The following solution will pass with numCourses = 7 and prerequisites = [[1,0],[0,3],[0,2],[3,2],[2,5],[4,5],[5,6],[2,4]] but it fails on leetcode

class Solution:
    def canFinish(self, numCourses: int, prerequisites: List[List[int]]) -> bool:
        courses = defaultdict(set)
        for c, p in prerequisites:
            courses[c].add(p)

        def canPass(course: int, visited: Set[int]) -> bool:
            if course not in courses:
                return True
            visited.add(course)
            for prerequisite in courses[course]:
                if prerequisite in visited:
                    return False
                if not canPass(prerequisite, visited):
                    return False
            del courses[course]
            return True

        for course in range(numCourses):
            visited = set()
            if not canPass(course, visited):
                return False
        return True
