I don't remember the exact coding platform, but there were two questions, both focused on strings. The first question required converting an integer to a Roman numeral, and the second question, which I don't recall, was of medium to hard difficulty.

Q1. What is Oops? What is the difference between Abstaction and Encapsulation? What is the difference between virtual fucntion and interface? What is polymorphism? What is the difference between exception an...read more
Ans. 
OOP is a programming paradigm based on objects, encapsulating data and behavior, enhancing modularity and reusability.
• OOP stands for Object-Oriented Programming, focusing on objects that combine data and methods.

• Abstraction hides complex implementation details, while encapsulation restricts access to certain components.

• A virtual function is a member function in a base class that you can override in a derived class; an ...read more

Ans. 
Data structures are ways to organize and store data for efficient access and modification.
• Data structures include arrays, linked lists, stacks, queues, trees, and graphs.

• Arrays are fixed-size, contiguous memory locations; linked lists are dynamic and consist of nodes.

• Linear data structures (like arrays and linked lists) have a sequential relationship; non-linear (like trees and graphs) do not.

• Stacks follow Last In Firs...read more
