Depending on the problem at hand, pre-order, post-order, and especially one of the number of subtrees − 1 in-order operations may be optional. Also, in practice more than one of pre-order, post-order, and in-order operations may be required. For example, when inserting into a ternary tree, a pre-order operation is performed by comparing items.
One problem with this algorithm is that, because of its recursion, it uses stack space proportional to the height of a tree. If the tree is fairly balanced, this amounts to O(log n) space for a tree containing n elements. In the worst case, when the tree takes the form of a chain, the height of the tree is n so the algorithm takes O(n) space. A ...
The motivation for inclusion of array was that it solves two problems of the C-style array: the lack of an STL-like interface, and an inability to be copied like any other object. It firstly appeared in C++ TR1 and later was incorporated into C++11.
The necessary distinction can be made by first partitioning the edges; i.e., defining the binary tree as triplet (V, E 1, E 2), where (V, E 1 ∪ E 2) is a rooted tree (equivalently arborescence) and E 1 ∩ E 2 is empty, and also requiring that for all j ∈ { 1, 2 }, every node has at most one E j child.

Sorting a set of unlabelled weights by weight using only a balance scale requires a comparison sort algorithm. A comparison sort is a type of sorting algorithm that only reads the list elements through a single abstract comparison operation (often a "less than or equal to" operator or a three-way comparison) that determines which of two elements should occur first in the final sorted list.
[5] [6] The problem is most often solved by inserting memory barrier instructions into the program. [6] [7] In order to fully utilize the bandwidth of different types of memory such as caches and memory banks, few compilers or CPU architectures ensure perfectly strong ordering.
In the other direction, to define a strict weak ordering < from a total preorder , set < whenever it is not the case that . [8] In any preorder there is a corresponding equivalence relation where two elements x {\displaystyle x} and y {\displaystyle y} are defined as equivalent if x ≲ y and y ≲ x . {\displaystyle x\lesssim y{\text{ and }}y ...
Each node of a ternary search tree stores a single character, an object (or a pointer to an object depending on implementation), and pointers to its three children conventionally named equal kid, lo kid and hi kid, which can also be referred respectively as middle (child), lower (child) and higher (child).
