What is the primary difference between BFS and DFS in graph traversal?

BFS uses a stack, while DFS uses a queue.
BFS explores all neighbors at the present depth before moving on, while DFS explores as far as possible along a branch.
BFS is faster than DFS in all cases.
DFS is used for finding the shortest path, while BFS is not.

What is the primary difference between BFS and DFS in graph traversal?

Step 1: Understand that BFS stands for Breadth-First Search and DFS stands for Depth-First Search.
Step 2: In BFS, you start at a node and explore all its immediate neighbors first.
Step 3: After exploring all neighbors of the starting node, you move to the next level of neighbors.
Step 4: In DFS, you start at a node and go as deep as possible down one path before backtracking.
Step 5: This means you might explore one branch completely before moving to another branch.
