u is reachable from v.v is reachable from u.There is no relationship between u and v.They have the same in-degree.
Question
u is reachable from v. v is reachable from u. There is no relationship between u and v. They have the same in-degree.
Solution
The statement seems to be a bit contradictory. If "u is reachable from v" and "v is reachable from u", it implies that there is a relationship between u and v, specifically, a bidirectional relationship. This contradicts the statement "There is no relationship between u and v".
The statement "They have the same in-degree" means that the same number of edges are directed towards both u and v in a directed graph.
So, to make sense of this, we could interpret it as: In a directed graph, there are paths from u to v and from v to u, but there is no direct edge between u and v. Both u and v have the same number of incoming edges.
