Given a list of lectures v1,v2,...,vn. As usual, there is a dependency between the lectures. That is, some lectures require that one or more other lectures have already been attended. Participation in a lecture is only possible if its prerequisites are fulfilled. These dependencies are given as a list of pairs.     Specify an algorithm in pseudo code that determines the order in which the lectures can be attended for given lectures and their prerequisites.     Determine the running time of the algorithm and give a reason for the correctness of your algorithm.
