배열 회전시키기

 

 

코드

class Solution {
    public int[] solution(int[] numbers, String direction) {
        int[] answer = new int[numbers.length];

        if (direction.equals("right")) {
            answer[0] = numbers[numbers.length -1];
            for (int i = 0; i < numbers.length - 1; i++) {
                answer[i + 1] = numbers[i];
            }
        } else {
            answer[answer.length - 1] = numbers[0];
            for (int i = 1; i < numbers.length; i++) {
                answer[i - 1] = numbers[i];
            }
        }

        return answer;
    }
}
