기본적으로 변수명과 클래스명은 명사로, 함수명은 동사로 지어주어야 합니다!
코틀린 컨벤션 가이드를 참고하시면 좋을 것 같아요.

그리고 자동 정렬을 습관화하시면, 더 쉽게 코틀린 컨벤션을 지킬 수 있답니다!
코드를 읽어보니 :
띄어쓰기가 잘 안 되어 있는 것 같더라고요.
자동 정렬 단축키
윈도우: ctrl+shift+alt+L
맥: command+option+L

디버그용으로 작성하신 출력문인 것 같은데, 커밋 전에는 꼭 지워주세요!

str
을 선언한 이유가 있으신가요? 분기문에서는 str
의 값을 변경하는 작업이 보이지 않아서 여쭙니다!
그리고 코틀린 컨벤션에서는 다중 if
문보다는 when
을 권장하기 때문에 when
사용 고려해보시면 좋을 것 같습니다!

승연님 말씀대로 val str = when() 해서 분기하면 더 좋을 것 같아요!

return 값으로 돌려줘야해서 구현에 급급해서 그렇게 짰었네요..! 다음번엔 when() 사용 해봐야겠습니다 !

이거 귀엽네요 areUReady ㅎㅎ
그래두 승연님 말씀대로 바꾸시면 더 좋을 것 같아요!

저도 지영님께 배웠는데, forEachIndexed 사용해도 좋을 것 같아요!

다음번엔 forEachIndexed 활용해보겠습니다 👍 감사합니다!

상수화 시켜주셨는데 enum class
를 활용해보셔도 좋을 것 같습니다!

enum class 생각도 못했네요,,..! 좋은 의견 감사합니다 !

if
문이 3개 이상 사용된다면 when
사용을 고려해보시는건 어떨까요?

이 조건문은 user[i] 가 computer 에 속하지 않는다면 -> continue
인 것 같아요.
그렇다면 if (user[i] in computer)
에 대한 처리도 필요할 것 같아보입니다!
