can someone give me the test case #5?

 i got wa on that case.
 i'm using method of giving points to each person, so that every child has more points than his father. i'm doing that with bfs:

if points[child] <= points[parent]
  points[child] = points[parent] + 1;
bfs (child);

 i think method is right.

you can find other tests here: http://timustests.lx.ro
