将输入进来的字符串逆序加到stringbuilder中，然后再tostring输出即可
public class Main {
public static void main(String[] args) {
//逆序输出
Scanner sc = new Scanner(System.in);
String s = sc.next();
StringBuilder sb = new StringBuilder();
for (int i = s.length()-1; i >=0 ; i--) {
sb.append(s.charAt(i));
}
System.out.println(sb.toString());
}
}
