Question

give an example of 2 regular digraph with 5 vertices

Answer 1

Could an example of this be a square and a triangle where the two are non connected? As long as it doesn't specify the graph is connected, I'm assuming it's okay to have two separate figures like this?

and to further elaborate, would it be okay to describe all 2-regular graphs with n components as graphs with vertices having a degree of 2 and all components of the graph being cycles
