node_overflow's blog

I made a site called CF Random Unsolved. It gives you a random Codeforces problem you have not solved yet. You can set the difficulty, pick tags, and you do not need any login. Just type your handle and get a random problem.

Why I felt the need to create this

  • Picking a problem from problemset took too long and broke my flow
  • I wanted new problems every time without repeats without scrolling the problemset
  • Filtering by rating or tags felt slow and tedious
  • I needed something that works instantly without login even on my phone

Why it helps

  • No more searching for the next problem
  • Every problem shown is new for you
  • Easy to focus on a rating range or topic
  • No login needed
  • Fast to use and good for daily practice

Updates - Added hide rating/problem tags feature

This site is...actually useful ?

If you are lazy (which you may be or may not be lazy at all) you'd love this..Clean UI and a nice tool.

Overall :: Good site man.

What about adding amount of problems to search so you can get a list for training? It would be useful for practising themes

    Thanks for the suggestion. I might add it later but for now I feel one problem at a time keeps the flow cleaner. One click gets you the next one and it helps maintain focus.
