📚 Advanced Data Structures & Algorithms in C++ 📖 Overview

The Advanced Data Structures & Algorithms project is a collection of C++ programs that demonstrate efficient problem-solving techniques commonly used in competitive programming, coding interviews, and software development. It covers important concepts such as Hashing, Two Pointers, Sliding Window, Prefix Sum, and Hash Collision Handling, along with their implementations and practical applications.

This project was developed to strengthen algorithmic thinking and improve coding skills by implementing optimized solutions using C++. Each concept is explained through clean, modular, and easy-to-understand code.

✨ Features Implemented entirely in C++ Covers advanced data structures and algorithmic techniques Well-structured and readable code Efficient time and space complexity Beginner-friendly implementations Suitable for coding interviews and competitive programming Includes multiple problem-solving approaches 🛠 Technology Used C++

C++ is used to implement all algorithms and data structures. The project utilizes the Standard Template Library (STL), including containers such as vectors, unordered maps, sets, queues, stacks, and other utility functions to create efficient solutions.

📚 Topics Covered 🔹 Hashing Hash Maps Hash Sets Frequency Counting Duplicate Detection Counting Occurrences Lookup Optimization 🔹 Two Pointer Technique Opposite Direction Pointers Fast and Slow Pointer Pair Sum Problems Removing Duplicates Palindrome Checking Array Traversal 🔹 Sliding Window Fixed Size Window Variable Size Window Maximum Sum Subarray Longest Substring Problems Window Expansion and Shrinking 🔹 Prefix Sum Prefix Sum Arrays Range Sum Queries Prefix XOR Running Sum Efficient Query Processing 🔹 Hash Collision Collision Concept Separate Chaining Open Addressing Linear Probing Quadratic Probing Double Hashing 🎯 Learning Objectives
