Because we only traverse one branch of all the children at each rung of the tree, we achieve () runtime, where N is the total number of keys stored in the leaves of the B+ tree. [ 4 ] function search( k , root ) is let leaf = leaf_search(k, root) for leaf_key in leaf.keys(): if k = leaf_key: return true return false
A star tree is a tree which consists of a single internal vertex (and n – 1 leaves). In other words, a star tree of order n is a tree of order n with as many leaves as possible. A caterpillar tree is a tree in which all vertices are within distance 1 of a central path subgraph.
A k-path is a k-tree with at most two leaves, and a k-caterpillar is a k-tree that can be partitioned into a k-path and some k-leaves, each adjacent to a separator k-clique of the k-path. In this terminology, a 1-caterpillar is the same thing as a caterpillar tree, and k-caterpillars are the edge-maximal graphs with pathwidth k. [6]
It is a fast-growing, short-lived tree with opposite, ash-like compound leaves. It is sometimes considered a weedy or invasive species , and has been naturalized throughout much of the world, including South America , Australia , New Zealand , South Africa , much of Europe , and parts of Asia .
For an m-ary tree with height h, the upper bound for the maximum number of leaves is . The height h of an m-ary tree does not include the root node, with a tree containing only a root node having a height of 0. The height of a tree is equal to the maximum depth D of any node in the tree.
As a result, = + also holds for a full binary tree. To make a binary tree with a leaf node without its sibling, a single leaf node is removed from a full binary tree, then "one leaf node removed" and "one internal nodes with two children removed" so = + also holds. This relation now covers all non-empty binary trees.
A planar graph and its minimum spanning tree. Each edge is labeled with its weight, which here is roughly proportional to its length. A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight.

Pinus jeffreyi is a large coniferous evergreen tree, reaching 25 to 40 meters (82 to 131 ft) tall, rarely up to 53 m (174 ft) tall, though smaller when growing at or near tree line. [5] The leaves are needle-like, in bundles of three, stout, glaucous gray-green, 12 to 28 centimeters ( 4 + 3 ⁄ 4 to 11 in) long. [ 6 ]
