Order statistic tree
text:
In computer science, an order statistic tree is a variant of the binary search tree that supports two additional operations beyond insertion, lookup and deletion:
- Select(i) – find the i-th smallest element stored in the tree
- Rank(x) – find the rank of element x in the tree, i.e. its index in the sorted list of elements of the tree Both operations can be performed in O(log n) worst case time when a self-balancing tree is used as the base data structure.
