteopilus septentrionalis ) can occasionally be cannibalistic, the younger tadpoles attacking a larger, more developed tadpole when it is undergoing metamorphosis.

The granular poison frog ( Oophaga granulifera ) is typical of a number of tree frogs in the poison dart frog family Dendrobatidae.

The usually nocturnal Cuban tree frog ( Osteopilus septentrionalis ) produces a rain call when there is rainfall during daylight hours.

Less can be said about the Asterales themselves with certainty, although since several families in Asterales contain trees, the ancestral member is most likely to have been a tree or shrub.

The phylogenetic tree presented below is based on Panero & Funk ( 2002 ).

), is a species of tree native to the Middle East and South Asia.

" Almond " is also the name of the edible and widely cultivated seed of this tree.

The almond is a small deciduous tree, growing in height, with a trunk of up to in diameter.

The calcium carbonate dust is a respiratory irritant and the particles can penetrate into the lower respiratory tree and cause irritant bronchitis and other respiratory irritation responses.

Amber is fossilized tree resin ( not sap ), which has been appreciated for its color and natural beauty since Neolithic times.

It is thought that, in addition to exuding onto the surface of the tree, amber resin also originally flowed into hollow cavities or cracks within trees, thereby leading to the development of large lumps of amber of irregular form.

Both the Latin and the Germanic words derive from the Proto-Indo-European root el -, meaning " red " or " brown ", which is also a root for the English words " elk " and another tree: " elm ", a tree distantly related to the alders.

Old Norse askr literally means " ash tree " but the etymology of embla is uncertain, and two possibilities of the meaning of embla are generally proposed.
