Sukhnandan has got an undirected graph consisting of n vertices and m edges. This graph doesn't contain any self-loops or multiple edges. Self-loop is an edge connecting a vertex to itself. Multiple edges are a pair of edges such that they connect the same pair of vertices. Since the graph is undirected, the pair of edges (1,2) and (2,1) is considered to be multiple edges. An isolated vertex of th
