You are given a connected undirected graph G, consisting of N vertices and M edges. The vertices of G are indexed with integers 1, 2, 3, ..., N, the edges of G are indexed with integers 1, 2, 3, ..., M. Each edge of G has a capacity - a positive integer parameter. Each pair of the vertices is connected by at most one edge. No edge connects a vertex with itself. Let's call a sequence of vertices A
