Astudent needs to take a certain number of courses to graduate, and these courses have prerequisites that must be followed. assume that all courses are offered every semester and that the student can take an unlimited number of courses per semester. given a list of courses and their prerequisites, write an algorithm in pseudocode to computer a schedule that requires the minimum number of semesters. give clear explanations on how the problems can be solved, including:
1. how to build the graph model of the problem: what are the vertices and what are the edges representing?
2. describe the procedure or the algorithm used to find the answer
