- Q2. What is singleton
- Ans.
A singleton is a design pattern that restricts the instantiation of a class to one object.
Singleton pattern ensures that a class has only one instance and provides a global point of access to it.
Commonly used in scenarios where only a single instance of a class is needed, such as database connections or logging.
Implemented by creating a static method in the class that returns the same instance every time it is called.

- Q1. What is cross join
- Ans.
Cross join is a type of join operation in SQL that returns the Cartesian product of two tables.
Cross join combines each row from the first table with every row from the second table.
It does not require any matching condition like other types of joins.
Cross join can result in a large number of rows if the tables being joined have many rows.
Example: SELECT * FROM table1 CROSS JOIN table2;
- Q2. Diffrences of class and struct
- Ans.
Classes are reference types with inheritance and access specifiers, while structs are value types with no inheritance and public access by default.
Classes are reference types, while structs are value types
Classes support inheritance, while structs do not
Classes have access specifiers like public, private, protected, while structs are public by default

- Q1. What are the key concepts of Object-Oriented Programming (OOP)?
- Ans.
Key concepts of OOP include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation: Bundling data and methods that operate on the data into a single unit (object).
Inheritance: Allowing a class to inherit properties and behavior from another class.
Polymorphism: Objects of different classes can be treated as objects of a common superclass.
Abstraction: Hiding complex implementation details and showing onl
- Q2. What is the internal working mechanism of a HashMap?
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where the pair will be stored.
If multiple keys hash to the same index (collision), a linked list is used to store these pairs.
To retrieve a value, t...

Create a map to store unique elements
Iterate through the array and add each element to the map as a key
Retrieve the keys of the map to get the unique elements
- Q5. Sets find elements in set
- Ans.
Sets are data structures that store unique elements and can be used to efficiently find elements in the set.
Sets do not allow duplicate elements, so each element in a set is unique.
To find elements in a set, you can use the 'has' method to check if a specific element is present in the set.
Sets are commonly used in programming for tasks like removing duplicates from a list or checking for the presence of specific elemen

- Q1. Internal working of Hash Map
- Ans.
Hash Map is a data structure that stores key-value pairs and uses a hash function to map keys to their corresponding values.
Hash Map uses a hash function to determine the index of the key-value pair in the underlying array.
Collisions can occur when multiple keys hash to the same index, which can be resolved using techniques like chaining or open addressing.
Hash Map typically has a load factor threshold to determine whe...
