Step 1: One of the standard rule before starting with DFS algorithm is that DFS puts each vertex of graph into two categories i.e. Visited & Non Visited. Step 2: Keeping in mind that each vertex is visited at least once without making cycles. Step 3: First, need to put any one graph vertices on top of the stack.
