📘 LeetCode Database Tracker

A simple web app built with Streamlit and SQLite to manually track progress on LeetCode Database problems.
This project is designed as a personal tool for practicing SQL and data visualization, while keeping problem-solving progress organized.

✨ Features

• Add and update problems with:
  • Problem ID
  • Title
  • Difficulty (Easy, Medium, Hard)
  • Status (To Do, In Progress, Done)
  • Notes
• Store progress in a local SQLite database (leetcode.db)
• View all problems in a sortable, filterable table
• Visualize completion statistics by difficulty with charts
• Database file is excluded from Git (.gitignore), so personal progress remains private
