정답 

 

- 뒤집은 문자열과 원래 문자열이 동일하다면 회문으로 간주 

- StringBuilder는 reverse()라는 뒤집는 메소드 제공

import java.util.Scanner;
 
class Solution
{
    public static void main(String args[]) throws Exception
    {   
        Scanner sc = new Scanner(System.in);
         
        int T = sc.nextInt();
         
        boolean check = false;
        for(int t=1; t<=T; t++)
        {
            String str = sc.next();
            int answer = 0;
             
            String reverseStr = new StringBuilder(str).reverse().toString();
             
            answer = (str.equals(reverseStr))?1:0;
 
            System.out.printf("#%d %d\n",t,answer);
        }
    }
}
