Module `Segmenttree`Source

This module is a very simple implementation of "segment trees".

A segment tree of type 'a t represents a mapping from a union of disjoint segments to some values of type 'a.

Sourcetype 'a t

A mapping from a union of disjoint segments to some values of type 'a.

Sourceval make : ((int * int) * 'a) list -> 'a t

make [(i1, j1), v1; (i2, j2), v2; ...] creates a mapping that associates to every integer x the value v1 if i1 <= x <= j1, v2 if i2 <= x <= j2, and so one. Precondition: the segments must be sorted.

Sourceval lookup : int -> 'a t -> 'a

lookup k t looks for an image for key k in the interval tree t. Raise Not_found if it fails.
