Top-Down DFS Pattern Visualizers

The Top-Down DFS pattern is a recurring algorithmic shape that appears across coding interviews and competitive problems. Use it when the problem geometry matches its trigger conditions — recognizing the pattern collapses what looks like a hard problem into a familiar template. These visualizers trace Top-Down DFS step-by-step on classics such as Maximum Depth of Binary Tree - Top Down, Path Sum - Top Down, so you can internalize the moves before you ever need them under pressure.
