Add arcs b j -> a j+1 for j = 1, ..., m-1 and arcs b j -> a 1 for j = m, ..., n. The resulting graph is strongly connected because the a's and b's are strongly connected by the added arcs and the paths from a i to b i and, for every node x, there exist i, j such that there exists a path in the original graph from a i to ...
