Explain the representations of graph.
The different ways of representing a graph is:
Adjacency list representation: This representation of graph having of an array Adj of |V| lists, one for every vertex in V. For each uεV, the adjacency list Adj[u] having all the vertices v such that there is an edge (u,v)ε E that is Adj[u] having of all the vertices adjacent to u in G. The vertices in every adjacency list are stored in an arbitrary order.
The time needed to delete a node x from a doubly linked list having n nodes is O (1)
