## Counting Shortcuts solution codeforces – Given an undirected connected graph with nn vertices and mm edges. The graph contains no loops (edges from a vertex to itself) and multiple edges (i.e. no more than one edge between each pair of vertices). The vertices of the graph are numbered from 11 to nn.
