Exercise $5\mathrm{.}2\mathrm{.}4$: Consider a Web graph that is a chain, like Fig. $5\mathrm{.}9,$ with n nodes. As a function of k$,$ which you may assume divides n$,$ describe the representation of the transition matrix for this graph, using the method of Section $5\mathrm{.}2\mathrm{.}4($Mining Massive Datasets Textbook$).$ Figure $5\mathrm{.}9$: A chain of dead ends
