$2.($a$)$ Show the values that you get if you run two rounds of computing hub and authority values on the network of Web pages in Figure $14\mathrm{.}16.($That is$,$ the values computed by the $\backslash ($ k $\backslash )-$step hub$-$authority computation when we choose the number of steps $\backslash ($ k $\backslash )$ to be $2.)$

Figure $14\mathrm{.}16$: A network of Web pages.

Show the values both before and after the final normalization step, in which we divide each authority score by the sum of all authority scores, and divide each hub score by the sum of all hub scores. $($We will call the scores obtained after this dividing$-$down step the normalized scores. It's fine to write the normalized scores as fractions rather than decimals.$)$
