When should I use BFS instead of DFS?
BFS, or Breadth-First Search, is ideal for finding the shortest path in unweighted graphs. It's also useful when you need to explore all neighbors at the present depth before moving on.
What about DFS? When is it better?
DFS, or Depth-First Search, is better for scenarios where you want to explore as far as possible down one branch before backtracking. It's often used in pathfinding and topological sorting.
Can you give me an example of a problem where BFS is preferred?
Sure! A classic example is the shortest path problem in an unweighted graph, like finding the quickest route on a map.
And what about a scenario for DFS?
DFS is preferred in puzzles like mazes, where you want to explore all possible paths to find a solution.
