The four pillars of Object-Oriented Programming are encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit (class).
Inheritance: Allowing a new class to inherit properties and behavior from an existing class.
Polymorphism: The ability for objects of different classes to respond to the same message in different ways.
Abstraction: H...
TRUNCATE removes all records from a table, while DELETE removes specific records based on a condition.
TRUNCATE is faster than DELETE as it does not log individual row deletions.
TRUNCATE resets the auto-increment value of the table, while DELETE does not.
TRUNCATE cannot be rolled back, while DELETE can be rolled back if used within a transaction.
TRUNCATE does not trigger any delete triggers on the table, while DELE...
Program to reverse a string without using inbuilt methods
Create an empty string to store the reversed string
Iterate through the original string from end to start and append each character to the new string
Return the reversed string
To reverse a string in Python, we can use slicing or the built-in reversed() function.
Using slicing: string[::-1]
Using reversed() function: ''.join(reversed(string))
Both methods return the reversed string

Immutable strings allow for efficient memory allocation and garbage collection.
String pool in Java is possible because of immutability.
Examples of immutable ...
Stack is a data structure that follows Last In First Out (LIFO) principle. Queue is a data structure that follows First In First Out (FIFO) principle.
Stack: LIFO principle, push and pop operations, examples - function call stack, undo feature in software applications
Queue: FIFO principle, enqueue and dequeue operations, examples - printer queue, message queue in operating systems
Encapsulation and polymorphism examples, class types, and requirements for good code.
Encapsulation: hiding implementation details, e.g. private variables in a class
Polymorphism: using a single interface to represent multiple types, e.g. method overloading
Class types: abstract, final, static, inner, anonymous, etc.
Requirements for good code: readability, maintainability, efficiency, scalability, etc.
An operating system is a software that manages computer hardware and software resources and provides common services for computer programs.
