999E wrong ans on test case 31

Правка en3, от Doritos4, 2018-08-21 08:43:59

I'm getting wa31 for this problem ( my submission ).

First, I find all vertices that can be reached from the capital. Then, I look at all vertices which have indegree equal to 0. These vertices must have an edge directly connecting them to the capital and can obviously be visited in any order. Now, if unvisited vertices remain, they must form a cycle. I visit these vertices next ( again, in any order).

Please help
