今晚的360第二题编程题

今晚的360第二题编程题，考完后改了一下，现在是对的吗？

#include<iostream>
#include<vector>
#include<algorithm>

using namespace std;

int main()
{
    int T;
    long r, g, b;
    vector<long> result;
    cin >> T;
    for (int i = 0; i < T; i++)
    {
        vector<long> num;
        long count = 0;
        cin >> r >> g >> b;
        num.push_back(r);
        num.push_back(g);
        num.push_back(b);
        sort(num.begin(), num.end());

        if (num[2] == 0)
        {
            count = 0;
        }
        else
        {
            if (2 * (num[0] + num[1]) <= num[2])
                count = num[0] + num[1];
            else
            {
                long min_num = num[0];

                long temp_max = 0;
                long temp1 = num[2] - num[0];
                long temp2 = num[1] - num[0];
                if (temp1 >= 2 * temp2)
                    temp_max = temp2;
                else
                    temp_max = temp1 / 2;
                count = min_num + temp_max ;
            }            
        }
        result.push_back(count);
    }    

    for (int i = 0; i < T; i++)
    {
        cout << result[i] << endl;
    }

    return 0;

}
