📚 Tutorial

For solution videos open a Leetcode problem's solutions tab

If you pin the extension in the toolbar & login into ChatGPT in your browser, you can use the following 2 GPT buttons:

• Get your code complexity using ChatGPT
• Fix bugs in your code and return the optimal solution

Please ensure your Leetcode solution is open so the extension can read your code from the page.
