[프로그래머스/C++] 배열 회전시키기

문제

정수가 담긴 배열 numbers와 문자열 direction가 매개변수로 주어집니다. 배열 numbers의 원소를 direction방향으로 한 칸씩 회전시킨 배열을 return하도록 solution 함수를 완성해주세요.

 

솔루션

#include <string>
#include <vector>

using namespace std;

vector<int> solution(vector<int> numbers, string direction) {
    vector<int> answer;
    if(direction == "right"){
        answer.push_back(numbers[numbers.size()-1]);
        for(int i = 0; i < numbers.size()-1;i++){
            answer.push_back(numbers[i]);
        }
    }
    else{
        for(int i = 1; i < numbers.size();i++){
            answer.push_back(numbers[i]);
        }
        answer.push_back(numbers[0]);
    }
    return answer;
}
