        Scanner scanner = new Scanner(System.in);
        long N = scanner.nextLong();
        long reversedNumber = reverseNumber(N);

        long reversed = 0;
        while (N != 0) {
            long digit = N % 10;
            reversed = reversed * 10 + digit;
            N /= 10;
        }
        return reversed;
