  public static void main(String[] args) {
    System.out.println(isPalindrome(123456));
    System.out.println(isPalindrome(1234321));
    
    System.out.println(isPalindrome(1010));
    System.out.println(isPalindrome(10101));
  }

  private static boolean isPalindrome(int num) {
    return num == reverseNumber(num);
  }
  
  private static int reverseNumber(int num) {
    int sum = 0;
    while (num > 0) {
      sum = (sum * 10(num % 10);
      num = num/10;
    }
    return sum;
  }
}
