Expert Solution
Step 1

Given: Graph G

To find:

(a) Adjacency matrix A of G.

(b) Using matrix A and its power, we have to find the number of walks of length exactly 3 starting at v2 and ending at v4.

(c) Using matrix A and its power, we have to find the number of walks of length at most 3 starting at v2 and ending at v4.
