- 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. Internal working of hashmap
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to efficiently 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 it will be stored.
If multiple keys hash to the same index, a linked list is used to handle collisions.
To retrieve a value, the key is hash...
