  Binary search tree - Wikipedia, the free encyclopedia
Everything in the left subtree of a node is strictly less than the value of the node, but everything in the right subtree is either greater than or equal to the value of the node.
In other words, we examine the root and recursively insert the new node to the left subtree if the new value is less than or equal to the root, or the right subtree if the new value is greater than the root.
We replace the value of N with either its in-order successor (the left-most child of the right subtree) or the in-order predecessor (the right-most child of the left subtree).

 Cool Solutions: Subtree Searches in eDirectory 8.8
So, a client searching a subtree with a small number of entries below it is comparable in performance to a client searching a subtree with a large number of entries.
Until all the objects in the subtree are updated with the new Ancestor ID information, subtree search operations will behave the way they did prior to 8.8.
Subtree operations are vastly faster in eDirectory 8.8, if the filter criteria of the search matches many objects in the database (e.g.

 LWN: Shared subtrees
The merging of the filesystems in user space patch, and some of the permissions issues associated with it, has increased the desire to be able to run users in their own filesystem namespaces.
Al Viro has worked with a few iterations of the shared subtrees patch, with the result that it is now considered to be ready for the mainline.
The shared subtrees patch is a big step forward: it is a fundamental change to the virtual filesystem layer which greatly increases the flexibility in how namespaces can be populated and presented to users.

 Tree traversal - Wikipedia, the free encyclopedia
In both cases, values in the left subtree are printed before values in the right subtree.
To see why this is the case, note that if n is a node in a binary search tree, then everything in n's left subtree is less than n, and everything in n's right subtree is greater than or equal to n.
Thus, if we visit the left subtree in order, using a recursive call, and then visit n, and then visit the right subtree in order, we have visited the entire subtree rooted at n in order.

A subtree specification is always used within a context or scope which implicitly determines the bounds of the subtree.
Where a subtree specification does not identify a contiguous subset of the entries within a single subtree the collection is termed a subtree refinement.
The subtree or subtree refinement contains all the entries within scope that are not excluded by any of the components of the subtree specification.

 RRFW XML Configuration Guide
All parameters are inherited by the subtrees and leafs from their parents, and can be overridden on lower levels.
Each subtree or a leaf is identified by a path, the symbolic notation similar to filesystem paths.
In this case, any subtree is identified by a path ending with slash, while leaf paths always end with a word symbol.

 Topic #9: Binary search trees
If the value of k is smaller than that of x, then it should be in the left subtree of x; if the value of k is larger than that of x, then it should be in the right subtree of x; otherwise k is not an element of the binary search tree.
Suppose the smallest element in the right subtree of p is the one chosen (note that always choosing that element will lead to an unbalanced tree, since the repeated use of the algorithm will move nodes "to the left").
Note that one of the advantages of using this operation is that the only part of the tree to be affected by the operation is the subtree of p (the shaded triangle), which consists of all the nodes inserted after p, falling between the two ropes of p.

 Lecture 9 - Deleting a Node From a Binary Search Tree   (Site not responding. Last check: 2007-11-01)
This always works, whether the one subtree is on the left or on the right.
If X is coming from the left subtree, (1) says that there is a unique choice for X - we must choose X to be the largest value in the left subtree.
So our general algorithm is: to delete N, if it has two subtrees, replace the value in N with the largest value in its left subtree and then delete the node with the largest value from its left subtree.

 How the Registry Is Architected
Of the five subtrees, only two — HKLM and HKU — are "real." What I mean by "real" is that they are the only two subtrees backed by files, the only two that exist regardless of whether someone is logged on to the machine.
This subtree is normally accessible only via API call, and it provides applications with access to the same data that Win2K’s Performance Monitor tool uses to view and log performance data.
The fifth subtree, HKCU, is actually the "Settings" portion of a logged-on NT or Win2K user profile and an alias of a special subkey that is loaded into the HKEY_USERS subtree at user logon — based on the user’s Win2K Security Identifier (SID).

