You need to complete numCourses courses labeled from 0 to numCourses - 1.

Each pair [course, prerequisite] means that prerequisite must be completed before course.

Return true if it is possible to complete every course. Otherwise, return false.

canFinishCourses(numCourses: int, prerequisites: int[][]) → boolean

numCourses = 2prerequisites = [[1,0]]return = true

Take course 0 first, then course 1.

numCourses = 2prerequisites = [[1,0],[0,1]]return = false

Each course requires the other first, so the prerequisite graph contains a cycle.

numCourses = 4prerequisites = [[1,0],[2,1],[3,2]]return = true

The order 0, 1, 2, 3 completes every course.
