중복된 id 리스트가 나올 수 있는 경우가 있나요?

로직 상이나 stageParticipant가 중복되어 나올 수 없지만 혹시 모를 이유로 id를 추출할 때 중복되어버린다고 가정하여서 id가 중복이 될 수 없도록 set -> list로 변환하는 과정을 추가하였습니다 |

개요
랭킹 리스트를 반환하는 도중에 동알인물이 중복으로 반환되는 상황이 생겨 수정하였습니다.
본문
studentParticipants를 조회 후 studentIds를 추출하는 중에 중복된 id가 들어가는 상황이 생겨 .toSet().toList()를 사용하여 중복을 방지하였습니다.
