문자열 뒤집기

• Java

  • for 문

    class Solution {
      public String solution(String my_string) {
          String answer = "";
          for(int i = my_string.length()-1; i >= 0; i--){
              answer += my_string.charAt(i);
          }
          return answer;
      }
    }

  • StringBuffer

    class Solution {
        public String solution(String my_string) {
            StringBuffer sb = new StringBuffer(my_string);
            String answer = sb.reverse().toString();
            return answer;
        }
    }

• Python

  • for 문

    def solution(my_string):
        answer = ''
        for i in my_string:
            answer = i + answer
        return answer

  • reversed()

    def solution(my_string):
        return ''.join(reversed(my_string))

  • slice [start:stop:step]

    def solution(my_string):
        answer = my_string[::-1]
        return answer
