Language : C (i) Write a C program to implement an algorithm based on Depth-First Search to test the connectivity of agiven network.Input: Adjacency matrix (refer to sample program on page 6 for reading in an adjacency matrix)Output:The sequence that vertices are being visitedThe vertices of each connected component of a given graphThe 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, sayvisit[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. b) One application of the depth-first search is for checking acyclicity of a graph. If there is a back edge (an edgenot in the DFS tree T) from some vertex u to its ancestor v in T, the graph has a cycle that comprises the pathfrom v to u via a sequence of tree edges in T followed by the back edge from u to v. Modify your program todetermine if there is a cycle in each connected components of a given graph. Test your program with thegraph given in part(a) above.
