Degree, clustering and coefficient

1. Degree, Clustering Coefficient and Components (a) Consider an undirected network of size N in which each node has degree k = 1. Which condition does N have to satisfy? What is the degree distribution of this network? How many components does the network have? (b) Consider now a network in which each node has degree k = 2and clustering coefficient C = 1. How does the network look like? What condition does N satisfy in this case?
