What are the differences between segment trees, interval trees, binary indexed trees and range trees
...count per index can be increased in O(logn) time
Higher dimensions (d>1):
Segment tree - O(n(logn)^d) preprocessing time, O(k+(logn)^d) query time, O(n(logn)^(d-1)) space
Interval tree - O(n logn) preprocessing time, O(k+(logn)^d) query time, O(n logn) space
