Suppose you are working on creating an automatic course planner for WWU students. A student can get a total ofn courses, labeled from 0 to n - 1. Some courses may have prerequisites, for example, to take course 241 you have to first take course 145, which is expressed as a pair: [241, 145] (the current course, the prerequisite of the current course). Given the total number of courses and a list of prerequisite pairs, you need to: Determine if it is possible to finish taking the n courses. If not, print “It is impossible to take all the given courses." If yes, print “It is possible to take all the given courses.", and move to the next step. Generate one schedule of the given courses (prerequisites have to be scheduled first for any courses). Print the courses out with white spaces as separators. There might be multiple valid schedules, but you only need to generate one of them. Еxample 1: 4, [[1,0], [2,e], [3,1]] Output: It is possible to take all the given courses. A possible schedule is 0, 1, 2, 3. Explanation: There are a total of 4 courses to take. To take courses 1 or 2 you should take course 0 first. To take course 3, you should take 1 first.
