with type graph = t and type vertex = vertex
Mark on vertices.
Marks can be used if you want to store some information on vertices:
it is more efficient to use marks than an external table.
Type of graphs.
Type of graph vertices.
val clear :
graph -> unit
clear g sets all the marks to 0 for all the vertices of
val get :
vertex -> int
Mark value (in O(1)).
val set :
vertex -> int -> unit
Set the mark of the given vertex.
