CoR pattern appropriate dependency Injection with Symfony

I was working on a suitable example of the CoR(Chain-of-responsibility) pattern. I learned that it is often used as middleware layer in MVC.

I am trying to write a middleware layer suitable for the pattern.

I have set my scenario regarding the implementation of the pattern as follows: The classes defined in the controller method as Annotations are linked to each other with chains, and each class performs a task and moves on to the next task. CoR(Chain-of-responsibility) pattern implementation known so far.

When I look at the examples, none of the classes used as middleware have been injected with Depency injection.

My scenario is as follows: An "@Middleware()" annonation is defined to the Controller method. Sample

/**
 * @Route("/", name="test")
 * @Middleware({"App\Middleware\MiddlewareOne","App\Middleware\MiddlewareTwo"})
 */
public function test()

Then I get annotations in the "onKernelController" method with ControllerListener and create the classes defined here with a foreach loop and connect them to each other.

Below you will see the sample code blocks, respectively.

The problem I'm having here is How can I give the ContainerInterface or a Service class that I created in the constructor of the MiddlewareOne class to the constructor of this object?(I do not know which services are coming, a fixed service is not coming)

class ControllerListener
{
    /**
    * @param \Symfony\Component\HttpKernel\Event\ControllerEvent $controllerEvent
    */
    public function onKernelController(ControllerEvent $controllerEvent)
    {

        MiddlewareManager::handle($controllerEvent);
    }

}

class MiddlewareManager
{


   public static function handle(ControllerEvent $controllerEvent)
   {
       $containerBuilder = new ContainerBuilder();
       if (!is_array($controllers = $controllerEvent->getController())) {
            return;
       }

       $reader = new AnnotationReader();
       $request = $controllerEvent->getRequest();
       $content = $request->getContent();

       [ $controller, $methodName ] = $controllers;
       $reflectionClass = new \ReflectionClass($controller);
       $classAnnotation = $reader
              ->getClassAnnotation($reflectionClass, Middleware::class);
       $reflectionObject = new \ReflectionObject($controller);
       $reflectionMethod = $reflectionObject->getMethod($methodName);
       $methodAnnotation = $reader
            ->getMethodAnnotation($reflectionMethod, Middleware::class);

       if (!($classAnnotation || $methodAnnotation)) {
            return;
       }
       $middlewareList = $classAnnotation->getMiddleware()['value'];
                
        $middleware = null;
        $temp = null;
        foreach ($middlewareList as $class){
            if ($middleware === null){
                $middleware = new $class();
                $temp = $middleware;
                continue;
            }
            $class = new $class();
            $temp->next($class);
            $temp = $class;
        }
        return $middleware;
    
    }


}

class DumpOneMiddleware implements Middleware
{

  /** @var \App\Middleware\Middleware */
  private $next;
  /** @var \App\Service\ExampleService */
  private $exampleService;

  public function __construct(ExampleService $exampleService)
  {
      $this->exampleService = $exampleService;
  }

   /**
   * @param \App\Middleware\Middleware $next
   * @return \App\Middleware\Middleware
   */
   public function next(Middleware $next)
   {
       $this->next = $next;
       return $next;
   }

   /**
   * @param \Symfony\Component\HttpFoundation\Request $request
   */
   public function handle(Request $request)
   {
    if (!$this->next) {
        return true;
    }
    return $this->next->handle($request);
  }
}

Here I can export Container object via ControllerListener (to all middleware classes). But if I want to add another service, how can I do it?

When I examined these and similar topics, I came to the conclusion that I should look at the strategy pattern and Compailer Pass issues. But these topics didn't help me much or I couldn't understand.

I would be very grateful if you could indicate the deficiencies or mistakes in the scenario I applied and show with an example how I can inject Dependecy into the objects I created dynamically.

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
