#사다리게임
2+
3+
##1단계
4+
- 4X4 크기의 사다리를 출력한다.
5+
- 가로라인이 겹치지 않게 랜덤으로 줄을 긋는다.
6+
7+
##2단계
8+
-사다리 넓이와 높이를 입력받아, 그 크기의 사다리를 출력한다.
9+
10+
##3단계
11+
-0부터 인덱스 번호를 부여해 사다리 타고 난 후 결과를 출력하낟.
12+
13+
##4단계
14+
-사다리 게임에 참여하는 사람에 이름을 최대 5글자까지 부여할 수 있다. 사다리를 출력할 때 사람 이름도 같이 출력한다.
15+
사람 이름은 쉼표(,)를 기준으로 구분한다.
16+
-개인별 이름을 입력하면 개인별 결과를 출력하고, "all"을 입력하면 전체 참여자의 실행 결과를 출력한다.
17+
18+
##5단계
19+
-리팩토링
