UCSD Data Structure and Algorithm

In UCSD's Algorithms class, we can practice algorithms and data structures from different modules each week. Zybook provides us with a fairly rich collection of practice problems that can help us reinforce our review after learning a concept.

🧠 Topics Covered

• Sorting Algorithms (QuickSort, MergeSort, etc.)
• Recursion and Divide & Conquer
• Searching Techniques (Binary Search, Linear Search)
• Dynamic Programming (Knapsack)
• Graph Algorithms (BFS, DFS, Dijkstra)
• Complexity Analysis

📁 Folder Structure

Each folder corresponds to a core module in the course:

• sorting algorithm (Module3)/ – Implementations and complexity comparisons
• recursion/ – Classical recursion examples and use cases
• Module5 Stacks and Queues/ – Step-by-step DP problems with recursion tree analysis
• Module 6 Hash Tables/ – Graph traversals and shortest paths with real-world applications

📌 Why This Repo Matters

• 📚 Serves as my personal review notebook for future research and interviews
• 💡 Built from textbook and lecture knowledge, but written in my own words
• 🔍 Will be expanded with more advanced examples and complexity breakdowns

🚧 Future Plans

• Add time/space complexity visualizations using Matplotlib
• Integrate interactive demos using Streamlit
• Link LeetCode-style problems solved using the same concepts
