protected is an access modifier in object-oriented programming that restricts access to members within the same package or subclasses.
protected is one of the four access modifiers in Java, along with public, private, and default.

Objects are instances of classes in object-oriented programming.
They encapsulate data and provide methods to manipulate that data.
Objects can interact with each other through method calls and message passing.
Examples of objects include a car, a person, or a bank account.
Public is a keyword in programming languages that denotes the accessibility of a class, method, or variable.
Public is one of the access modifiers in object-oriented programming.
It allows the class, method, or variable to be accessed from any other class or package.

I appeared for an interview in Apr 2025, where I was asked the following questions.
- Q1. How can you remove duplicate numbers from a list?
- Ans.
You can remove duplicates from a list in Python using various methods like set(), list comprehension, or loops.
Use set(): Convert the list to a set and back to a list. Example: list(set([1, 2, 2, 3])) results in [1, 2, 3].
List comprehension: Create a new list while checking for duplicates. Example: [x for i, x in enumerate(original_list) if x not in original_list[:i]].
Using a loop: Iterate through the list and append u...
- Q2. How can I count the common words between two given strings?
- Ans.
Count common words in two strings by splitting, using sets, and finding intersections.
Split both strings into lists of words using the split() method.
Convert the lists to sets to eliminate duplicates.
Use set intersection to find common words.
Example: 'hello world' and 'world of python' -> common words: {'world'}.
- Q3. What is the difference between a module and a package in programming?
- Ans.
A module is a single file of Python code, while a package is a collection of modules organized in a directory structure.
A module is a single Python file (e.g., `math.py`).
A package is a directory containing multiple modules and a special `__init__.py` file (e.g., `mypackage/`).
Modules can be imported directly (e.g., `import math`).
Packages allow for hierarchical organization of modules (e.g., `from mypackage import mym...
