I was interviewed in Sep 2024.
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.
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 ...
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...
OOP is a programming paradigm based on objects, enabling abstraction, encapsulation, inheritance, and polymorphism.
OOP stands for Object-Oriented Programming, focusing on objects that combine data and behavior.
Structs are value types, while unions can store different data types but only one at a time.
Abstraction hides complex implementation details, while encapsulation restricts access to certain components.

Easy leetcode question that includes sorting, that needs to written on a piece of paper and submitted in PDF format.
Valid parenthesis time and space complexity and past projects
Approaches for checking valid parenthesis include using a stack or recursion
Time complexity for stack approach is O(n) and space complexity is O(n)
Time complexity for recursion approach is O(2^n) and space complexity is O(n)
Past projects may include developing algorithms for string manipulation or parsing

Basics of all topic percentage algebra
A class is a blueprint for creating objects, which are instances of a class. Objects are instances of a class with specific attributes and behaviors.
Class: Blueprint for creating objects
Object: Instance of a class with specific attributes and behaviors
Differentiation: Class is like a template, object is a specific instance of that template
Pillars of OOPs include Inheritance, Encapsulation, Abstraction, and Polymorphism.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundling data and methods that operate on the data into a single unit.
Abstraction: Hiding the complex implementation details and showing only the necessary features of an object.
Polymorphism: Ability of an object to take on many forms.
Naive algorithm is a simple approach to solving a problem without considering efficiency.
Naive algorithms are straightforward and easy to implement.
They may not be the most efficient solution for complex problems.
Examples include linear search for finding an element in an array and bubble sort for sorting elements.

Program to find duplicate numbers and prime numbers in an array of strings.
Iterate through the array to find duplicate numbers using a hashmap or set.
Check each number in the array for primality using a function that checks divisibility.
Store the duplicate numbers and prime numbers in separate arrays for further processing.
