🧾 Project Overview

This application serves as a comprehensive suite for solving complex data structure problems using Java. A core requirement of this project was the manual implementation of dynamic data structures (Linked Lists, Queues, Stacks, and Trees) without using the standard java.util.* collection framework.

The project follows the Waterfall development model and uses a simplified Model-View-Controller (MVC) architecture to decouple the algorithmic logic from the Swing-based GUI.

⚙️ Main Modules

1. Node Classification (Andrei): Analyzes a binary tree and classifies nodes based on their number of children (Leaf, Single-child, or Full node) using custom HashTables.
2. Queue of Queues (Valentin): Converts a numerical matrix into a complex hierarchy of primary and secondary queues.
3. Union & Intersection (Bianca): Performs set operations between a binary search tree and a queue, representing the results visually.
4. Tree Paths (Emanuel): Implements a DFS-based algorithm to identify and list all possible paths from the root to the leaves of a binary tree.

🛠️ Technical Specifications

• Language: Java (Pure implementation, no java.util.Collections).
• Interface: Java Swing (JFC) for a robust desktop experience.
• Paradigm: Procedural logic encapsulated in Object-Oriented structures.
• Key Concepts: Recursion, DFS/BFS traversals, memory management via pointers/references, and custom Stack/Queue policies (LIFO/FIFO).
