求一个正整数 倒转后加上1024的结果.比如 12345倒转后是54321,加上1024，结果是55345.

public static void main(String[] args) {
    
        System.out.println("请输入一个正整数");
        Scanner input = new Scanner(System.in);
        int sum = 0;
        for (int num = input.nextInt(); num > 0; num /= 10) {
            sum = sum * 10 + (num % 10);
        }
        System.out.println(sum + 1024);
    }
