A reverse edge magic total labeling of a graph ???? is a one-to-one map ????∶????(????)∪????(????)→{1,2,…,|????(????)∪????(????)|}=[1,|????(????)∪????(????)|] with the property that there is an integer constant ???? such that {????(????????)−(????(????)+????(????))????????∈????(????)⁄}=????. If (????(????))=[1,|????(????)|] then the reverse edge magic labeling is called reverse super edge-magic labeling. In this paper we will formulate the reverse edge magic labeling of two subclasses of trees.
