+# LeetCode Random Problem Link Generator
+
+This Python script retrieves a random coding problem link from LeetCode using the LeetCode GraphQL API. You can specify a difficulty level (easy, medium, or hard) to get a problem link suited to your preference.
+
+## Features
+
+- Fetches a random problem from LeetCode’s problem set.
+- Allows difficulty selection: easy, medium, or hard.
+- Generates a clickable link to the selected LeetCode problem.
+
+## Prerequisites
+
+Ensure you have Python installed. This script also requires the `requests` library. Install it via pip:
+
+```bash
+pip install requests
