If the node is a leaf or has only one child, remove it.

In languages with tagged unions such as ML, a tree node is often a tagged union of two types of nodes, one of which is a 3-tuple of data, left child, and right child, and the other of which is a " leaf " node, which contains no data and functions much like the null value in a language with pointers.

One simple representation which meets this bound is to visit the nodes of the tree in preorder, outputting " 1 " for an internal node and " 0 " for a leaf.

Each node or leaf in the tree has zero or more resource records, which hold information associated with the domain name.

A leaf node sends its QRT to each of the ultrapeers it is connected to, and ultrapeers merge the QRT of all their leaves ( downsized to 128 Ki-slots ) plus their own QRT ( if they share files ) and exchange that with their own neighbours.

Ultrapeers do that check before forwarding a query to a leaf node, and also before forwarding the query to a peer ultra node provided this is the last hop the query can travel.

These are usually the ultrapeers of a leaf node and they are announced in search results.

To save memory, sometimes a single sentinel node performs the role of all leaf nodes ; all references from internal nodes to leaf nodes then point to the sentinel node.

In many of the presentations of tree data structures, it is possible for a node to have only one child, and leaf nodes contain data.

For a black node with one null leaf child and one non-null-leaf child, properties 3, 4 and 5 ensure that the non-null-leaf child must be a red node with two black null leaves as children.

Whereas in the binary search tree, we always add a leaf, in the red – black tree leaves contain no information, so instead we add a red interior node, with two black leaves, in place of an existing black leaf.

* property 5 ( all paths from any given node to its leaf nodes contain the same number of black nodes ) is threatened only by adding a black node, repainting a red node black ( or vice versa ), or a rotation.

Directory items with too many entries or indirect items which are too long to fit into a node spill over into the right leaf neighbour.

If a link connecting a leaf fails, that leaf is isolated ; if a connection to a non-leaf node fails, an entire section of the network becomes isolated from the rest.

Years of patient application of compost and leaf mulching has changed the structure of the soil and its water-holding capacity.

Mr. Clark still has to use rotenone with potatoes grown on the least fertile fields, but he has watched the insect damage decrease steadily and hopes that continued use of compost and leaf mulch will allow him to do without it in the future.

Sanskrit nouns in this case often refer to a subject " out of " which or " from " whom something ( an action, an object ) has arisen or occurred — e. g., patram vṛkṣāt patati " the leaf falls from the tree ".

Bay leaf is also an antifungal and antibacterial, and has also been used to treat rheumatism, amenorrhea, and colic.

When a door has more than one movable section, one of the sections may be called a leaf.

These include the amount of light available, the amount of leaf area a plant has to capture light ( shading by other plants is a major limitation of photosynthesis ), rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying out photosynthesis.

Like most other Proteaceae, P. cynaroides has proteoid roots, roots with dense clusters of short lateral rootlets that form a mat in the soil just below the leaf litter.

The living aura theory is at least partially repudiated by demonstrating that leaf moisture content has a pronounced effect on the electric discharge coronas ; more moisture creates larger, more dynamic corona discharges.

The olive tree, Olea europaea, has been cultivated for olive oil, fine wood, olive leaf, and the olive fruit.

The oil has a strong flavour with a hint of green leaf.

Flat-leaved parsley is preferred by some as it is easier to cultivate, being more tolerant of both rain and sunshine, and has a stronger flavor ( though this is disputed ), while curly leaf parsley is preferred by others because of its more decorative appearance in garnishing.

A third type, sometimes grown in southern Italy, has thick, celery-like leaf stems.

Each leaf has a peculiar pair of fused, sheathing stipules known as an ochrea ( plural: ochreae ).

A definition which includes no instances is called a " primitive " ( or a " leaf ", or other names ); whereas a definition which includes instances is " hierarchical ".

However, if the electromagnetic radiation hitting the metal cap does not have a high enough frequency ( its frequency is below the threshold value for the cap ), then the leaf will never discharge, no matter how long one shines the low-frequency light at the cap.

These constraints enforce a critical property of red – black trees: that the path from the root to the furthest leaf is no more than twice as long as the path from the root to the nearest leaf.

Addiction or other deleterious effects from the consumption of the leaf in its natural form have not been documented in over a 5, 000 year time span, thus leading to the logical conclusion that coca left in its natural form causes no addictive properties at all.

Morales asserts that " la coca no es cocaína "— the coca leaf is not cocaine.

Outside of South America, most countries ' laws make no distinction between the coca leaf and any other substance containing cocaine, so the possession of coca leaf is prohibited.

In his view, it was the problem of the U. S. to deal with their own domestic problem of drug abuse, and that they had no right trying to eliminate coca, a legitimate product with many uses and a rich role to play in Andean culture.

Leaf gaps are small areas above the node of some leaves where there is no vascular tissue, as it has all been diverted to the leaf.

Some genera of ferns display complex leaves which are attached to the pseudostele by an outgrowth of the vascular bundle, leaving no leaf gap.

If a particular type of leaf is toxic to the fungus, the colony will no longer collect it.

The main advantage of such gear is that no other shock-absorbing device is needed ; the deflecting leaf provides the shock absorption.
