What it does
AlgoCademy combines interactive concept lessons, checked coding steps and independent problem-solving practice.
An interactive lesson asks you to predict or trace an example, then checked coding steps and hints lead toward solving the problem independently. Re-solve it without the guidance to test the transition. Part of every course is free; yearly Pro has a seven-day trial.
