a) List of Strongly connected components are (a, c, f) , (b, d) and e
Strongly-Connected Components are nothing but A Graph G is strongly connected if, for every u and v in V, there is some path from u to v and some path from v to u.
Adjacency Matrix Representation of given Directed graph is as follows
| a | b | c | d | e | f | |
| a | 1 | 0 | 1 | 0 | 1 | 0 |
| b | 0 | 0 | 0 | 1 | 1 | 0 |
| c | 0 | 0 | 0 | 1 | 1 | 1 |
| d | 0 | 1 | 0 | 0 | 0 | 0 |
| e | 0 | 0 | 0 | 0 | 1 | 0 |
| f | 1 | 0 | 0 | 0 | 0 | 0 |
