# 🚀 Java Data Structures and Algorithms (DSA) & OOPs Questions

![Description of the Image](DATA_STRUCTURE_AND_ALGORITHM/build/classes/image/Screenshot%202024-12-03%20171644.png)

Welcome to my collection of Java DSA and OOPs problem solutions! Here, I’ve solved various challenging problems, implemented efficient algorithms, and demonstrated key object-oriented programming concepts. 🌟

## 📖 Topics Covered

 - 💡 Data Structures: Arrays, Linked Lists, Stacks, Queues, Trees, Graphs.

 - 🔢 Algorithms: Sorting, Searching, Dynamic Programming, Backtracking.

 - 🎓 OOP Concepts: Classes, Inheritance, Polymorphism, Encapsulation, Abstraction.

 - 🤔 LeetCode Problems: Solutions to frequently asked coding interview problems.

 - 📋 Question Patterns

## Here’s a glimpse of the question patterns I’ve worked on:

## 1️⃣ Arrays

 - 🔍 Search in Rotated Sorted Array

   

    _Problem: Search for a target element in a rotated sorted array._

   

    _Solution: Binary Search for O(log n) time complexity._

## 2️⃣ Linked List

- 🔗 Merge Two Sorted Linked Lists

  

     _Problem: Merge two sorted linked lists into one sorted linked list._

  

     _Solution: Use two pointers for optimal merging._

## 3️⃣ Recursion and Backtracking

- 📐 Permutations of an Array

  

     _Problem: Generate all permutations of an array of integers._

  

     _Solution: Recursive backtracking with base and recursive cases._

## 4️⃣ Trees

 - 🌳 Binary Tree Level Order Traversal

   

      _Problem: Return the level order traversal of a binary tree._

   

      _Solution: Use BFS and a queue._

   

# 🎯 Object-Oriented Programming Concepts

## 🛠️ Class and Object

- 📝 Student Management System

  

   _Implemented Features: Add, remove, and view student records._

## 🏠 Inheritance

- 🏢 Employee Management System

  

    _Implemented Features: Hierarchical structure using inheritance (Manager, Engineer)._

## 🚀 Polymorphism

- 📊 Shapes Area Calculator

  _Implemented Features: Overriding calculateArea() for different shapes like Circle and Rectangle._
