What is the complexity of graph traversal algorithms like DFS and BFS?
The time complexity of both Depth-First Search (DFS) and Breadth-First Search (BFS) is O(V + E), where V is the number of vertices and E is the number of edges.
Are there any differences in space complexity between DFS and BFS?
Yes, DFS has a space complexity of O(h), where h is the maximum height of the tree, while BFS has a space complexity of O(V) due to the queue used to store nodes.
In what scenarios would you prefer one algorithm over the other?
You might prefer DFS for pathfinding in deep graphs or when memory is limited, while BFS is better for finding the shortest path in unweighted graphs.
Can you explain how the complexity changes with different data structures?
Certainly! The choice of data structure can affect the efficiency of traversal. For example, using an adjacency list is generally more space-efficient than an adjacency matrix.
