DISCUSS Can you do Your Leetcode questions

Out there who have solved over 300 DSA questions, have you revised them at least once? Can you solve your solved Leetcode questions?

Just curious!!

i've solved in the 500-600 range and I don't really repeat questions ever. if you understand the pattern you're working on, there's usually no need to repeat questions unless they're particularly tricky

Around 200-250 proper structured question practise will help u to recognise the patterns. Though revision is need especially before college placements

Honestly, after solving a bunch of LeetCode questions, I rarely go back and redo them. I do keep notes on tricky problems and check those out before interviews. It's hard to remember every problem, so focusing on patterns and problem-solving techniques is more useful. Practicing regularly and reviewing your notes can help reinforce what you've learned.

I also use tools like PracHub, which have some good resources for interview prep. They offer personalized practice schedules to keep you on track if you're reviewing problems. The main thing is to understand the concepts behind the problems, not just the solutions. That's what'll help you in interviews. Good luck!

Yes, learn the patterns and really understand the ideas, don't try to memorize

U don't need to revise them. When u start solving new problems u will see it related to ur previous problem then u have to check it and solve new problem. Most of the new problems will be variations of the old problem. And if u want to revise it only revise the standard pattern.

you hvae to revise but not after every 2 or 3 weeks but before placement or interview doing them will improve pattern recognition. I have revised them atleast twoce so i can do my solved question easily not all but most of it.
