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.
