Dsa Spaced Repetition

Stop forgetting LeetCode problems you've already solved.

LeetCode Spaced Repetition uses the proven SM-2 spaced repetition algorithm to schedule reviews at optimal intervals — so you retain what you learn with minimal effort.

🧠 HOW IT WORKS
• Visit any LeetCode problem and mark it as solved
• Rate your recall: Forgot, Hard, Good, or Easy
• The algorithm schedules your next review at the perfect interval
• Problems you struggle with come back sooner; easy ones fade away
