DSA C++ Practice Repository

Welcome to my professional Data Structures and Algorithms (DSA) practice workspace. This repository contains solutions to high-quality DSA problems optimized for placement preparation and competitive programming, built cleanly using Modern C++ and managed with CMake.

---

📂 Repository Structure

The project is split into 24 core categories. Each category contains 30 distinct, high-quality problems divided by difficulty levels (Easy, Medium, Hard) with each and every folder and file is configured with CMake.

🚀 How to Build and Run Problems

This repository uses a build directory isolation approach via CMake to keep source files completely clean from compiled artifacts.

Prerequisites or Dependencies

Ensure you have a modern C++ compiler (supporting C++17 or higher) and CMake installed on your machine.

1. Configure and Build

Open your terminal inside the root directory (dsa-cpp-practice/) and run:

# Create and enter the build folder
mkdir build && cd build

# Generate build configuration files
cmake ..

# Compile the entire project
cmake --build .

2. Execute an Individual Problem

Once compiled, you can execute individual problem files directly from your terminal inside the build/ folder:

• Linux / macOS:

./src/01_introduction/01_two_sum

• Windows:

.\src\01_introduction\01_two_sum.exe

3. 📝 How to Add a New Problem

1. Drop your new .cpp problem file inside its corresponding category folder under src/.
2. Open the CMakeLists.txt file inside that specific category folder.
3. Append a new executable rule at the bottom:

add_executable(problem_name problem_name.cpp)

4. Re-run cmake --build . inside your build/ directory to compile it instantly.
