The LeetCodeAutomater project provides an easy way to automate the submission of solutions to LeetCode using your LeetCode session and CSRF token. This repository includes both a Chrome Extension to fetch the required session data and an Executable to run the automation process.

• Automatic Code Submission: Submits your Java solutions directly to LeetCode.

• Skip Premium & Database-Only Questions: Filters out premium-only and database-based problems.

• Progress Tracking: Keeps track of submitted and skipped questions via progress.json and skipped.log.

• Chrome Extension for Token Fetching: Fetches your LeetCode session and CSRF tokens locally for secure authentication.

• Easy Setup & Use: Includes both a Chrome extension and an executable for quick deployment.
