    int n = i;
    int j;
    string[] stringList = h.Split(" ".ToCharArray(),
                                  StringSplitOptions.RemoveEmptyEntries);
    int m = stringList.Count();
    for (j = 0; j < m; j++)
    {
        int c = 0;
        for (k = 0; k < m; k++)
        {
            if (string.Compare(stringList[j], stringList[k]) == 0)
            {
                c = c + 1;
            }
        }
    }
