a) Given a depth-first search tree T, the set of edges in T are referred to as "tree edges" while those not in T are referred to as "back edges". Modify the implementation of the Depth-First Search algorithm to print out the set of tree edges and the set of back edges for the following graph. 1(0 1 1 0 0 1 0) 2 10 10 0 0 0 3110 1 00 1 4 0 0 1 0 00 50 0 0 00 1 1 6 1 0 0 0 10 1 70 0 10 1 1 0

Language : C

(i) Write a C program to implement an algorithm based on Depth-First Search to test the connectivity of a given network. Input: Adjacency matrix (refer to sample program on page 6 for reading in an adjacency matrix) Output: The sequence that vertices are being visited The vertices of each connected component of a given graph The parent of each vertex (a vertex p is the parent of vertex c if c is visited from p) Note: To mark a vertex to indicate if has been visited or not, a one-dimensional integer array, say visit[maxV], where maxV is the size of the array, could be used. visit[i] is set to 0 initially for all i (unvisited), and is set to 1 if visited.
