라이브 코딩테스트 2

다시 만들어 보자 

369게임의 조건은 이거 였나보다

/**
 * 1) 게임횟수만큼 순회 (100회)
 * 2) 초기 시작 숫자 : 1
 * 3) 현재 숫자 do369메서드 인자로 사용
 * 4) do369 - 숫자를 문자열로 변경
 * 5) do369 - 문자열에서 3, 6, 9 라는 숫자를 갖는지 체크
 * 6) ㄴ 있으면 clap 반환, 없으면 숫자 문자형태로 반환
 * 7) 현재 숫자를 말할 사용자 선택
 * 8) (현재 숫자-1 % 4) => players 인덱스
 * 9) do369의 결과와 인덱스에 해당하는 players를 sout로 출력
 */

 

대충 작성해 보면

public class TSNGameTestTwoMain {
    public static void main(String[] args) {
        int n = 100;
        String[] users = {"일출", "이토", "영삼", "사준"};
        for (int i = 1; i <= n; i++) {
            int index = (i -1) % 4;
            System.out.println(users[index] +" : "+ do369(i));
        }
    }

    private static String do369(int i) {
        String number = String.valueOf(i);
        char[] chars = number.toCharArray();
        int clapCount = 0;
        for (char c : chars) {
            if (c == '3' || c == '6' || c == '9') {
                clapCount++;
            }
        }

        if(clapCount > 0 ){
            return "clap";
        } else {
            return number;
        }
    }
}

결과

 

대충 이렇게 찍히는데 일단 369는 만든거 같고

1단계 : 주어진 요구사항에 맞게 369 게임

구현2단계 : 오답률에 따른 게임 종료 및 사용자 등 몇 가지 심화 기능과 클래스

추가3단계 : 지역별 다른 규칙의 369 게임을 위해 추상화 및 다형성

적용4단계 : 다양한 지역 동시 게임 진행을 위한 동시성 적용
