Why is Laravel's redirect() not working?

Question

Laravel

Connected at the beginning

use App\Http\Requests;
use Illuminate\Http\Request;
use Redirect;

public function test(){
        redirect('1111');
}

Please help me with advice, I just started with Laravel

Answer 1

redirect('where')->send();

Answer 2

redirect is a function. You don't need to connect anything.
You just need to return it:

public function test()
{
  return redirect('123');
}
