StepWise
100+ data structures and algorithms, every step narrated with its pseudocode line and variables; step back, share as a link, embed in Canvas.
Apps / Pathfinding Playground
Pathfinding Playground
Draw a grid and race BFS, Dijkstra, A* and friends across it.
What it does
Paint walls and slow, muddy squares on a grid, or generate a maze, then watch five classic route-finding methods (breadth-first, depth-first, Dijkstra, greedy best-first and A*) explore it step by step, with a plain-English commentary on what each one is doing and why. Run two side by side to see which finds the cheaper route and how much ground each covers first. Any map can be shared as a link, so teachers can hand the same puzzle to a whole class.
Good to know
Moves go up, down, left and right on a square grid only, so it does not show diagonal moves or real road maps.
More for learners
Poincaré Paint
Draw in the hyperbolic disk and watch every stroke tile to infinity.
Digital Student Assistant
An AI teaching assistant that asks before it tells and won’t hand over homework. Yusuf Pisan’s data structures students at UW Bothell use it now.
