This extension is designed to help competitive programmers and developers practice and solve LeetCode problems directly within Visual Studio Code. It supports C++ and Python, allowing users to fetch problem statements, test cases, and run their solutions locally. The extension provides a seamless workflow for debugging and verifying solutions against expected outputs.
Features
Fetch Problem Statement and Test Cases:
Users can fetch problem statements and test cases directly from LeetCode by providing the problem URL.
The extension uses LeetCode's GraphQL API to extract and store test cases locally.
Write and Test Code:
Users can write their solutions in C++ or Python.
The extension allows users to run their code against the fetched test cases to verify correctness.
View Results:
The extension compares the actual output of the user's code with the expected output for each test case.
Discrepancies are highlighted to assist with debugging.
Workflow
Fetch Test Cases:
Run the command CPH: Fetch Test Cases.
Input the LeetCode problem URL.
The extension extracts and stores the test cases locally.
Write and Test Code:
Write your solution in the editor.
Run the command CPH: Run Test Cases to test your solution locally.
View Results:
The extension displays a comparison of actual vs expected outputs.
Debug discrepancies directly in the editor.
