Tree_order_statistics_node_update
WebA tree and its update policy. node_update (an instantiation of Node_Update) must define metadata_type as the type of metadata it requires. For order statistics, e.g., metadata_type might be size_t. The tree defines within each node a metadata_type object. node_update must also define the following method for restoring node invariants: WebNAME __gnu_pbds::tree_order_statistics_node_update< Node_CItr, Node_Itr, Cmp_Fn, _Alloc > - Functor updating ranks of entrees.

WebI know that your purpose is to implement the RB-tree. But if you just take a step back, you can see that the operations needed for this problem are: building the tree, finding number (base on rank/position), and deletion. There is no insertion, therefore there is no need for self-balancing once the tree is built.
WebAdds order statistics to each node and the tree itself: report a value position in sorted list. report the count of values above and below a certain value. report percentile, median, ... recurse toward the tree root to update the counters. and may: trigger rebalancing if a node is added or removed. heather eckleyWebsplay_tree_tag :splay 树. ov_tree_tag :有序向量树,只是一个由 vector 实现的有序结构,类似于排序的 vector 来实现平衡树,性能取决于数据想不想卡你.

The 0th order statistic is the minimum value. The 1st order statistic is the second-smallest value. The (n – 1)st order statistic is the maximum value.
