A data structure is a way of organizing and storing data in a computer so that it can be accessed and modified efficiently.
Data structures define the way data is stored, accessed, and manipulated in a computer program.
Examples include arrays, linked lists, stacks, queues, trees, and graphs.
Choosing the right data structure is crucial for optimizing the performance of algorithms and applications.
A linked list is a data structure where each element is connected to the next element through pointers.
Consists of nodes where each node contains data and a reference to the next node
Can easily insert or delete elements without shifting other elements
Examples: singly linked list, doubly linked list, circular linked list

HashSet implements the Set interface in Java.
It uses a hash table for storage.
Example: HashSet
Recursion is a programming technique where a function calls itself in order to solve a problem.

A base case is needed to stop the recursion and prevent infinite loops.
Recursion can be used to solve problems like factorial calculation, Fibonacci sequence, and tree traversal.

Static constructors are called only once when the class is first accessed.
They are used to initialize static variables or perform any necessary setup for the class.
Static constructors do not take any parameters and cannot be called explicitly.
Example: public class MyClass { static MyClass() { // initializatio
