Guided learning for interview prep
Interactive visualizations with prediction, mistake feedback, and guided learning.
Live demo
A beginner lesson should feel interactive immediately, so the preview below shows prediction mode and mistake detection on the very first array walk.
Live demo
What should happen next?
3 matches the target, so we skip it and keep write where it is.
Watch how the algorithm thinks.
Every move is framed as a question, a reason, and a visible state change instead of a hidden line of code.
Mistake detection
Copying 3 forward would keep a value we are trying to remove.

Guided entry
Your first problem is Remove Element. It is easy, highly visual, and turns the first prediction into a simple keep-or-skip decision with read and write pointers.
