Can you explain BFS and DFS algorithms with examples?

Can you explain BFS and DFS algorithms with examples?

Sure! BFS (Breadth-First Search) explores nodes level by level, while DFS (Depth-First Search) goes as deep as possible before backtracking. Would you like examples for both?

Yes, please provide examples for both algorithms.

For BFS, imagine a tree structure where you start at the root and explore all its neighbors before moving to the next level. For example, if you have a tree with nodes A, B, C, and D, BFS would visit A, then B and C, and finally D.

For DFS, you would start at the root and go as deep as possible down one branch before backtracking. Using the same tree, DFS would visit A, then B, then D, and backtrack to C.

What are the practical applications of BFS and DFS?

BFS is often used in shortest path algorithms, like finding the shortest route in a map. DFS is useful in scenarios like puzzle solving, pathfinding in mazes, and topological sorting.
