Dynamic cartesian tree
A Cartesian tree may be constructed in linear time from its input sequence. One method is to simply process the sequence values in left-to-right order, maintaining the Cartesian tree of the nodes processed so far, in a structure that allows both upwards and downwards traversal of the tree. To process each … See more In computer science, a Cartesian tree is a binary tree derived from a sequence of numbers. The smallest number in the sequence is at the root of the tree; its left and right subtrees are constructed recursively from the … See more Cartesian trees were introduced and named by Vuillemin (1980). The name is derived from the Cartesian coordinate system for the … See more 1. ^ In some references, the ordering is reversed, so the parent of any node always has a larger value and the root node holds the maximum value. 2. ^ Vuillemin (1980). See more The Cartesian tree for a sequence of numbers is defined by the following properties: 1. The … See more Range searching and lowest common ancestors Cartesian trees may be used as part of an efficient data structure for range minimum queries, a range searching problem involving queries that ask for the minimum value in a … See more WebSep 5, 2012 · We show that a Cartesian tree of a tree can be constructed in linear time plus the time required to sort the edge-weights. It can then be used to answer bottleneck edge queries in constant time for trees and undirected graphs.

WebOct 3, 2014 · We show that bottom-up traversals of the multiway Cartesian tree on the interleaved suffix array and longest common prefix array of a string can be used to answer certain string queries. By adding downward pointers in the tree (e.g. using a hash table), we can also generate suffix trees from suffix arrays on arbitrary alphabets in the same bounds.

We say that a pattern P matches text T, denoted by P ⊑T, if there exists a subscript sequence I =(i1,…,im)∈I nm of T such that CT (T I)=CT (P) holds. Then, we refer to the subscript sequence I as a trace. WebFeb 26, 2012 · Dynamic tree in C++. Ask Question Asked 11 years, 1 month ago. Modified 11 years, 1 month ago.
