What is the main difference between BFS and DFS?

BFS uses a stack, DFS uses a queue
BFS explores neighbors level by level, DFS explores as far as possible along a branch
BFS is faster than DFS
DFS is used for unweighted graphs only

What is the main difference between BFS and DFS?

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 neighbors first before moving to the next level of neighbors.
Step 3: In DFS, you start at a node and go as deep as possible down one path before backtracking to explore other paths.
Step 4: Visualize BFS as a wave spreading out from the starting point, while DFS is like going down a path until you hit a dead end.
