Range query tree

Tree-based data structure

In computer science, a Range Query Tree, or RQT, is a term for referring to a data structure that is used for performing range queries and updates on an underlying array, which is treated as the leaves of the tree. RQTs are, in principle, complete binary trees with a static structure, where each node stores the result of applying a fixed binary operation to a range of the tree's leaves.
