Before focusing on graph traversal, we first determine how to represent a graph. In fact, there are mainly two ways to represent a graph, either using adjacency lists or adjacency matrix. An adjacency list is an array of lists. Each list corresponds to a node of the graph and stores the ...

It is like atree. Traversal can start from any vertex, say Vi. Vi is visited and then all vertices adjacent to Vi are traversed recursively using DFS. Since a graph can have cycles. We must avoid revisiting a node. To do this, when we visit a vertex V, we mark it visited. A node...
Let's run a depth-first traversal of the graph. It can be implemented by a recursive function, perhaps something like this: 1 function visit(u): 2 mark u as visited 3 for each vertex v among the neighbours of u: 4 if v is not visited: 5 mark the edge uv 6 call visit(v) Here...
