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.

WebFeb 9, 2024 · 2.3 Cartesian Tree Subsequence Matching. Let T be a text string of length n and P be a pattern string of length m≤n . 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.

WebJul 6, 2024 · We use a stack to dynamicly keep track of all the left bars that are shorter than a certain bar. In other words, if we iterate from the first bar to bar [i], when we just arrive at the bar [i] and haven't updated the stack, the stack should store all the bars that are no higher than bar [i-1], including bar [i-1] itself. WebApr 15, 2015 · 3. In the windowing query, given a set of line segments and an axis-aligned rectangle, we have to find the intersections of the line segments with the rectangle.
