Doubt in a concept

#1

Sir, if it is an undirected edge, then is it considered as one single edge or is it counted as 2 edges?

#2

hello @vageesha

theoretically it is one single edge but while implementing we push two directional edges (a->b ,b->a) to get an undirected edge

#3

sir, then the maximum number of edges in case of a connected graph should be 2*nc2 and not nc2?

#4

@vageesha

its nc2 … every node is connected to every other node .
see only while implementation we push two eges a->b b->a to indicate bidirectional nature of edge.
