Pascal's Triangle

Write a method that given an integer n, would return the corresponding row n of pascal's triangle.
Example Input: 4, Output: 1 4 6 4 1

vector<int> PascalTriangle(unsigned int n)
{
    vector<int> res;
    res.push_back(1);
 
    if (n == 0)
        return res;
    if (n == 1)
    {
        res.push_back(1);
        return res;
    }
 
    vector<int> temp = PascalTriangle(n - 1);
 
    for (int i = 0; i < n - 1; i++)
        res.push_back(temp[i] + temp[i + 1]);
 
    res.push_back(1);
    return res;
}
