Problem J. Feedback Meetings
*****
Se um funcionário não tem nada para dizer, i.e, vértice isolado. Ele precisa estar em alguma reunião?
Se um funcionário não tem algo para dizer para ninguém e ninguém tem algo a dizer para ele, então ele não precisa fazer uma reunião com o RH.

If an employee does not have anything to say to no one and no one has anything to say to him, then this employee does not need to schedule a meeting with the HR.
