using namespace std;
int countSegments(string s)
{
    s.push_back(' ');
    int cnt = 0;
    for (unsigned int i = 0; i < s.size() - 1; i++)
    {
        if (s[i] != ' ' && s[i + 1] == ' ') cnt++;
    }
    return cnt;
}
int main()
{
    int N = 0;
    string s = "";
    cin >> N;
    getchar();
    for (int i = 0; i < N; i++)
    {
        getline(cin, s);
        cout << countSegments(s) << endl;
    }
    return 0;
