CodeLens
See your code think.
Write DSA code and watch it execute live — memory, stack frames, heap objects, pointer arrows, recursion trees — animating as you type. One language-agnostic trace engine drives every panel; Python, C++, and Java plug into it. Reverse execution comes free: the whole run is a scrubbable timeline.
