+# Leets 미션 1주차
+
+##  👥 미션 - 오늘의 짝꿍은?
+
+### ✅ 핵심 기능
+
+**목표**
+
+나의 짝꿍을 정해줄 랜덤 짝꿍 매칭 프로그램을 작성
+
+### ✅ 1주차 미션 목표
+
+#### 과제를 통해 생각해보기
+- 어떻게 하면 코드를 효율적으로 짤 수 있는지
+- 어떻게 하면 유지 보수가 쉬운 코드가 될 수 있는지
+- 객체지향 프로그래밍이 목표하는 바가 무엇이고 이를 어떻게 코드로 구현할 수 있는지
+
+### ✅ 구현할 기능 목록
+**[ Domain ]**
+-
+
+- [x]  **Member**
+
+- 참가자의 데이터 구조와 관련 로직을 담당
+- 문자열로된 멤버들을 리스트로 분리하고, 총 멤버수를 반환합니다.
+
+**[ Service ]**
+-
+
+- [x]  **GroupService**
+- 참가자들을 그룹화하는 로직을 담당
+- 랜덤 짝꿍을 추첨합니다.
+
+**[ View ]**
+-
+
+- [x]  **InputView**
+
+- 멤버 이름을 입력받음 (,로 구분)
+- 최대 짝 수를 입력받음
+- 다시 구성할지 말지 입력받음(y,n)
+
+- [x]  **OutputView**
+- 짝 추천 결과를 보여줌(default, y)
+- 인사 메세지를 보여줌(n)
+
+**[ Controller ]**
+-
+
+- [x]  **MatchingController**
+짝궁 추천 요청을 처리하는 로직을 구현
+
+### ✅ 예외 처리 - exception
+
+********공통********
+
+- [x]  예외 상황 시 에러 문구를 출력. 단, 에러 문구는 "[ERROR]"로 시작
+
+---
+
+**이름 입력**
+
+- [x] 이름이 한글이 아니면 예외처리
+
+---
+
+**최대 짝수 입력**
+
+- [x] 최대 짝 수가 이름의 갯수보다 크면 예외처리
+---
+
+**retry 입력**
+- [x] y와 n 이외의 숫자면 예외처리
+
+
