  2. Tree traversal - Wikipedia

    en.wikipedia.org/wiki/Tree_traversal

    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.

    en.wikipedia.org/wiki/Geometry_of_binary_search...

    In the geometric view of the online binary search tree problem, an access sequence,..., (sequence of searches performed on a binary search tree (BST) with a key set ,,...,) is mapped to the set of points (,), where the X-axis represents the key space and the Y-axis represents time; to which a set of touched nodes is added.

    en.wikipedia.org/wiki/Binary_search_tree

    Fig. 1: A binary search tree of size 9 and depth 3, with 8 at the root. In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree.

  5. Trie - Wikipedia

    en.wikipedia.org/wiki/Trie

    The trie occupies less space in comparison with a BST in the case of a large number of short strings, since nodes share common initial string subsequences and store the keys implicitly. [ 12 ] : 358 The terminal node of the tree contains a non-null value, and it is a search hit if the associated value is found in the trie, and search miss if it ...

  9. Binary tree - Wikipedia

    en.wikipedia.org/wiki/Binary_tree

    In pre-order, we always visit the current node; next, we recursively traverse the current node's left subtree, and then we recursively traverse the current node's right subtree. The pre-order traversal is a topologically sorted one, because a parent node is processed before any of its child nodes is done.
