A sum divisor cordial labeling of a graph G with vertex set V (G) is a bijection f from V(G) to {1,2,3,,|V(G)|} such that an edge e = u v is assigned the label 1 if 2/[f(u) + f(v)] and 0 otherwise, then the number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. A graph which admits sum divisor cordial labeling is called a sum divisor cordial graph. In this research article we prove that the graphs obtained by switching ...
