Preparing interactive visualizations...
Step-by-step interactive animations for every major algorithm and data structure. Watch the logic unfold, not just the code.
Textbooks give you pseudocode. We give you the algorithm alive — animated, explained, and yours to control.
Pause, rewind, and step through every comparison, swap, and decision. Watch algorithms think.
Colour-coded bars, nodes, and cells show exactly what's happening at every tick of the algorithm.
Best, average, and worst-case Big-O breakdowns alongside every visualizer, not buried in theory.
Syntax-highlighted Python implementations with copy-to-clipboard on every algorithm page.
Quick-reference tables for every algorithm category — search, filter, and compare at a glance.
Randomise arrays, change sizes, and adjust speed sliders to build intuition with your own data.
151 interactive visualizers across 2 subjects — each with animations, explanations, code and an active-recall quiz.
