题解：

class Solution {
public:
    vector<int> singleNumbers(vector<int>& nums) {
        int eor = 0;
        for (int num:nums)
            eor ^= num;
        int rightOne = eor & (~eor + 1); // 提取出最右的1
        int onlyOne = 0;
        for (int cur : nums) {
            if ((cur & rightOne) != 0)
                onlyOne ^= cur;
        return vector<int>{onlyOne, eor^onlyOne};
    }
};
