Java Data Structures and Algorithms

Welcome to the Java Data Structures and Algorithms repository! This project is a comprehensive implementation of various Data Structures and Algorithms in Java, covering both fundamental concepts and advanced techniques.

Introduction

This repository serves as a resource for learning and implementing Data Structures and Algorithms in Java. Whether you are a beginner or an experienced developer looking to refresh your knowledge, this project provides examples and explanations for each topic.

Data Structures

Arrays

Basic array operations and manipulations.

Linked Lists

Singly linked lists, doubly linked lists, and circular linked lists.

Stacks

Implementation of stacks and common operations.

Queues

Different types of queues, including priority queues.

Trees

Binary trees, binary search trees (BST), and AVL trees.

Graphs

Representation of graphs and common algorithms like DFS and BFS.

Hash Tables

Basic hash table implementation and collision handling.

Heaps

Min and max heaps and heap sort.

Algorithms

Sorting

Bubble sort, selection sort, merge sort, quicksort, etc.

Searching

Linear search, binary search, and variations.

Recursion

Understanding and implementing recursive algorithms.

Dynamic Programming

Solving problems using dynamic programming techniques.

Greedy Algorithms

Solving optimization problems using greedy strategies.

Backtracking

Solving problems by exploring all possible solutions.

Graph Algorithms

Dijkstra's algorithm, Kruskal's algorithm, etc.

Advanced Data Structures

Trie

Trie data structure for efficient string manipulation.

Segment Tree

Building and querying segment trees.

Disjoint Set Union (Union-Find)

Efficiently merging and finding disjoint sets.

Binary Indexed Tree (Fenwick Tree)

Handling range queries and updates efficiently.

Usage
