CFtrends : A website for fetching fresh CF problems from past 1 year!!!
By Traverser_25, history, 6 months ago, In English

LINK:CFtrend REPO:githubRepo

  1. I wanted to solve new problems which are from last year,which are new
  2. I noticed that many coders share this desire.
  3. So, I created a website that periodically scrapes problems and compiles them into a list.
  4. Users can search for problems by rating.
  5. The website is still in the development phase, with more problems being added regularly.
  6. It's built using Flask, a single HTML page, and a SQLite3 database.
  7. I hope it proves useful to some people.
  8. In the future, I plan to implement a feature to scrape unrated problems and fetch their ratings from another source.
  9. I also aim to set up email notifications to inform users about new problems.
  10. Thank you, and happy coding!

Usage:- Goto site, enter rating in search bar that u want to solve and press the search button,you will have the list of problems.

A small bug. When you type in the rating and press enter it just refreshes the screen instead of searching. Nice work anyway!

    I didn't use codeforces api ,

    I used webscraping to extract rating wise problem from each contest from past year.

    I don't likned api to database, i m running a cronjob monthly to fetch problems and update database in python, my database is sqlite3 db file, simpler and more easy to upadate.

I have a suggestion you can create a toggle button to switch to light/dark mode. Your current UI looks old. Don't mix up white and black,keep everything white or keep it black.
