[백준/JAVA]10988번 팰린드롬인지 확인하기

문제

https://www.acmicpc.net/problem/10988

주어진 문자열이 팰린드롬(앞뒤가 같은 문자열)인지 검사하는 문제였다.

문제 풀이

1. toCharArray()

import java.io.*;
public class Main {
    public static void main(String[] args) throws IOException{
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        char[] words=br.readLine().toCharArray();
        int result=1;
        
        for(int i=0;i<words.length/2;i++){
            if(words[i]!=words[words.length-i-1]){
                result=0;
                break;
            }
        }
        
        System.out.print(result);
    }
}

2. split()

import java.io.*;
public class Main {
    public static void main(String[] args) throws IOException{
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        String[] words=br.readLine().split("");
        int result=1; 

        for(int i=0;i<words.length/2;i++){
            if(!words[i].equals(words[words.length-i -1])){
                result=0; 
                break;
            }
        }

        System.out.print(result);
    }
}
