I am a software trainee with knowledge in linked list and array list.
I have experience in implementing linked lists and array lists in various programming languages.
Linked lists are dynamic data structures while array lists are static data structures.
Linked lists are efficient for insertion and deletion operations while array lists are efficient for random access.
Examples of programming languages that support linked li
I applied via LinkedIn and was interviewed before Dec 2021. There were 3 interview rounds.
Logical,Quantitative, Aptitude
Write program on reverse a number
Pointers are variables that store memory addresses. They are used to manipulate data structures and improve program efficiency.
Pointers allow for dynamic memory allocation
Pointers can be used to pass values by reference
Pointers can be used to create linked lists
Pointers can be used to access array elements
Example: int *ptr = # // stores address of num variable
Example: void swap(int *x, int *y) { int temp = *x; *x =...
Arrays are fixed in size and contiguous memory while linked lists are dynamic and non-contiguous.
Arrays have constant time access to elements while linked lists require traversal.
Arrays are better for random access while linked lists are better for insertion and deletion.
Arrays use less memory overhead than linked lists.
Example: Array of strings - ['apple', 'banana', 'orange']
Variables are containers that store data values. There are different types of variables in programming.
Variables are declared using keywords like var, let, const.
Variables can store different types of data such as numbers, strings, booleans, objects, arrays, etc.
Variables can be global or local depending on where they are declared.
Variables can be reassigned with new values.
Examples: var age = 25; let name = 'John'; co
I applied via Job Fair and was interviewed before Feb 2023. There were 3 interview rounds.
This is a basic test where you will be asked to solve logical and reasoning questions. Pseudo codes and some basic programs.
Object-oriented programming is a programming paradigm that organizes code into objects that interact with each other.
Encourages modular and reusable code
Focuses on data and behavior encapsulation
Supports inheritance and polymorphism
Examples: Java, C++, Python
Encapsulation is the process of hiding internal details and providing a public interface for accessing and manipulating data.
Encapsulation is a fundamental principle of object-oriented programming.
It helps in achieving data abstraction and data hiding.
By encapsulating data and methods within a class, we can control access to them.
Encapsulation improves code maintainability and reusability.
Example: A class with private ...
Program to find prime number
A prime number is a number greater than 1 that has no positive divisors other than 1 and itself
To check if a number is prime, iterate from 2 to the square root of the number and check if it divides the number evenly
If the number is divisible by any number in the range, it is not prime
Optimization: Only iterate up to the square root of the number, as factors repeat after that
I applied via Campus Placement
A constructor is a special method that is used to initialize objects of a class.
Constructors have the same name as the class they belong to.
They are called automatically when an object of the class is created.
They can be used to set default values for object properties.
Constructors can be overloaded to accept different parameters.
Example: public class Car { public Car() { // constructor code here } }
Java does not support multiple inheritance, but it can be achieved using interfaces.
Java supports multiple interface inheritance
A class can implement multiple interfaces
Interfaces can extend other interfaces
Example: class A implements interface B and C
Example: interface B extends interface D and E

Multiple inheritance cannot be achieved directly in Java, but it can be simulated using interfaces or abstract classes.
Java does not support multiple inheritance of classes
Multiple inheritance can be achieved using interfaces or abstract classes
Interfaces allow a class to inherit from multiple interfaces
Abstract classes can provide partial implementation and can be extended by a single class
