Module dfs 

Recursive and iterative depth-first search.

Functions

dfs_full

Runs dfs_recursive from every unvisited node, covering all connected components. Returns a single finish-order vec spanning the whole graph.

dfs_iterative

Runs an iterative depth-first search from start using an explicit Stack, calling visitor the first time each node is discovered.

dfs_recursive

Runs a recursive depth-first search from start, calling visitor the first time each node is discovered.
