Directed Graph through DFS each vertex assigned discovery and finishing time


Write a C Program for Traversing a Directed Graph through DFS recursively, each vertex assigned discovery and finishing time. Here’s simple Program for Traversing a Directed Graph through DFS each vertex is assigned a discovery and finishing time.


Depth First Search (DFS)


Depth First Search (DFS) algorithm traverses a graph in a depthward motion and uses a stack to remember to get the next vertex to start a search, when a dead end occurs in any iteration.

It employs the following rules.

  • Rule 1 − Visit the adjacent unvisited vertex. Mark it as visited. Display it. Push it in a stack.
  • Rule 2 − If no adjacent vertex is found, pop up a vertex from the stack. (It will pop up all the vertices from the stack, which do not have adjacent vertices.)
  • Rule 3 − Repeat Rule 1 and Rule 2 until the stack is empty.

We shall not see the implementation of Depth First Traversal (or Depth First Search) in C programming language
