Total Files: 37 C++ implementations + 1 README

🛠 Tech Stack

• C++: Primary language for all implementations (C++11 or later recommended).
• Compiler: Use g++ or any standard C++ compiler (e.g., GCC, Clang, MSVC).
• No External Libraries: Pure C++ with standard libraries (<vector>, <queue>, <stack>, etc.).

Compilation Instructions:

• Ensure you have a C++ compiler installed (e.g., g++ via MinGW, GCC, or Clang).
• Compile any .cpp file using: g++ filename.cpp -o filename.
• Run the executable: ./filename (Linux/macOS) or filename.exe (Windows).

🚀 Installation

1. Clone the repository:

   git clone https://github.com/H0NEYP0T-466/DSA.git

2. Navigate to the project directory:

   cd DSA

3. Ensure you have a C++ compiler installed:

   • Linux/macOS: Install g++ via package manager
   • Windows: Install MinGW, MSYS2, or Visual Studio
   • Online: Use platforms like Replit, CodeBlocks, or any online C++ compiler

4. Verify installation:

   g++ --version

🚀 Usage

1. Compile a specific file (e.g., bfs_traversal.cpp):

   g++ bfs_traversal.cpp -o bfs_traversal

2. Run the program:

   ./bfs_traversal      # Linux/macOS
   bfs_traversal.exe    # Windows

3. Example workflow:

   # Compile and run queue implementation
   g++ queues.cpp -o queues && ./queues
   
   # Compile and run binary search tree
   g++ binary_search_trees.cpp -o bst && ./bst
   
   # Compile and run graph traversal
   g++ dfs_traversal.cpp -o dfs && ./dfs

4. Explore the code, modify inputs, or use it as a reference for your learning!
