Description of the bug

There is a missing test case
when nums: [1, 1, 2]
for this test case some code might give error

Code you used for Submit/Run operation

class Solution {
public:
    int singleNonDuplicate(vector<int>& nums) {
        if (nums.size() == 1) return nums[0];
        
        int left = 0, right = nums.size()-1;
        
        while (left <= right) {
            int mid = left + (right-left) / 2;
            
            int num = mid % 2 == 0 ? mid+1 : mid-1;
            
            if (nums[mid] == nums[num]) { // we are in left part
                left = mid + 1;
                continue;
            }
            
            // right part
            right = mid-1;
        }
        
        return nums[left];
    }
};

// Two Sum
class Solution {
public:
vector twoSum(vector &a, int s) {

}

};
