Pointers are variables that store memory addresses of other variables in programming languages like C, C++, and Java.
Pointers allow direct access to memory locations, enabling efficient manipulation of data.
They are used for dynamic memory allocation, passing parameters by reference, and creating data structures like linked lists and trees.
Example: int *ptr; // declaring a pointer variable
Example: ptr = # // assign...

An interceptor in Angular is a service that can be used to intercept and modify HTTP requests and responses.
Interceptors can be used to add headers, modify requests, handle errors, etc.
They are implemented as classes that implement the HttpInterceptor interface.
Interceptors are added to the HttpClientModule providers array in the app module.
Example: LoggingInterceptor implements HttpInterceptor to log all HTTP requests

I have used Redux for state management in my previous projects.
Redux is a predictable state container for JavaScript apps.
It helps in managing the state of the application in a single immutable state tree.
Actions are dispatched to update the state and components can subscribe to changes.
Selectors can be used to efficiently extract data from the state tree.
Middleware can be added to handle asynchronous actions.

An abstract class is a class that cannot be instantiated and may contain abstract methods that must be implemented by its subclasses.
Cannot be instantiated directly
May contain abstract methods
Used as a blueprint for other classes
Abstraction is the process of hiding complex details and showing only the essential features of an object or system.
Abstraction allows us to focus on what an object does, rather than how it does it
It helps in simplifying complex systems by breaking them down into smaller, more manageable parts
Examples of abstraction include using a car without needing to understand its internal combustion engine, or using a smartphone
QuickSort is one of the best sorting algorithms with an average time complexity of O(n log n).
QuickSort is a divide and conquer algorithm that works by selecting a 'pivot' element and partitioning the array around the pivot.
It has an average time complexity of O(n log n) and a worst-case time complexity of O(n^2).
Example: ['apple', 'banana', 'cherry', 'date', 'fig'] can be sorted using QuickSort.
Example: ['3', '1', '4'...
Bubble sorting has a time complexity of O(n^2) for a sorted list.
Bubble sorting has a worst-case time complexity of O(n^2) for a sorted list.
The time complexity does not change even if the list is already sorted.
Example: If we have a sorted list of size n, bubble sorting will still take O(n^2) time.
