Every Day You Don't Revise, Your Code Dissolves
Test what happens to a solved LeetCode Hard problem (146. LRU Cache) as days pass without scheduled spaced repetition.

// ⚠️ CAUTION: SEVERE MEMORY DECAY DETECTED
// [CRITICAL ERROR]: Solution logic completely dissolved.
// ✖ Result: Would fail technical interview & live coding.
// Action Required: Immediate Spaced Repetition Needed.

The Science Behind Never Forgetting
Hermann Ebbinghaus proved human memory decays exponentially within 48 hours. ALGONEX uses algorithmically timed spaced reviews to turn temporary memory into permanent intuition.
