What is the main disadvantage of DFS compared to BFS?
Step 1: Understand what DFS (Depth-First Search) and BFS (Breadth-First Search) are. DFS explores as far down a path as possible before backtracking, while BFS explores all neighbors at the present depth before moving on to nodes at the next depth level.
Step 2: Recognize that DFS can follow a long path that doesn't lead to a solution, which means it might take a long time to find the correct answer.
Step 3: Compare this to BFS, which explores all options at the current level first, ensuring that it finds the shortest path to a solution more efficiently in many cases.
Step 4: Conclude that the main disadvantage of DFS is that it can get stuck in deep paths, making it less efficient in certain situations compared to BFS.
