Fixless

And oft upon yon craggy mount, Where threat'ning cliffs hang high, Have I observ'd him stop to count With fixless stare the sky.

Two essential elements to public acceptance of the meters are : (1) the use of "fixless" traffic tags, issued in quadruplicate and excused only by the municipal court; and (2) maintenance of the meters in first class operating condition at all times.

The fixless algorithm increments by integer parameter n both the less fields of those ancestors or (pointer parameter) node p which have p as a left-descendant, and the size of the tree. Integer n may be negative, as after a deletion.
