#what is hell is wrong there, i tried all the situation and still it showing WA all the time
#include

using namespace std;

int main()

{

int numberofcases;

cin >> numberofcases;

while (numberofcases--)

{

    int num;
    unsigned long long int total =1;


    int count = num;

    cin >> num;

   

    for (int i = 1; i <= num; i++)

    {

        total *= i;

    }

    cout << total <<endl;

}

return 0;

}
