DynamicSegmentTree 最近尝试了一下动态开点线段树,英文直译就是Dynamic Open Point Segment Tree,太SB了。 就跟之前的主席树写法差不多。 主席树 动态开点线段树 实际上当普通线段树用就行了... 例题:洛谷P1908 逆序对 我们可以不离散化,使用动态开点,直接在1e9上开值域线段树。吸氧后堪堪A掉。 AC代码 例题:...
2-3 treeparallelunion-copy structureinsertiondeletionThe dynamic segment tree data structure is used to store a set of n line segments whose end points are in the range [―∞,∞]. Given k segments in sorted order and a segment tree storing n segments, we obtain the following results -...
So basically, we initially have the root only which stores the whole interval ([1;10^9] for example). Then the update/query goes exactly like in the normal segment tree but if we don't have a child of some node but we need it, we just create it and go on. I implementedHorrible ...
As an application of the union-copy structure, we give a dynamic version of the segment tree. Contrary to the classical semi-dynamic segment trees, the dynamic segment tree is not restricted to a fixed universe, from which the endpoints of the segments must be chosen. The tree allows for ...
