Show HN: Visual Learning Tool for Abstract Problem Solving Practice Through DSA (pqdsa.com)

I've been developing this idea for some time now when looking for a way to connect solutions to abstract problems or concepts with a visual learner. This is my first public "version", so please any and all feedback is much appreciated. I hope you enjoy what has come of the idea so far. Most of all enjoy stimulating your mind while having fun and maybe learn a thing or two along the way.
