You may assume that each input would have **_exactly_ one solution**, and you may not use the _same_ element twice. You can return the answer in any order. **Example 1:** **Input:** nums = \[2,7,11,15\], target = 9 **Output:** \[0,1\] **Explanation:** Because nums\[0\] + nums\[1\] == 9, we return \[0, 1\]. **Example 2:** **Input:** nums = \[3,2,4\], target = 6 **Output:** \[1,2\] **Example 3:** **Input:** nums = \[3,3\], target = 6 **Output:** \[0,1\] **Constraints:** * `2 <= nums.length <= 104` * `-109 <= nums[i] <= 109` * `-109 <= target <= 109` * **Only one valid answer exists.** **Follow-up:** Can you come up with an algorithm that is less than `O(n2)` time complexity?"},

The `vector` type is a part of the C++ Standard Template Library (STL), and it is not available in C#.To fix this error, you can use the `List` class in C# instead of `vector`. Here's the corrected code:```class Solution{    public List<int> twoSum(List<int> nums, int target)    {        var map = new Dictionary<int, int>();        for (int i = 0; i < nums.Count; i++)        {            int complement = target - nums[i];            if (map.ContainsKey(complement))            {                return new List<int> { i, map[complement] };            }            map[nums[i]] = i;        }        return new List<int>();    }}```I hope this helps!
