There are a total of n courses you have to take, labeled from0Ton - 1.
Some courses may have prerequisites, for example to take course 0 you have to first take course 1, which is expressed as a pair:[0,1]
Given the total number of courses and a list of prerequisite pairs, is it possible for you to finish all courses?
For example:

1 Course Selection QuestionsLeetcode has such a problem: There is a code 0,1,2......n-1 of the N-gate course. Some of these courses require additional courses as prerequisites. Use a pair to represent these conditions: [1,0],[1,2], indicating that if you want to choose course 1, you must first take course 0 and course 2. Ask if it is possible to take these n courses all over again.The problem seems rather complicated. The difficulty is that a course m
