Custom LeetCode Generator 🚀

A Chrome extension that lets you find a random LeetCode problem based on your exact preferences. Stop searching and start solving!

---

🎯 Features

This extension adds a popup to your browser that lets you filter for the exact kind of problem you want to practice:

• By Topic: (e.g., Array, String, Hash Table, Graph)
• By Difficulty: (Easy, Medium, Hard)
• By Solved Status: (Not Solved, Solved/Accepted, Attempted)
• By Premium Status: (All Problems, Free Only, Premium Only)

Click "Generate Problem," and the extension will instantly open a new tab with a random problem that matches all your filters.

If no problems match your criteria (e.g., "Hard" + "Solved" + "Array" and you haven't solved any), it will show you a "No problems found" message.

🛠️ How It Works

This extension doesn't scrape the LeetCode website. Instead, it uses LeetCode's internal GraphQL API—the same one the official website uses.

1. It reads your preferences from the popup.
2. It makes a query to the API to find the total number of problems that match your filters.
3. It picks a random number between 0 and that total.
4. It makes a second query to fetch the one problem at that random position.
5. It opens the problem's URL (https://leetcode.com/problems/...) in a new tab.
