What is the primary purpose of Depth-First Search (DFS)?

To explore as far as possible along each branch before backtracking
To traverse a graph level by level
To find the shortest path in a graph
To detect cycles in a graph

Which data structure is commonly used to implement DFS?

Stack
Queue
Priority Queue
Linked List

What is the time complexity of DFS for a graph with V vertices and E edges?

O(V + E)
O(V²)
O(E log V)
O(V log E)

Which type of graph is suitable for DFS traversal?

Both directed and undirected graphs
Only weighted graphs
Only acyclic graphs
Only connected graphs

What is the first step in DFS traversal?

Mark the starting vertex as visited
Enqueue the starting vertex
Push the starting vertex onto the stack
Sort all vertices in ascending order
