    int max = 0;
    int boundary = -1;
    for (int i = 0; i < 32; i++) {
        int t = num & 1;
        num = num >> 1;
        if (t == 1) {
            if (boundary == -1) {
                boundary = i;
            } else {
                max = Math.max(max, i - boundary - 1);
                boundary = i;
            }
        }
    }
    return max;
}