 InfoVis 2003 Contest - TreeJuxtaposer Entry
The largest number of nodes in a subtree is not quantitatively visible in TreeJuxtaposer, but the density of tree edges in a region corresponds to a larger number of nodes in a subtree and can be used to judge the relative size of a subtree.
If a large subtree, for example rodentia, is highlighted in A with blue, the nodes in B that are highlighted are all in the rodentia subtree.
Furthermore, if the rodentia subtree in B is now highlighted with green, there are no nodes highlighted in either classification tree that are outside of the rodentia group.

 AVL Trees: Tutorial and C++ Implementation
The criteria that is used to determine the "level" of "balanced-ness" is the difference between the heights of subtrees of a root in the tree.
It is true that the structure of one of the subtrees may have changed due to an insertion and/or rotation, but since the height of the subtree did not change, neither did the height of the current level.
The height of the current level may decrease for two reasons: either a rotation occurred to decrease the height of a subtree (and hence the current level), or a subtree shortened in height resulting in a now balanced current level (subtree was "trimmed down" to the same size as the other).

Such a (subtree, list) tuple defines a set of objects and their values to be collected as accounting data for a connection.
The subtree specifies a single OBJECT IDENTIFIER value such that each object in the set is named by the subtree value appended with a single additional sub-identifier.
Each data item is represented by an integer which when appended (as as additional sub-identifier) to the OBJECT IDENTIFIER value of the subtree identified by the tuple, is the name of an object defining that data item (its description and its syntax).

 Binary Search Tree
This is because when the tree is balanced, that is the difference between the heights of the left and right subtrees is O(1), its height is O(logN), where N is the number of elements in the tree.
When the element to be removed is not at a leaf node, we can replace it with the largest element of the left subtree (if it's not empty) or the smallest element of the right subtree (if it's not empty).
In preparation, we write two visitors: one to find the subtree containing the largest element at the root, the other to find the subtree containing the smallest element at the root.

Note that each node of a tree can be considered to be the root of a subtree consisting of that node and all its descendants.
To be precise, starting at any given node, the data in any nodes of its left subtree must all be less than the item in the given node, and the data in any nodes of its right subtree must be greater than or equal to the data in the given node.
Notice that it is handed a pointer to a node of the binary search tree and then follows a postorder traversal pattern to visit all of the nodes of the subtree rooted at the given node.

 Java Programming: Section 11.4
In a preorder traversal, the root node of the tree is processed first, then the left subtree is traversed, then the right subtree.
The definition of an inorder traversal guarantees that all the items in the left subtree of "judy" are printed before "judy", and all the items in the right subtree of "judy" are printed after "judy".
But the binary sort tree property guarantees that the items in the left subtree of "judy" are precisely those that precede "judy" in alphabetical order, and all the items in the right subtree follow "judy" in alphabetical order.

th element in the tree: you can look at the root node and work out which subtree the element is in (or whether it's one of the elements in the root node), and then recurse down to the next node adjusting your count.
When you split a node into two, you must add up the subtree counts in each half to determine what to put in the subtree counts of the new links to that node.
When you add or remove a subtree in the middle of a node, you need to adjust the count in the link to that node.

 2.5. View Subtree
A view subtree is the set of all MIB object instances which have a common ASN.1 OBJECT IDENTIFIER prefix to their names.
A view subtree is identified by the OBJECT IDENTIFIER value which is the longest OBJECT IDENTIFIER prefix common to all (potential) MIB object instances in that subtree.
When the OBJECT IDENTIFIER prefix identifying a view subtree is longer than the OBJECT IDENTIFIER of an object type defined according to the SMI [3], then the use of such a view subtree for access control has granularity at the object instance level.

The rotator node is the root of the pivot's taller subtree.
On the other hand, if the rotator is the left child the inside subtree is its right subtree and the outside subtree is its left subtree.
It is taller than the outside subtree (which is empty), so we rotate `3' up, and `1' down (to the outside) etc.
