Undirected graph and adjacency matrix, Data Structure & Algorithms

Assignment Help:

Q. Consider the specification written below of a graph G

V(G ) = {1,2,3,4}

E(G ) = {(1,2), (1,3), (3,3), (3,4), (4,1)}

(i) Draw the undirected graph.

(ii) Also draw its adjacency matrix.

Ans:

V(G) = {1,2,3,4}

E(G) = {(1,2),(1,3),(3,3,),(3,4),(4,1)}

(i). The undirected graph is shown as follows:-
