Task Description
Bounty: 课程表 (Course Schedule)
任务概览 (Task Overview)
你这个学期必须选修 numCourses 门课程,记为 0 到 numCourses - 1。在选修某些课程之前需要一些先修课程。例如,想要学习课程 0 ,你需要先完成课程 1 ,我们用一个匹配来表示:[0, 1]。
给定课程总量以及它们的先修关系列表 prerequisites,请你判断是否可能完成所有课程的学习?
目标 (Objectives)
- 实现函数
can_finish(num_courses: int, prerequisites: List[List[int]]) -> bool。 - 算法应高效处理大规模输入,建议使用拓扑排序(Topological Sort)或深度优先遍历(DFS)进行环路检测。
- 评估将侧重于算法的正确性和时间复杂度 $O(V + E)$。
