• 🌐 Fetch input and output test cases directly from a LeetCode problem URL.
• 🗂️ Avoid redundancy by reusing existing test case files.
• 💾 Automatically saves test cases into files for easy access:
  • <problem_name>_inputs.txt: Contains input test cases.
  • <problem_name>_outputs.txt: Contains expected output test cases.
• 🧮 Handles arrays and matrices automatically by adding their sizes to the input file. No manual edits are needed!
• ⚡ Shortcut: Use Ctrl+Shift+P and select CPH: Fetch Test Cases.

✏️ 2. Modify Test Cases

• Easily edit input and output test cases using the generated files.
• Supports running multiple custom test cases for flexibility.

⚙️ 3. Run and Compare

• 🏃 Run your solution directly from the editor and compare outputs effortlessly.
• Detailed output includes:
  • 🔹 Input test case
  • 🔹 Expected output
  • 🔹 Your output
  • 🔹 Pass/Fail status for each test case

🌍 4. Multi-Language Support

Supports popular programming languages:

• 🟦 C++
• 🟩 Python

🛠️ Usage

📥 Fetch Test Cases

1. Open a workspace in Visual Studio Code (a folder must be opened to avoid errors).
2. Open the Command Palette (Ctrl+Shift+P).
3. Run the command: CPH-Leetcode: Fetch Test Cases.
4. Enter the LeetCode problem URL (e.g., https://leetcode.com/problems/two-sum).
5. Select the programming language (C++ or Python).
6. The extension generates:

• <problem_name>.<extension>: A code template file.
• <problem_name>_inputs.txt: Contains input test cases.
• <problem_name>_outputs.txt: Contains expected output test cases.

⚙️ Run and Compare

1. Write your solution in the generated code file.
2. Open the Command Palette (Ctrl+Shift+P).
3. Run the command: CPH-Leetcode: Run and Compare.
4. The extension will:

• Execute your code for each input test case.
• Compare outputs with the expected results.
• Display detailed results in the output channel, including:
  • Input test case
  • Expected output
  • Your output
  • ❌ Test case status (Pass/Fail)

🛠️ Example Workflow

1. Fetch Test Cases:

• URL: https://leetcode.com/problems/two-sum
• Files Generated: - two-sum_inputs.txt
  - two-sum_outputs.txt
  - two-sum.cpp (or two-sum.py)

2. Write Code:

• Open two-sum.cpp (or two-sum.py).
• Implement your solution in the provided template.

3. Run and Compare:

• Execute the Run and Compare command.
• View the results in the output channel: - Input
  - Expected Output
  - Your Output
  - Test case status (Pass/Fail)

🧰 Extension Commands

⚙️ Requirements

• Programming Languages:
  • 🟩 Python: Ensure python is installed and added to your system's PATH.
  • 🟦 C++: Ensure g++ is installed and added to your system's PATH.

🔮 Future Enhancements

• Extend support for more programming languages.
• Add submission commands for direct LeetCode integration.
• Now the extension is not getting packaged properly so in future this can be done properly so that uiser can directly install extension from vscode extension download.
