I kept passing coding questions on paper and failing them on screen. Every tutorial said "just trace it by hand" — but nobody showed me how. DSA Lab is the visualizer I wish existed during my interview prep: paste any code, watch it run step by step, and finally see the algorithm instead of memorizing it. Free, in the browser, no signup — because understanding shouldn't be paywalled.
