    Given a positive integer, output its complement number. The complement strategy is to flip the bits of its binary representation.

    Note:
    The given integer is guaranteed to fit within the range of a 32-bit signed integer.
    You could assume no leading zero bit in the integer’s binary representation.

    Example 1:
    Input: 5
    Output: 2
    Explanation: The binary representation of 5 is 101 (no leading zero bits), and its complement is 010. So you need to output 2.

    Example 2:
    Input: 1
    Output: 0
    Explanation: The binary representation of 1 is 1 (no leading zero bits), and its complement is 0. So you need to output 0.
    因为不是简单的补码,所以我们必须从高位开始判断,0跳过,1开始,start便是这个flag。
    然后我们翻转的方法就是对应位异或一个1即可

    /**
     * @param {number} num
     * @return {number}
     */
    var findComplement = function(num) {
        let start = false;
            for (let i = 31; i >= 0; --i) {
                if (num & (1 << i)) start = true;
                if (start) num ^= (1 << i);
            }
            return num;
    };
