Q1. 
Reverse Array Elements
Given an array containing 'N' elements, the task is to reverse the order of all array elements and display the reversed array.
Explanation:
The elements of the given array need to...read more
Ans. 
Reverse the order of elements in an array and display the reversed array.
• Iterate through the array from both ends and swap the elements until the middle is reached.

• Use a temporary variable to store the element being swapped.

• Print the reversed array after all elements have been swapped.

Tiling Problem Statement
Given a board with 2 rows and N columns, and an infinite supply of 2x1 tiles, determine the number of distinct ways to completely cover the board using these tiles.
You can place...read more
Ans. 
The problem involves finding the number of ways to tile a 2xN board using 2x1 tiles.
• Use dynamic programming to solve this problem efficiently.

• Define a recursive function to calculate the number of ways to tile the board.

• Consider both horizontal and vertical placements of tiles.

• Implement the function to handle large values of N using modulo arithmetic.

• Example: For N = 4, the number of ways to tile the board is 5.

This round had 1 question from DSA where I was supposed to directly write the pseudo code as the question was preety simple. After that , questions revolving around OOPS were asked.

Q1. 
Find Terms of Series Problem
Ayush is tasked with determining the first 'X' terms of the series defined by 3 * N + 2, ensuring that no term is a multiple of 4.
Input:
The first line contains a single in...read more
Ans. 
Generate the first 'X' terms of a series 3 * N + 2, excluding multiples of 4.
• Iterate through numbers starting from 1 and check if 3 * N + 2 is not a multiple of 4.

• Keep track of the count of terms generated and stop when 'X' terms are found.

• Return the list of 'X' terms that meet the criteria.

• Example: For X = 4, the output should be [5, 11, 14, 17].

Q2. What is meant by an interface in Object-Oriented Programming?
Ans. 
An interface in OOP defines a contract for classes to implement, specifying methods without implementation details.
• An interface contains method signatures without any implementation.

• Classes can implement multiple interfaces in Java.

• Interfaces are used to achieve abstraction and multiple inheritance in OOP.

• Example: Java interface 'Runnable' with 'run()' method.

Q3. What is the difference between an abstract class and an interface in OOP?
Ans. 
Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.
• Abstract class can have constructors, member variables, and methods with implementation.

• Interface can only have abstract methods and constants.

• A class can implement multiple interfaces but can only inherit from one abstract class.

• Example: Abstract class - Animal with abstract method 'eat', Interface - Flyable

Q4. What do you mean by virtual functions in C++?
Ans. 
Virtual functions in C++ allow a function to be overridden in a derived class, enabling polymorphic behavior.
• Virtual functions are declared in a base class with the 'virtual' keyword.

• They are overridden in derived classes to provide specific implementations.

• Virtual functions enable polymorphism, allowing objects of different derived classes to be treated as objects of the base class.

• Example: class Animal { virtual void...read more

This round had 1 question from Linked List which was followed by one question from OS and then some questions from OOPS and basic Design Pattern in Java were asked.

Q1. 
Middle of a Linked List
You are given the head node of a singly linked list. Your task is to return a pointer pointing to the middle of the linked list.
If there is an odd number of elements, return the ...read more
Ans. 
Return the middle element of a singly linked list, or the one farther from the head if there are even elements.
• Traverse the linked list with two pointers, one moving twice as fast as the other

• When the fast pointer reaches the end, the slow pointer will be at the middle

• If there are even elements, return the one that is farther from the head node

• Handle edge cases like linked list of size 1 or empty list

Q2. Can you explain piping in Unix/Linux?
Ans. 
Piping in Unix/Linux allows output of one command to be used as input for another command.
• Piping is done using the | symbol in Unix/Linux.

• It allows for the output of one command to be directly used as input for another command.

• Piping can be used to chain multiple commands together to perform complex operations.

• Example: ls -l | grep 'txt' - This command lists files in long format and then filters for files with 'txt' in

Q3. What is dependency injection?
Ans. 
Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
• Dependency injection helps in achieving loose coupling between classes.

• It allows for easier testing by providing a way to mock dependencies.

• There are three types of dependency injection - constructor injection, setter injection, and interface injection.

• Example: In a Java application, a service ...read more

Q4. Can you explain the SOLID principles in Object-Oriented Design?
Ans. 
SOLID principles are a set of five design principles in object-oriented programming to make software designs more understandable, flexible, and maintainable.
• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open/Closed Principle: Software entities should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Objects of a superclass should be replaceable...read more
