int main()
{
    long long int num;
    int  t;
    cin>> t;
    for(int i=1;i<=t;i++)
    {
        cin>>num;
        num=num*567;

        num=num/9;
        num+=7492;
        num=num*235;
        num=num/47;
        num=num-498;
        num=num/10;
        num=num%10;
        if(num<0) num=num*(-1);
        cout<<num<<endl;
