Range Searching
... be done in O(log n) time. • Basic idea: Range tree first finds the set of points lying in [xlo, xhi] as union of O(log n) canonical sets. • Next, each canonical set is searched using the y-tree for range [ylo, yhi]. We locate ylo; then read off points until yhi reached. • Since each set is searched ...

... The root of left (right) subtree of a node is called a left (right) child of the node. A node without children is called a leaf. A special type of binary tree called a binary search tree is often useful. A binary search tree (with no duplicate elements) has the property that for every node in the tr ...
