WebSay, the node is u, now traverse each node in the adjacency list of u. Say, the node is v (i.e. u -> v) . In the transpose graph, add u to adjacency list of v (there exists and edge from v to u i.e. v -> u). Repeat this process for all the nodes (& their respective adjacency lists) in the graph until the transposed graph has been obtained. grants for immigration services
