 解答：

    public static void main(String[] args) {
        int value = 13287979;
        System.out.println(reverse(value));
    }

    public static int reverse(int x) {
        long res = 0;
        while (x != 0) {
            res = res * 10 + x % 10;
            x /= 10;
        }
        return (int) res == res ? (int) res : 0;
    }
