Show HN: I made a spaced repetition tool to master coding problems

As you solve LeetCode questions, you can mark them as hard, medium, or easy. The tool will then recommend questions you should review based on (1) how hard the question was for you and (2) how much time has passed since you last reviewed it. I'd recommend normally attempting LeetCode problems and just marking them as hard, medium, or easy for you at first so the tool knows which problems to recommend you review!

Here's the theory behind spaced repetition and learning if interested: https://www.codecademy.com/article/spaced-repetition

Hey guys! I'm Shreya.

I recently noticed that many people that solve leetcode style problems to learn programming patterns tend to save links to problems they'd like to try again later on google docs/notes.

However, this doesn't help them remember to try these problems again or differentiate between problems that are more urgent to revise.

Built this tool to help solve this inefficiency!

how is this different from sharing an anki deck?

So many people coming up with different Anki's. For me Anki is so flexible that I don't think anything will ever easily beat it.

Or just use this public Anki deck as a base and add your own questions to it: https://ankiweb.net/shared/info/1223170466

Seems nice, congrats! How does the recommendation algorithm work?

Off topic: is spaced repetition ever used for training LLMs? Does that even make sense?

Thank you

Will it stop recommending if you have mastered the problem? Or will it give a new problem to solve ?

Training for multiple epochs is a bit like that :)

I'm about to start the leet code grind for interviews coming up and I'll give this a shot. I found your feedback form on your website but would be nice to post it in your post here as well. Cheers.
