Graph[{1\[DirectedEdge]2,2\[DirectedEdge]3,3\[DirectedEdge]2,3\[DirectedEdge]4,4\[DirectedEdge]1,4\[DirectedEdge]5,4\[DirectedEdge]2},\
VertexLabels->"Name"]

What is the adjaceny matrix C for the above graph? What is its column-normalized form D?
Form the vector r=[0.2,0.2,0.2,0.2,0.2] and compute (D^20)r. What does this tell you about the
nodes’ importance?
