+랜덤 숫자 생성
+
+- 범위는 1~9
+- 3개의 숫자를 받음
+- 중복되는 숫자가 있으면 안됨
+- camp.nextstep.edu.missionutils.Randoms을 통해 생성
+
+사용자 입력
+
+- 1~9사이의 숫자
+- 3개를 입력받음
+- 예외 처리 ( IllegalArgumentException 발생 후 종료 )
+    - 3개가 아닌 경우
+    - 중복되는 숫자가 있을 경우
+    - 1~9가 아닐 경우
+
+입력받은 수와 랜덤 수 비교
+
+- 스트라이크 : 같은 자리 && 같은 수
+- 볼 : 다른 자리 && 같은 수
+- 낫싱 : 다른 자리 && 다른 수
+
+결과 출력
+
+- 볼, 스트라이크 횟수 차례로 출력
+- 3스트라이크가 아닌 경우 다시 사용자 입력으로 돌아가기
+- 3 스트라이크면 종료 입력으로 이동
+
+종료 입력
+
+- ‘1’ 입력될 경우 재시작 ( 랜덤 숫자 단계로 다시 돌아감(= 재시작) )
+- ‘2’ 입력될 경우 게임 종료
+- ‘1’ or ‘2’ 가 아닌 숫자 입력될 경우 IllegalArgumentException 발생 후 종료
