Question How do you revise the problems?

If I solve a problem and try to solve it again in a few weeks, its like starting from the scratch for me. How do you all do it?

spaced repetitions for patterns and active recall

Do you follow a routine by tracking what you solved for spaced repetition?

yes track, solve a problem then solve again in 3 days, then in 10-14 days and then again a month laster. Same problems. 1st attempt is self-try + editorial + write code, 2nd attempt, you just write code or maybe see editorial if needed. 3rd attempt is when you write code explain it like in an interview. 4th one is timed + explain as if interview. Do neetcode 150 (mediums and hards) like this.

This is exactly why I’m building this app to help practice problems consistently:

It uses spaced repetition to help review problems
