Whenever we talk about something that is defined by sets, it is important to consider the empty set and how it fits into the definition. A graph of order $1$ has one vertex and (necessarily) no edges, since an edge must join two distinct vertices (but sometimes graphs are allowed to have loops -- edges that join a vertex to itself.

Row and columns b. Vertices and edges c. Equations d. None of these Answer = B 2) The degree of any vertex of graph is . ? Please draw out your explanation. This forces the graph to have zero edges, so E = { }.Again, let G = ( V, E ) be a graph. Then, G is the trivial graph if and only if it has order 1. A directed edge has an arrow from A to B, means A is related to B, but B is not related to A. inclusive Is there any philosophical theory behind the concept of object in computer science?
