Multithreading is the concurrent execution of multiple threads to achieve parallelism and improve performance.
Multithreading allows multiple threads to run concurrently within a single process.

Background worker is a component that simplifies multithreading by providing a dedicated thread for executing time-consuming tasks in the background...
To create a file and append text, use file handling functions in the programming language.
Open the file in append mode
Write the text to the file
Close the file
A namespace is a container that holds a set of identifiers to avoid naming conflicts.
Namespaces are used to organize code and avoid naming collisions.
They can be nested within other namespaces.
They are declared using the 'namespace' keyword.
They can be used to group related classes, functions, and variables.
For example, the 'std' namespace in C++ contains standard library functions and objects.
Abstract classes are classes that cannot be instantiated and can have both abstract and non-abstract methods. Interfaces are contracts that define the methods that a class must implement.
Abstract classes can have constructors and instance variables, while interfaces cannot.
A class can implement multiple interfaces, but can only inherit from one abstract class.
Abstract classes are used when there is a need for a common ...
Static is a keyword in programming that denotes a variable or method that belongs to the class rather than an instance of the class.
Static variables and methods can be accessed without creating an instance of the class.
Static variables are shared among all instances of the class.
Static methods cannot access non-static variables or methods.
Examples of static methods include Math.max() and Arrays.sort().
C# supports various types of classes including abstract, sealed, static, and partial classes.
Abstract classes cannot be instantiated and are used as base classes for other classes.
Sealed classes cannot be inherited and are used to prevent further modification.
Static classes cannot be instantiated and contain only static members.
Partial classes allow a class to be defined in multiple files.
Other types of classes include...

You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to find and return a list of all pairs of elements where each sum of a pair equals 'S'.
Given an array and a target sum, find pairs of elements that add up to the target sum.
Iterate through the array and for each element, check if the complement (target sum - current element) exists in a hash set.
If the complement exists, add the pair to the result list. Otherwise, add the current element to the hash set.
Sort the pairs based on the first element and then the second element to meet the required output form

Pointers in C/C++ are variables that store memory addresses. They are used to manipulate memory directly and improve performance.
Pointers are declared using an asterisk (*) before the variable name.
Pointers can be used to dynamically allocate memory using functions like malloc() and free().
Pointers can be used to pass variables by reference to functions.

To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
A linked list is a data structure consisting of nodes where each node points to the next node in the sequence.
Create a Node class with data and next pointer
Initialize a head pointer to null
Add nodes by updating next pointers
Traverse the list by following next pointers
