I think at one stop which is the start stop of another route,we can print that route start with the common stop.But this is not the solution with the minimum stops.I got wa on test 1.I'm confused.Can anybody help me?

My code:

I have WA#1 too. But I think that my program must work correctly. I always output the route with a number of stops equal to the m_1+m_2+...+m_n (m_k is a number of stops in k_th route). So I have a question: for input
2
4 1 2 3 4 1
4 1 2 3 4 1
should I output
4 1 2 3 4 1
or the output
8 1 2 3 4 1 2 3 4 1
is also OK?

I haven't looked November Rain's program yet, but I suspect he to have the same algorithm that I have.

Test is incorrect
"None of the routes shared the same section of road"
