오! swift에서는 null이 nil인가 보네요. 신기했어요.
근데 사실 저 이 문제를 제대로 이해하진 못했는데, fast와 slow라는 네이밍을 다들 사용하고 계시더라구요. 혹시 그 이유를 아시나요?

맞아요 swift에는 null을 nil로 써요.
플루이드의 순환 알고리즘(일명 토끼와 거북이 알고리즘)으로 풀었기 때문에. 2칸 이동하는 토끼 = fast, 1칸 이동하는 거북이 = slow라는 네이밍을 쓰고 있어요.

나머지 문제들은 난이도가 올라가는 점과 시간이 없는 부분 때문에 확인을 못했는데 생각보다 어려운 문제는 아니었나 싶기도 하네요. 한 번도 접해본 적 없는 언어로 된 코드는 거의 처음 보는데 의도가 명확하게 보였습니다!
