FAQs
Question: What is the main difference between BFS and DFS? Answer: BFS explores all neighbors at the present depth prior to moving on to nodes at the next depth level, while DFS explores as far as possible along each branch before backtracking.
Question: How can I apply BFS in real-world scenarios? Answer: BFS is commonly used in networking to find the shortest path in unweighted graphs, such as routing protocols.

Q. In a binary tree, which traversal method is most similar to DFS?
A.
Level-order traversal
B.
In-order traversal
C.
Breadth-first traversal
D.
Random traversal
Solution
In-order traversal is a type of DFS as it explores the left subtree, then the node, and finally the right subtree.
Q. Which traversal method is typically used to find the shortest path in an unweighted graph?
A.
Depth-First Search
B.
Breadth-First Search
C.
Dijkstra's Algorithm
D.
A* Search
Solution
BFS is used to find the shortest path in an unweighted graph because it explores all neighbors at the present depth prior to moving on to nodes at the next depth level.
