LeetCode Problem Status Checker

This tool automates the process of checking if specific LeetCode problems have been solved. By reading a CSV file with problem links, the script logs into LeetCode, checks each problem's solved status, and updates the CSV file accordingly.

Features

• Automated Problem Status Check: The script uses Selenium to visit each problem page and detect if it’s marked as solved.
• Manual Login: Log into your LeetCode account manually, and the script will continue after login.
• Progress Saving: Updates are saved after each problem check, ensuring progress is not lost in case of interruptions.

Prerequisites

1. Python: Python 3.7 or higher.
2. Google Chrome: Chrome browser needs to be installed.
3. ChromeDriver: Download the compatible version of ChromeDriver for your Chrome browser version.

Setup Instructions

1. Clone the Repository:

   git clone https://github.com/yourusername/leetcode-status-checker.git
   cd leetcode-status-checker

2. Install Dependencies: Install the necessary Python packages:

   pip install -r requirements.txt

3. Download and Configure ChromeDriver:

   • Download the ChromeDriver executable that matches your Chrome version from here.
   • Update the chrome_driver_path in the script to the path of your ChromeDriver executable.

Usage

1. Prepare the Input CSV File:

   • Create a CSV file (e.g., Microsoft.csv) with a column titled problem_link containing the URLs of LeetCode problems you want to check.

2. Run the Script:

   • Run the script in the terminal:

   python main2.py

3. Manual Login:

   • When prompted, log into your LeetCode account manually in the Chrome window that opens. The script will continue automatically once login is detected.

4. Results:

   • The script will check each problem in the CSV and update the file with a new SOLVED column. The CSV file will be saved after each check to ensure progress is preserved.

CSV Format

The input CSV file should have the following format:

problem_link
https://leetcode.com/problems/abc/
https://leetcode.com/problems/xyz/

After running the script, a SOLVED column will be added:

problem_link	SOLVED
https://leetcode.com/problems/abc/	Yes
https://leetcode.com/problems/xyz/	No

Troubleshooting

• Login Issues: Ensure that you are able to log into LeetCode manually before running the script.
• ChromeDriver Errors: Ensure that the version of ChromeDriver matches your Chrome browser version. You may need to update chrome_driver_path if ChromeDriver is located elsewhere.
• Timeouts: If the script times out frequently, try increasing the wait time or checking for internet connection stability.
