[프로그래머스/알고리즘] 수박수박수박수 (자바/Java)

문제 설명

길이가 n이고, "수박수박수박수...."와 같은 패턴을 유지하는 문자열을 리턴하는 함수, solution을 완성하세요. 예를들어 n이 4이면 "수박수박"을 리턴하고 3이라면 "수박수"를 리턴하면 됩니다.

 

제한 조건

• n은 길이 10,000이하인 자연수입니다.

 

 

 

Step1. 문제분석 

반복문을 돌아서 i의 값이 첫번째, 두번째 이렇게 순서대로 하려면 2를 나눠서 나머지 값이 0일때, 1일때 2가지 조건으로

'수', '박' 이런 순서대로 들어가면 된다.

 

Step2. 문제풀이 코드

class Solution {
    public String solution(int n) {
    String answer = "";
        for(int i = 0; i < n; i++){
            if(i % 2 == 0){
                answer += "수";
            }if(i % 2 == 1){
                answer += "박";
            }
            
        }
        return answer;
    }
}

생각보다 너무 간단했다.

보고 빵 터졌다. 이렇게 한 사람이 진짜 있을 줄이야 ,,, 그냥 뭐야 이게 ㅋㅋㅋ 하면서 웃었는데

성능이 좋다는 거에 놀랐다. 정말 정답은 없는 거 같다

class Solution {
    String text =

바로 어제 substring에 대해 공부를 했는데 그새 잊었다.

금붕어 인가 보다.

이 또한 좋은 방법이라고 생각했다.

public class WaterMelon {
    public String watermelon(int n){

        return new String(new char [n/2+1]).replace("\0", "수박").substring(0,n);
    }
}

 

삼항연산자

다음에는 꼭 삼항 연산자로 풀어 봐야지

public class WaterMelon {
    public String watermelon(int n){
    String result = "";
    for (int i = 0; i < n; i++)
      result += i % 2 == 0 ? "수" : "박";
        return result;
    }
}
