# Examples

Runnable copy-paste-friendly examples for `@buzzr/dfs-engine`. In your own project:

```bash
npm install @buzzr/dfs-engine
```

Then copy any of the files in this directory and run with `npx tsx <file>` (or after `tsc` compilation).

Each script prints its output to stdout — no setup, no mocks, no fixtures.
