Pseudoforest

A pseudoforest is a specific type of graph in graph theory. It is defined as a graph where every connected component has at most one cycle. In other words, a pseudoforest can be thought of as a collection of trees (which have no cycles) and, possibly, some additional edges that form one cycle in each connected component. To break it down further: - **Trees**: A tree is an acyclic connected graph. It has no cycles.
