- def apply[A](nodes: Set[A])(implicit arg0: GetParents[A]): Set[A]
Find the lowest common ancestor(s) for a set of nodes in a directed acyclic graph (DAG).
Find the lowest common ancestor(s) for a set of nodes in a directed acyclic graph (DAG).
- returns
Set.empty if given nodes have cyclic dependencies Algorithm: 1) for each relevant node, find their recursive parents 2) create the intersection of all of those sets 3) the LCA are those nodes, that do not have any children in that set based on https://www.baeldung.com/cs/lowest-common-ancestor-acyclic-graph
