Data Structures & Algorithms Journey
I’m building strong mental models through daily practice and creating visual learning tools.
Active Practice
- Daily LeetCode problems with pattern recognition
- Generating study guides that break down problems into core mental models
- Building AlgoViz - Visual algorithm simulator to see concepts in action
- Building AlgoJit - Spaced repetition system for DSA retention
Approach: Each study guide distills problems into strong analogies and mental models. The goal is deep understanding over rote memorization.
