## Description

This project is a VS Code extension that integrates LeetCode problem solving directly into the editor. It functions as a code submission client and competitive programming tool, allowing users to browse, solve, and submit algorithmic challenges without leaving their development environment.

The extension distinguishes itself by managing local workspaces and archives, enabling the organization of problem files and descriptions in configurable local folders. It supports multi-account session management and regional endpoint routing to handle different geographic service instances.

The tool covers several core capability areas, including API integration for fetching problem data and verifying solutions, as well as identity management for authenticating user accounts. It also provides search and indexing for browsing problems by difficulty or tag, and offers a means to access community content and official solutions.
